Natural Disasters Essay for Students and Children

500+ words essay on natural disasters.

A Natural disaster is an unforeseen occurrence of an event that causes harm to society. There are many Natural disasters that damage the environment and the people living in it. Some of them are earthquakes , cyclones, floods, Tsunami , landslides, volcanic eruption, and avalanches. Spatial extent measures the degree or severity of the disaster.

Levels of Disaster

The severity or degree of damage can be further divided into three categories:

Small Scale Disasters: Small scale disasters are those that extend from 50 Kms. to 100 Kms. So this kind of disasters does not cause much damage.

Medium-scale disasters: Medium Scale disasters extend from 100 Kms to 500 Kms. These cause more damage than a small scale disaster. Moreover, they can cause greater damage if they occur in colonial states.

Large Scale Disasters: These disasters cover an area of more than 1000 Kms. These cause the most severe damage to the environment. Furthermore, these disasters can even take over a country if the degree is high. For instance, the wiping out of the dinosaurs was because of a large scale natural disaster.

Types of Disasters

Causes: These can cause of releasing of the energy. This release is from the core of the earth. Furthermore, the release of energy causes seismic waves. Rupturing of geological faults causes earthquakes. But other events like volcanic eruptions, landslides mine blasts can also cause it.

Landslides: Landslides is the moving of big boulders of rocks or debris down a slope. As a result, landslides occur on mountains and hilly areas. Moreover, landslides can cause destruction to man-made things in many ways.

Causes: Gravitational pull, volcanic eruptions , earthquakes can cause landslides. Moreover, soil erosion due to deforestation is also a cause of landslides.

Avalanches: Avalanches are like landslides. But instead of rocks thousand tons of snow falls down the slope. Moreover, this causes extreme damage to anything that comes in its way. People who live in snowy mountains always have fear of it.

Causes: Avalanches takes places when there is a large accumulation of snow on the mountains. Moreover, they can also occur from earthquakes and volcanic eruptions. Furthermore, the chances of surviving an avalanche are very less. This is because people die of hypothermia in it.

Tsunami: Tsunami is the production of very high waves in oceans and seas. Moreover, the displacement of the ground causes these high waves. A tsunami can cause floods if it occurs near shores. A Tsunami can consist of multiple waves. Moreover, these waves have a high current. Therefore it can reach coastlines within minutes. The main threat of a tsunami is if a person sees a Tsunami he cannot outrun it.

Causes: Tsunami is unlike normal eaves that occur due to the wind. But Tsunami is waves that occur by ground displacement. Thus earthquakes are the main causes of Tsunamis.

What Natural Disasters?

A natural disaster is a major event caused by Earth’s natural processes, resulting in widespread destruction to the environment and loss of life. It typically follows a natural hazard, such as living in an area with active fault lines, as exemplified by the Gujarat Earthquake in 2001.

It’s noteworthy that some natural hazards can be influenced by human activities. For instance, deforestation, mining, and agriculture can trigger landslides, emphasizing the interconnectedness between natural processes and human actions.

Types of Natural Disasters

Natural disasters can be categorized into geological, hydrological, meteorological, space disasters, and other types.

Geological Disasters

An avalanche refers to a sudden and rapid descent of snow, ice, and debris down the slopes of a mountain or a steep incline. This natural occurrence is often triggered by factors such as snow accumulation, temperature changes, or disturbances, leading to a cascading flow of snow, ice, and accompanying debris down the mountainous terrain. Avalanches can pose significant threats to both human settlements and natural landscapes, impacting the ecosystem and potentially causing harm to individuals caught in their path.

Landslides are geological events characterized by the movement of rock, soil, and debris down a slope. This movement can be triggered by various factors, including heavy rainfall, earthquakes, volcanic activity, or human-induced disturbances such as deforestation. Landslides can result in the displacement of large volumes of earth material, leading to the destruction of infrastructure, alteration of landscapes, and posing risks to communities situated in landslide-prone areas.

Earthquakes

Earthquakes are seismic events caused by the shifting of tectonic plates beneath the Earth’s surface. This movement generates intense shaking of the ground, resulting in seismic waves that propagate through the Earth. Earthquakes vary in magnitude, with higher magnitudes indicating more significant seismic energy release. These natural phenomena can have widespread and devastating impacts on communities, causing structural damage to buildings, triggering landslides, and sometimes leading to tsunamis in coastal regions.

Sinkholes are abrupt collapses in the Earth’s surface, occurring due to underground erosion of soluble bedrock, such as limestone or gypsum. When water gradually dissolves these rocks, underground voids or cavities can form. If the overlying material can no longer support its own weight, it collapses into the void, creating a sinkhole. These sudden depressions in the ground can appear without warning, posing risks to infrastructure and landscapes. Human activities, such as excessive groundwater pumping, can exacerbate sinkhole formation.

Volcanic Eruption

A volcanic eruption is the forceful release of magma, ash, and gases from a volcano. This occurs when pressure beneath the Earth’s crust causes molten rock to erupt through the surface. Volcanic eruptions can take various forms, including explosive eruptions with ash clouds and pyroclastic flows or effusive eruptions with the slow release of lava. The consequences of volcanic activity can be severe, impacting the surrounding environment, climate, and posing hazards to nearby communities through ashfall, lava flows, and even secondary events like lahars (mudflows) or volcanic tsunamis.

Hydrological Disasters

A flood is a natural disaster characterized by the overflow of water onto areas that are typically dry. This can occur due to various reasons, including heavy rainfall, storm surges, rapid melting of snow or ice, or the sudden release of water from natural reservoirs such as dams. Floods can result in extensive damage to infrastructure, displacement of populations, loss of crops, and contamination of water sources. The severity of floods can range from localized flash floods to large-scale riverine floods, each posing unique challenges for preparedness, response, and recovery efforts.

A tsunami is a series of ocean waves with extremely long wavelengths and high energy, typically caused by underwater disturbances such as earthquakes, volcanic eruptions, or underwater landslides. When these disturbances displace a large volume of water, it sets off a chain reaction that results in the formation of powerful and often destructive tsunami waves. Tsunamis can travel across entire ocean basins, making them capable of impacting coastlines far from the source. The immense energy carried by these waves can lead to widespread inundation of coastal areas, causing significant loss of life, destruction of infrastructure, and long-term economic and environmental consequences.

Limnic Eruption

A limnic eruption, also known as a lake overturn, is a rare and potentially deadly natural event that involves the sudden release of dissolved gases from the depths of a lake. This phenomenon typically occurs in deep, stratified lakes where layers of water have different temperatures and chemical compositions. If triggered by a geological event or other factors, such as volcanic activity or an earthquake, the deep layers of water may undergo a rapid and violent mixing process. This mixing causes the release of large amounts of dissolved gases, such as carbon dioxide, into the lake and its surroundings. The discharged gases can be lethal to both aquatic life and nearby human populations, as they can displace the oxygen necessary for survival. While relatively infrequent, limnic eruptions have the potential for catastrophic consequences, emphasizing the importance of monitoring and understanding the conditions of deep lakes prone to such events.

Meteorological Disasters

Cyclonic storm.

A cyclonic storm is a meteorological phenomenon characterized by a rotating low-pressure weather system. These storms are known by different names in various regions, such as hurricanes in the Atlantic and northeastern Pacific, typhoons in the northwestern Pacific, and cyclones in the South Pacific and Indian Ocean. Cyclonic storms derive their energy from warm ocean waters, and their distinctive circular motion is driven by the Earth’s rotation. These storms can unleash powerful winds, heavy rainfall, and storm surges, causing widespread damage to coastal areas. The intensity of cyclonic storms is categorized on scales like the Saffir-Simpson Hurricane Wind Scale, with higher categories indicating stronger and more destructive storms.

A blizzard is an intense and severe snowstorm characterized by strong winds, low temperatures, and reduced visibility due to blowing snow. Blizzards typically occur in regions with cold climates and sufficient moisture content in the air. The combination of heavy snowfall and strong winds creates whiteout conditions, making travel extremely hazardous. The impact of blizzards extends beyond transportation disruptions to include power outages, damage to infrastructure, and threats to human safety. Effective preparation and response strategies are crucial to mitigating the risks associated with blizzards.

Cold Waves, Heat Waves, Drought

Extreme temperature events encompass cold waves, heat waves, and droughts, each presenting unique challenges to ecosystems and human societies. Cold waves involve an extended period of unusually cold temperatures, potentially leading to freezing conditions, frostbite, and stress on heating systems. Heat waves, on the other hand, bring prolonged periods of excessively high temperatures, causing heat-related illnesses, stressing power grids, and posing risks to vulnerable populations. Droughts involve prolonged periods of abnormally low precipitation, leading to water scarcity, crop failures, and ecological imbalances. These extreme temperature events underscore the importance of adaptive measures, water conservation, and public health interventions to mitigate their impacts.

Hailstorms, Tornadoes

Hailstorms and tornadoes are destructive meteorological phenomena associated with severe thunderstorms. Hailstorms involve the formation of large hailstones due to updrafts in thunderstorm clouds. These hailstones can cause damage to crops, vehicles, and structures. Tornadoes are violent and rotating columns of air extending from thunderstorms to the ground. They can have devastating impacts, destroying buildings, uprooting trees, and posing severe threats to life and property. Early warning systems, storm shelters, and community preparedness are essential for minimizing the risks associated with hailstorms and tornadoes.

Space Disasters

Solar flares.

Solar flares are intense bursts of energy and radiation emanating from the Sun’s surface. They occur in the Sun’s outer atmosphere, or corona, and are triggered by the complex interplay of magnetic fields. During a solar flare, there is a rapid release of energy in various forms, including X-rays, ultraviolet light, and charged particles. The sudden increase in solar radiation can impact space weather and cause disturbances in the Earth’s atmosphere. While solar flares do not pose a direct threat to human health, they can affect communication systems, navigation equipment, and power grids. Monitoring solar activity is crucial for space agencies and utilities to minimize potential disruptions caused by these energetic outbursts.

Gamma-Ray Bursts

Gamma-ray bursts (GRBs) are highly energetic explosions that release an extraordinary amount of gamma-ray radiation, the most energetic form of electromagnetic radiation. These bursts can last from milliseconds to several minutes and are observed in distant galaxies. The exact mechanisms that trigger gamma-ray bursts are still under investigation, but they are often associated with cataclysmic events such as the collapse of massive stars or the merging of binary neutron stars. While GRBs are not a direct threat to Earth due to their distance, they provide valuable insights into the processes shaping the universe. The energy released in gamma-ray bursts is so immense that, if occurring nearby, it could have severe consequences for life on Earth, making their study important for understanding the broader cosmic landscape.

Impact Events

Impact events refer to collisions between celestial bodies, such as asteroids or comets, and planets or moons. One of the most well-known impact events in Earth’s history is the Chicxulub impact, which occurred approximately 66 million years ago. This impact, involving a large asteroid, is widely believed to be a major contributing factor to the mass extinction event that wiped out the dinosaurs. Impact events can have catastrophic consequences, causing widespread fires, tsunamis, and altering the Earth’s climate. While large impacts are rare on human timescales, studying and monitoring near-Earth objects is crucial for understanding potential threats and developing strategies for planetary defense. Advances in space observation technology allow scientists to identify and track these celestial bodies, providing early warning and the potential for mitigating measures if a significant impact threat is identified.

10 Types of Natural Disasters

What Are Natural Disasters?

A natural disaster is a sudden and extreme event caused by nature that can cause damage and harm people.

Examples include earthquakes, hurricanes, tornadoes, floods, wildfires, volcanic eruptions, and tsunamis.

These events can have serious consequences for communities and the environment.

Today, we’ll go through all 10 types of natural disasters .

1. Hurricanes

A hurricane is a type of tropical storm, but much more powerful. It’s like a gigantic, spinning storm that forms over warm ocean waters.

Hurricanes have powerful winds that blow things around, heavy rain causes flooding, and storm surges flood coastal areas. 

Meteorologists classify them into categories based on their wind speed, with Category 5 being the most powerful.

2. Tornadoes

Tornadoes form when warm and cold air collide during big thunderstorms. This collision can force the wind to start spinning in a circle.

When a tornado comes, it can be extremely destructive, like a powerful giant vacuum cleaner that sucks up everything in its path.

Imagine a tornado as a long, twisting tube of wind and clouds that reaches down from the sky to the ground. Inside this spinning tube, the wind can be so strong that it can pick up houses, cars, and trees and toss them around like toys.

Tornadoes are natural disasters because they can cause a lot of damage and are very dangerous to people. They’re not something we can control or prevent, but we can try to stay safe by listening to weather warnings and taking shelter.

3. Volcanoes

Volcanoes form hot molten rock, ash, and gases from deep within the Earth. They can burst out through an opening, often creating an eruption.

They typically occur where two plate tectonic boundaries meet such as the Ring of Fire . But they can also happen at subduction zones, hot spots, and mid-oceanic ridges.

A volcano can lead to the release of lava and ash because of the Earth’s internal heat and activity. All the parts of a volcano like lava bombs and lahar can cause damage to the surrounding areas. 

4. Earthquakes

An earthquake happens when there’s a sudden release of energy in the Earth’s crust. This creates seismic waves that cause the ground to shake.

This release of energy happens because of the movement of tectonic plates beneath the Earth’s surface.

Earthquakes can range in size and strength, from small ones that are hard to notice to big ones that can damage buildings and landscapes.

They can also lead to aftershocks , which are smaller tremors that follow the main earthquake.

5. Tsunamis

A tsunami is a super-sized ocean wave that can be extremely destructive. It happens when something big, like an undersea earthquake disturbs the ocean floor.

This disturbance creates a massive amount of energy, which sends powerful waves spreading across the ocean.

As these waves approach shallower coastal areas, they can grow in height and speed, causing massive flooding when they reach the shore.

Tsunamis can be very dangerous and lead to significant damage and loss of life in coastal regions.

6. Droughts

A drought is a prolonged period of abnormally low rainfall in a particular region. This can cause water shortages and impact the environment and agriculture.

In a drought, there isn’t sufficient water for people, plants, and animals. This causes dry soil, less crop growth, and water restrictions for communities.

Droughts can greatly impact ecosystems and make life difficult for people who rely on water. 

7. Landslides

A landslide is a sudden movement of dirt, rocks, or even entire chunks of land that suddenly moves downhill .

It can happen because of heavy rain, earthquakes, or other factors that make the ground unstable.

Landslides can be slow and gradual, or they can be very fast and destructive .

They often cause damage to homes, roads, and the natural landscape in the affected area.

8. Forest fires

A forest fire, also known as a wildfire, is when a forest suddenly catches fire and spreads quickly to the surrounding area.

It’s a fast-spreading, uncontrolled fire that occurs in forests, grasslands, or wild areas. Fires can start from lightning, human activities, or even volcanic eruptions .

Forest fires can cause a lot of damage. They burn trees, plants, and wildlife. But they can also put nearby communities and the environment at risk. Firefighters work hard to control and extinguish these fires to minimize their impact.

9. Flooding

Water overflowing onto dry land is called flooding . Flooding can occur because of heavy rain, melting snow, or rising rivers, lakes, or oceans. 

Floods can be slow and gradual, or they can come on quickly, depending on the cause. They can damage homes, roads, and farmland and can be very dangerous.

A subcategory is flash floods, which is a sudden and unexpected rush of water . Flash floods are very dangerous because they occur suddenly and the fast-moving water can carry debris, putting people and property at risk.

10. Typhoons

A typhoon is essentially the same thing as a hurricane, but it’s called a typhoon in the western Pacific Ocean and the South China Sea.

In other parts of the world, such as the Atlantic Ocean and the northeastern Pacific, we refer to these powerful storms as hurricanes. 

Typhoons and hurricanes are big tropical storms with strong winds and heavy rain that can cause a lot of damage. They usually hit coastal areas.

Natural disasters are powerful and often devastating events that result from the forces of nature. 

They encompass a wide range of phenomena, including hurricanes, typhoons, cyclones, volcanoes, earthquakes, tsunamis, droughts, landslides, forest fires, and flooding.

These events have the potential to cause significant damage to communities and the environment.

We can reduce destruction and loss by understanding nature and taking appropriate measures. Let’s build resilient, disaster-resistant societies.

Essay # 1. Meaning of Natural Calamities:

Natural calamities are the calamities which are inflicted by God, or Nature, or man and his world. At these calamities, the unseen hand wreaks havoc in the part of the world it chooses to act upon. On these natural activities of nature no scientific or technological developments can wield any control.

They can occur as and when and where ordains it. Natural calamities can be of many different kinds, but the similarly in all, is their massive destruction in the area of their occurrence. The natural disasters are of many kinds, they are drought and famine, flood, earthquake, hailstrom and a cyclone.

In the wake of all these, in one sweep there is complete devastation and destruction, due to which normal life comes to a standstill. Loss of life is well nigh complete, and belongings of people get lost, blown away or swept away. The scene is one of the awe, of some unknown power that appears to wreak some revenge on the people of the area.

One feels that, there will never again be life in the area, there will never again come up any construction in the area. But, nature plays its part in this also, and even after the most ghastly disaster, life has come up blooming as ever as before in areas of such devastation.

ADVERTISEMENTS: (adsbygoogle = window.adsbygoogle || []).push({}); Essay # 2. Types of Natural Calamities:

Different natural, calamities can be distinguished from each other in terms of their nature and extent of their impact. Calamities like: earthquakes, hailstorms, avalanches, landslides, etc., occur quite suddenly but they are restricted in their impact in terms of time and space. Similarly, though floods and cyclones occur with some element of warning yet their occurrence is confined in duration.

Drought, on the other hand, spans over a much longer time-frame and its adverse impact on the economic activities and life of an area is of a more lasting nature. The measures required to meet the threats posed by different calamities, therefore, differ considerably in terms of disaster preparedness and amelioration of the economic and social life of the affected people.

Major and Minor Calamities:

Natural calamities may be broadly grouped into major and minor types depending upon their potential to cause damage to human life and property. While natural calamities like: earth quakes, droughts, floods and cyclones could be regarded as major, hailstorms, avalanches, landslides, fire accidents, etc. Whose impact is localized and intensity of the damage is much less can be categorized as minor calamities.

Minor calamities like: hailstorms, avalanches, landslides and fires also occur without any appreciable degree of forewarning and cause damage to properties and lives. However, areas prone to such disasters also could be identified and certain precautionary measures taken in the context of potential threat requiring general awareness and an ability to relate to a predefined system of appropriate responses on the part of the local administration.

🌊 Natural Disaster Essay 200 Words

Below you will find a short natural disaster essay for 200 words. It explores the causes and effects of the tsunami in Japan in 2011.

Tsunami in Japan: Causes and Effects The proximity of the deadliest disasters is often unpredictable. As a result, the consequences of a tsunami can exceed any possible expectations. This essay looks for the decisive factors that caused the tsunami in Japan in 2011 and its results for the local population and other countries. The causes were out of human control and could not be predicted. The Pacific plate moved in the horizontal and vertical plane, advancing beneath the Eurasian Plate. It displaced the seawater above and entailed several destructive waves. The disaster had enormous consequences for the Japanese people and their economy. It killed almost 16,000 people, although the country had a sophisticated alarming system. Besides, the earthquake caused fires and explosions at oil factories. The cooling system of the Fukushima Daiichi Nuclear Power Plant went out of service. Two people were lost, and many were injured. Nissan, like many other large corporations, had to suspend the operation of its four factories. The economic losses due to the catastrophe amounted to 300 billion dollars. But the disaster moved to other places. On 24 March 2011, the earthquake in the east of Myanmar claimed the lives of 60 people and destroyed 300 buildings. As we can see, everything is linked on our planet. Movements of the earth’ crust in any part of the world bring about earthquakes and tsunami in other countries.

The Economic Effects of the Dust Bowl Drought When someone says “a natural disaster,” we usually imagine an earthquake or a tsunami. Buildings are destroyed, and property is lost. But imagine a scenario of a devastating drought, which happened in the US in the 1930s. Its effect is less visible because it lies in the domain of the national economy. This essay reveals the economic consequences of the Dust Bowl drought. During the third decade of the XX century, strong winds raised choking dust in the southern states, from Texas to Nebraska. People and animals died as the crops failed in the area for several years in a row. The Dust Bowl lasted for almost a decade and was also called “the Dirty Thirties.” This drought intensified the impact of the Great Depression. Local farmers had to migrate to urban areas in search of better conditions and other sources of living. About 2.5 million people moved West from the worst-hit states, namely New Mexico, Texas, Nebraska, Oklahoma, and Kansas. But they found only discrimination, meager salaries, and inhuman working conditions. Many had to live in tents near irrigation ditches. They were called “Okies,” a disdainful name for migrants of any state. Regular rains returned to the southern states by the end of 1939, closing the drought. However, the economic aftermath persisted. The counties that suffered the most failed to recover the agricultural value of their land till the 1950s. Thus, the local population kept decreasing for twenty years. Although a drought does not ruin property, it can tangibly lower human life levels. The Dust Bowl threw people into a lose-lose situation. Their farms were unfit for gaining any profit, and the new places of living gave them no better opportunities. It took two decades to restore public wellbeing in the Southern States.

Researching the worst acts of nature can teach you to value what you have. We hope that this article has made your creative writing more manageable and pleasurable. You can write an essay of any length by simply following our outline. All you will need to do after that is make a cover page for it.

Natural Disasters (Lesson Plan for Unit in Geography)

A geography classroom is a good place for a lesson plan on natural disasters. Design a natural disasters unit study for a multidisciplinary approach.

Natural disasters are an exciting topic for kids to learn about. Earthquakes, volcanoes , avalanches, floods, hurricanes , wildfires , and other natural disasters are dangerous and mysterious to students. Incorporate other subjects into the unit study so that the lesson plans are well-rounded, relevant, and interesting.

There are numerous types of natural disasters including tsunamis, monsoons, hurricanes, tornadoes, volcanoes, earthquakes, floods, thunderstorms, avalanches, blizzards, wildfires, and droughts. The study of natural disasters gives students the opportunity to learn many of the national geography standards while still having fun in the learning process.

The following steps are a natural progression for making a lesson plan for studying natural disasters: learning objectives, learning tools for the lesson, appropriate activities and projects, and assessment.

Objectives for Lesson Plan on Natural Disasters

Table of Contents

Begin planning the unit study on natural disasters by deciding on the learning goals. The National Council for Geographic Education has developed a list of suggested standards in the field of geography.

Teachers who are clear on the learning objectives before creating a lesson plan tend to create unit studies that are well-rounded and relevant. Decide on the main focus: geography, science, or literature, for example. Then, drill down the standards which the students will be taught.

Suggested Reading, Teacher Supplies and Learning Tools for a Lesson Plan on Natural Disasters

Use lots of maps in this lesson plan. Natural disasters occur all over the world, and extreme weather tends to cluster in regions. There are lots of different types of maps available, so try and stick to the classroom budget.

See an extensive recommended reading list for natural disasters unit study to create a well-rounded lesson plan that includes literature, history, math, science, statistics, rescue mission, and nature adventure.

Use worksheets, puzzles, movies, documentary DVD’s, and games in the geography classroom to learn about natural disasters. Invite a University professor or graduate student in meteorology to give a presentation to the class to give students the opportunity to ask questions in person.

Geography games are fun for students. Trivia games are especially helpful because they break down the information into manageable bits which make it easier for students to study. Geography trivia games make learning enjoyable, and friendly competition can be a great motivator. If the classroom is on a tight budget, then make your own geography trivia game for natural disasters.

Activities for Geography Lesson Plan on U.S. National Parks

When designing assignments, consider the materials are chosen, as well as the learning objectives for the lesson plan. For example, when using the National Council for Geographic Education standard 7, “The physical processes that shape the patterns of Earth’s surface,” then an assignment might be a poster montage that shows the geologic processes of a volcano.

The activities will depend on the materials chosen for the lesson plan, as well. For example, if using a book on wildfires, assign an interview with the local fireman or department of natural resources employee.

Other appropriate activities for the lesson plan might include popular movies such as Twister, or educational DVDs about any of the natural disasters. Students could be asked to identify regions of natural disasters on maps or play competitive geography trivia games. Science projects such as building a volcano or creating a survival kit are also appropriate for the classroom.

Assessment & Quizzes for Natural Disasters Lesson Plan

Written tests are a traditional form of assessment of students’ understanding of the material studied. The questions should come from the materials used and should be relevant to the big picture of natural disasters.

For a more informal assessment method, watch the students participate in a geography trivia game that they co-created on the unit study. Judge their knowledge and comprehension of natural disasters based on close observation. Participation and effort in the game could determine students’ final grades, regardless of winning or losing.

When creating a lesson plan for natural disasters or for any physical geography subject, plan first by deciding on the learning objectives and on the resources that will be used. Assignments, activities, and projects should all be designed around those choices. As the lesson plan unfolds during implementation, it should be clear what method of assessment is most appropriate to test the students’ knowledge of natural disasters.

Recommended Book List for Lesson Plan on Natural Disasters Unit

Here are book lists for teaching a unit study about natural disasters. Read about rescue missions, survival stories, statistics, history, and weather science.

An in-depth study of natural disasters includes more than just learning about extreme weather. A unit study on natural disasters includes other subjects such as history, global warming, environmentalism, literature, writing, math, and science.

Let the learning objectives guide book decisions for the lesson plan on natural disasters. Then, design activities, projects, and assignments to revolve around the book choices. Find suggested benchmarks for learning about geography on the National Council for Geographic Education’s web page.

Featured Activity: Teaching about Natural Disasters

Melissa Sullivan , this week’s Educator of the Week , inspires her 5th graders to care about natural disasters through the lens of science, social studies, and math. Read about how she connects her Earth Science lessons to real-world situations.

Activity: Teaching about   Natural Disasters Grade Level: 5 Time Commitment: Two weeks

When I teach, I like to augment my lessons with a local, regional, and global perspective. As part of our Earth Science unit, during one school day we investigated rapid changes in the earth’s surface caused by natural disasters. We incorporated the scientific method, and I guided my students to observe these catastrophes through stream tables. We built our own stream table and simulated the effects of a hurricane and a flash flood.

Throughout the two week unit, I linked the lesson to social studies and math by discussing the social and economic impacts and decisions humans make to lessen the impact of natural disasters. We connected this lesson to a real-world situation by watching news clips of Hurricane Katrina and looked at that area from a bird’s eye view using Google Earth. We then discussed how the levee in New Orleans was not tall or strong enough to withstand Hurricane Katrina.

One of my students…remarked during this lesson, “I love fifth grade!” when he was able to start making connections to the world outside of the classroom.

We also touched upon how surrounding regions were impacted through refugees and strained resources. The discussion, along with a bit of scaffolding, incorporated the economic impact of the disaster and how disasters like Katrina are common throughout the world. This included ideas of cost versus function with engineering (i.e. how tall/strong to make a levee) and city planning in order to offer solutions to prevent such catastrophes in the future.

How did this activity impact your students?

My students were eager to learn how to help when disasters occur. They enjoyed learning about the importance of planning and the consequences of poor planning.

One of my students who had walked into my classroom with a bit of apathy at the beginning of the year remarked during this lesson, “I love fifth grade!” when he was able to start making connections to the world outside of the classroom.

How does teaching with a geo-education mindset impact your students?

One of my teaching goals is to connect science and social concepts to promote geo-literacy. I strive to empower my students to become decision-makers by the knowledge acquired through lessons. For example, I take science concepts such as how humans change the environment and link it to Ten on Tuesday , a concept that if each citizen picks up ten pieces of trash on Tuesday, cities can reduce the amount of litter. My students are so excited about helping the environment that they voluntarily spend part of their recess time on Tuesdays picking up trash.

What is one simple activity to get students to think about their world?

After giving a lesson on a topic, a teacher can write on the whiteboard three columns of words: local, regional, and global, and lead a discussion on these that relate to the lesson. The repetition of these words over time will encourage students to relate future concepts on all three levels.

Do you have a favorite book that inspires your teaching?

My favorite teaching book is Teach Like Your Hair’s on Fire: The Methods and Madness Inside Room 56 by Rafe Esquith, an inspiring teacher who taught in a low-income area of Los Angeles. His students, despite being first generation immigrants, scored in the top 1% of standardized tests and went on to attend Ivy League Universities. He links learning to the “real world” through movies, art, music, and baseball.

Do you have a favorite quote that inspires you in your life or in your teaching?

“If your dreams do not scare you, they are not big enough.” – Ellen Johnson Sirleaf, the first female President of Liberia

Melissa Sullivan is a 5th grade bilingual teacher (English/Spanish) at Seabourn Elementary in Mesquite, Texas. She is passionate about getting her students to think locally and globally and care about the planet. This year her class participated in the Global Monster Project .

Introduction to Geographic Science

1.5 Understanding Natural Disasters

Science of natural disasters.

Because of the scientific method, we now understand where and why most natural disasters occur. For example, because of the theory of plate tectonics, we know why 90 percent of all earthquakes and volcanoes occur along the Pacific Ocean’s outer edges, called the Ring of Fire . The plate tectonics theory has also helped explain why some volcanoes are more explosive and active than others. We also understand that different tectonic plate boundaries produce different fault lines and, thus, several types of earthquakes.

Many natural hazards have seasons, especially those controlled by external forces. The United States has more tornadoes than the rest of the world combined, yet it occurs in the spring and early fall. Landslides are more prone in the spring when snow begins to melt, and the saturated ground causes unstable slopes to slide. Wildfires are frequent in the middle of the summer and early fall when the land is dry, and afternoon thunderstorms in arid climates produce lightning without any precipitation. Furthermore, hurricane season in the Northern Hemisphere peaks between August and September when the Atlantic Ocean is warmest.

Since hazards are statistically predictable in some manner, it becomes essential to develop a warning system. Predictions like weather predictions state that they will occur at a specified time, date, and intensity. It is like saying, “A major snowstorm will reach Salt Lake City at 4:30 PM for the commute home.” A forecast states a probability of something occurring, such as “40 percent of showers today.” Forecasts are much broader than predictions.

When a natural disaster event is about to happen or has occurred, a system has been set up to alert the public. A watch is issued when the conditions for an event are right. A tornado may form if a severe thunderstorm is strong enough and rotating. Alternatively, if an earthquake with a magnitude of 7.5 strikes somewhere in the ocean, a tsunami watch may be issued because it was strong enough to generate one. However, a watch does not necessarily mean that it will occur. A warning is sent to the areas that could be impacted if a tornado is spotted on the ground or an ocean sensor records an approaching tsunami.

Determining Risk

A risk assessment must be conducted for a specific geographic area to understand how to prepare for a natural hazard. The risk of a potential hazard is defined as the probability of a disaster multiplied by the consequence to the human environment.

• Risk = Probability of Disaster x Consequence of Disaster

It is essential to determine the potential risk a location has for any disaster to know how to prepare for one. Referring to Salt Lake City again, the probability of an earthquake occurring anytime soon is small, but the consequences to human lives and destruction are exceedingly high. There is a moderately increased risk of an earthquake striking Salt Lake City. One of the limiting factors of risk is knowing the probability of a disaster. Too often, scientific data lacks enough information to determine how a disaster usually occurs in a particular location. This is particularly true with geologic hazards, where geologic time is vastly more extensive than the age of scientific reasoning.

Hazards, Disasters, and Catastrophes

What is the difference between natural hazards, disasters, or catastrophes? A hazard is any natural process or event directly threatening the human environment. The event itself is not a hazard; a function or event becomes a hazard when it threatens human interests. A disaster is the effect of a hazard on society, usually an event that occurs over a limited time in a defined geographic area. The term disaster is used when the interaction between humans and a natural process results in significant property damage, injuries, or loss of life. Finally, a catastrophe is a massive disaster that significantly impacts the human environment and requires considerable time, money, and resources for response and recovery.

Click on the story map below, titled US Hazards, to spatially understand the variety of natural hazards across the United States and their potential impact on society.

Currently, the earthquake that is expected to strike Salt Lake City is just a hazard, a natural process that poses a potential threat to the human environment because it has not occurred yet. If that earthquake turns out to be a moderate 5.0 magnitude earthquake, it will be considered a disaster. However, if the expected 7.0 to 7.5 magnitude earthquake were to occur, it would be viewed as a catastrophe because thousands of people would perish, tens of thousands would be injured, and the economic cost would be billions of dollars. An article by NASA titled The Rising Costs of Natural Hazards talks about how the financial and human cost of natural disasters is rising. Better mitigation efforts will be required to help prepare for these disasters, such as proper building and zoning codes, first responder preparedness, and public education.

In the summer of 2008, China was rocked by a magnitude 8.0 earthquake that killed over 80,000 people. A week earlier, a cyclone struck Burma , killing 130,000. On January 12, 2010, a magnitude 7.0 earthquake killed nearly 300,000 people and leveled the capital city of Port-a-Prince in Haiti . On March 11, 2011, a magnitude 9.0 earthquake generated a tsunami off the coast of eastern Japan , killing 30,000 people. Are natural disasters getting worse? Not really. Humans are overpopulating the Earth and living in more hazard-prone areas. Over the last 70 years, the world’s population has tripled to 6.7 billion. World population projections suggest that the human population will reach 9 billion by 2050. exponentially grow, and 2050 the world’s population will reach 9 billion. Exponential growth means the world’s population will not grow linearly (in a straight line) but rather as a percentage. Our increased population has caused air quality to suffer, reduced the availability of clean drinking water, raised the world’s extreme poverty rate, and made us more prone to natural hazards.

There is also a relationship between the magnitude of an event (energy released) and its frequency (intervals between episodes). The more earthquakes that occur in a particular location, the weaker they tend to be. That is because built-up energy is slowly being released constantly. However, if there are long intervals between one earthquake and the next, the energy can build and produce a stronger earthquake. That is the problem with earthquakes along the Wasatch Front of Utah. The interval or frequency between earthquakes tends to be 1,500 years, so the magnitude tends to be high because of the built-up energy. We will want to get this earthquake over with at some point because the longer it waits, the worse it will be.

Primary and Secondary Effects

​Natural disasters cause two types of effects: direct and indirect . Direct effects, also called primary effects , include destroyed infrastructure and buildings, injuries, separated families, and even death. Indirect , called secondary effects , are things like contaminated water, disease, and financial losses. In other words, indirect effects are things that happen after the disaster has occurred.

How we build our cities will significantly determine how many lives are saved in a disaster. For example, we should not be building homes in areas that are prone to landslides, liquefaction, or flash floods. Instead, these places should be left as open spaces such as parks, golf courses, or nature preserves. This is a matter of proper zoning laws, which the local government controls. Another way we can reduce the impact of natural disasters is by having evacuation routes, disaster preparedness and education, and building codes so that our buildings do not collapse on people.

Internal and External Forces

Two forces generate natural hazards: internal forces and external forces . The first is internal forces generated by the Earth’s internal heat, creating geologic hazards like earthquakes, volcanoes, and tsunamis. The theory of plate tectonics proposes that internal heating from the Earth’s core causes large tectonic plates that make up the planet’s continents and oceans to move around like bumper cars, where they either slam into each other or pull apart.

External forces influence weather, climate, and landslides. Heating from the Sun causes differential heating on the surface, creating our weather and all its associated hazards. These external forces generate flash floods, tornadoes, hurricanes, supercells, and climatic disasters such as droughts and famines.

Human Population

Sometimes, people will ask if natural disasters are getting worse. This apocalyptic concern has only increased because of climate change or COVID-19. From a geologic perspective, the data suggests that natural events are not continuing to get worse. That does not mean that issues such as climate change should be discounted, far from it. But one consistent variable is that human population growth is causing humans to be more in the way of natural events.

Demography is the study of how human populations change over time and space. It is a branch of human geography related to population geography , which examines the spatial distribution of human populations. Geographers study how populations grow and migrate, how people are distributed worldwide, and how these distributions change over time.

For most of human history, few people lived on Earth, and the world population grew slowly. Only about five hundred million people lived on the entire planet in 1650 (less than half of India’s population in 2000). Things changed dramatically during Europe’s Industrial Revolution in the late 1700s and 1800s, when declining death rates due to improved nutrition and sanitation allowed more people to survive to adulthood and reproduce. The population of Europe increased. However, by the middle of the twentieth century, birth rates in developed countries declined, as children had become a financial liability rather than an economic asset to families. Fewer families worked in agriculture, more families lived in urban areas, and women delayed the age of marriage to pursue education, resulting in a decline in family size and a slowing of population growth. The population is declining in some countries (e.g., Russia and Japan), and the average age in developed countries has been rising for decades. The process just described is called the demographic transition .

At the beginning of the twentieth century, the world’s population was about 1.6 billion. One hundred years later, there were roughly six billion people worldwide, and as of 2011, the number was approaching seven billion. This rapid growth occurred as the demographic transition spread from developed countries to the rest of the world. During the twentieth century, death rates due to disease and malnutrition decreased in every corner of the globe. In developing countries with agricultural societies, however, birth rates remained high. Low death rates and high birth rates resulted in rapid population growth.

Meanwhile, birth rates and family sizes have declined in most developing countries as people leave agricultural professions and move to urban areas. This means that population growth rates, while still higher in the developing world than in the developed world, are declining. Although the exact figures are unknown, demographers expect the world’s population to stabilize by 2100 and decline.

The world’s population growth rate has primarily occurred in developing countries, whereas populations are stable or declining in Europe and North America. The world’s population increase is pronounced on the continent of Asia: China and India are the most populous countries, each with more than a billion people, and Pakistan is an emerging population giant with a high population growth rate. The continent of Africa has the highest fertility rates in the world. The most striking paradox within population studies is that while there has been a decline in fertility (a declining family size) in developing countries, the world’s population will grow by 2030 because of the compounding effect of many people already in the world. Even though population growth rates are in decline in many countries, the population is still growing. A small growth rate on a broad base population still results in the birth of many millions of people.

As of May 2020, the United States Census Bureau estimates the world population is nearly 7.65 billion, with a growth rate of roughly 1.07 percent, or approximately 82 million people annually. The world population reached 6 billion in 1999 and 7 billion in 2011. If the current growth rate continues, the human population will reach 8 billion by 2023 and hopefully level off at roughly 10 billion by 2055. Between 2010 and 2050, world population growth will be generated exclusively in developing countries.

The world’s three most significant population clusters are the regions of eastern China, South Asia, and Europe. Southeast Asia also has large population clusters. Additionally, large population centers exist in various countries with high urbanization. An example is the urbanized region between Boston and Washington, DC, including New York City, Philadelphia, Baltimore, and neighboring metropolitan areas, often called megalopolis. The coastal country of Nigeria in West Africa and the island of Java in Indonesia are good examples of large population clusters centered in the tropics.

Social dynamics and geography will determine where the new additions to the human family will live. Providing food, energy, and materials for these additional humans will tax many countries, and poverty, malnutrition, and disease are expected to increase in regions with poor sanitation, limited clean water, and a lack of economic resources. In 2010, more than two billion people (one-third of the planet’s population) lived in abject poverty and earned less than the equivalent of two US dollars per day. The carrying capacity of the world is not and cannot be known. How many humans can the Earth sustain indefinitely? There is the possibility that we have already reached the threshold of its carrying capacity .

The human population will continue to grow until it either crashes due to the depletion of resources or stabilizes at a sustainable carrying capacity. Population growth takes a toll on the Earth as more people use more environmental resources. The areas most immediately affected by increased populations include forests (a fuel resource and a source of building material), freshwater supplies, and agricultural soils. These systems get overtaxed, and their depletion has profound consequences. Type C climates, which are moderate and temperate, are usually the most productive and are already vulnerable to severe deforestation, water pollution, and soil erosion. Maintaining adequate food supplies will be critical to supporting a sustainable carrying capacity. The ability to transport food supplies quickly and safely is a significant component of managing the conservation of resources. Deforestation by humans using wood for cooking fuel is already a severe concern in arid type B climates.

Population Demographics

The Industrial Revolution, which prompted the shift in population from rural to urban, also encouraged market economies, which have evolved into modern consumer societies. Various theories and models have been developed to help explain these changes. For example, in 1929, the American demographer Warren Thompson developed the Demographic Transition Model (DTM) to explain population growth based on an interpretation of demographic history. A revised version of Thomson’s model outlines five stages of the demographic transition from traditional rural to modern urban societies.

Stage 1: Low Growth Rate

Humans have lived in the first stage of the DTM for most of our existence. In this first stage, CBRs and CDRs fluctuated regionally, globally, and over time because of living conditions, food output, environmental conditions, war, and disease. The natural increase of the world was stable because CBRs and CDRs were about equal. However, around 8,000 BC, the world’s population grew dramatically due to the agricultural revolution. During this time, humans learned to domesticate plants and animals for personal use and became less reliant on hunting and gathering for sustenance. This allowed for more stable food production and allowed village populations to grow. War and disease prevented population growth from occurring on a global scale.

Stage 2: High Growth Rate

Around the mid-1700s, global populations grew ten times faster than in the past because of the Industrial Revolution. The Industrial Revolution brought with it a variety of technological improvements in agricultural production and food supply. Increased wealth in Europe and later North America because the Industrial Revolution meant more money and resources could be devoted to medicine, medical technology, water sanitation, and personal hygiene. Sewer systems were installed in cities; thus, public health improved. All this dramatically caused CDRs to drop around the world. At first, CBRs stayed high as CDRs dropped, causing populations to increase in Europe and North America. Over time, this would change.

Africa, Asia, and Latin America moved into Stage 2 of the demographic transition model two hundred years later for more varied reasons than those of their European and North American counterparts. The medicine created in Europe and North America was brought into these developing nations, creating what is now called the medical revolution. This revolution or diffusion of medicine to this region caused death rates to drop quickly. While the medical revolution reduced death rates, it did not bring with it the wealth and improved living conditions and development that the Industrial Revolution created. Global population growth is most significant in the regions still in Stage 2.

Stage 3: Moderate Growth Rate

Europe and North America have moved to Stage 3 of the demographic transition model. A nation moves from Stage 2 to Stage 3 when CBRs begin to drop while CDRs remain low or even continue to fall. It should be noted that the natural rate of increase in nations within Stage 3 is moderate because CBRs are higher than CDRs. The United States, Canada, and European nations entered this stage in the early 20th century. Latin American nations entered this stage later in the century.

Advances in technology and medicine cause a decrease in IMR and overall CDR during Stage 2. Social and economic changes bring about a decrease in CBR during Stage 3. Countries that begin to acquire wealth tend to have fewer children as they move away from rural-based development structures toward urban-based structures because more children survive in childhood. The need for large families for agricultural work decreases. Additionally, women gained more legal rights and chose to enter the workforce, own property, and have fewer children as nations moved into Stage 3.

Stage 4: Return to Low Growth Rate

A country enters Stage 4 of the demographic transition model when CBRs are equal to or become less than CDRs. When CBRs are equal to CDRs, a nation will experience zero population growth (ZPG). This occurs in many countries where girls do not live as long as they reach their childbearing age due to gender inequality.

A country in the first two stages of the transition model will have a broad base of young people and a smaller proportion of older people. A country in Stage 4 will have a much smaller base of young people (fewer children) but a much larger population of elderly (decreased CDR). A country with a large youth population is more likely to be rural, with high birthrates and death rates, helping geographers analyze a nation’s health care system. Moreover, a country in Stage 4 with a large elderly population will have fewer young people supporting the economy. These two examples represent the dependency ratio mentioned earlier in this chapter. This ratio is the number of young and older adults dependent on the working force.

Human geographers like to focus on the following demographic groups: 0-14 years old, 15-64 years old, and 65 and older. Individuals 0-14 and over sixty-five are considered dependents (though this is changing in older generations). One-third of all young people live in developing nations. Moreover, this places considerable strain on those nations’ infrastructure, such as schools, hospitals, and daycare. Older individuals in more developed countries (MDL) benefit from health care services but require more help and resources from the government and the economy.

Another ratio geographers look at is the number of males compared to females, called the sex ratio . Globally, more males are born than females, but males have a higher death rate than females. However, understanding a country’s sex and dependency ratios helps human geographers analyze fertility rates and natural increases.

As noted earlier, population growth has increased dramatically in the last century. No country is still in Stage 1; very few have moved into Stage 4. Most of the world is either in Stage 2 or 3, which both have higher CBRs than CDRs, creating a human population of over 7.5 billion today.

Stage 5: Population Decline

Many demographers believe a new stage in the DTM should be added to address issues starting to develop in countries within Europe and Japan. CBR would be extremely low, and CDR would increase in this final stage. This would cause the area’s NIR to be negative, leading to declining population growth. This may strain a country’s social safety net programs as it tries to support older citizens who are no longer working and contributing to the economy.

Unnatural Disasters

Former UN Security General Kofi Annan has said, “The term natural disaster has become an increasingly misnomer. Human behavior transforms natural hazards into unnatural disasters.” Most deaths from natural disasters occur in less developed countries. According to the United Nations, a less developed country (LDC) is a country that exhibits the lowest indicators of socioeconomic development and is ranked among the lowest on the Human Development Index . Those who live in low-income environments tend to have the following characteristics:

• Live in areas at a higher risk of geologic, weather, and climate-related disasters.
• They live in areas that lack the economics and resources to provide a safe living infrastructure for their people.
• Tend to have few social and economic assets and a weak social safety net
• Lack of the technological infrastructure to provide early warning systems

As human populations have grown and expanded, and technology has allowed us to manipulate the environment, natural disasters have become more complex and “unnatural.” Humans have not only influenced but magnified the impacts of disasters on society in numerous ways. For simplification, this book will narrow it down to four: human population growth, poverty and inequality, environmental degradation, and climate change.

In this article, we will Define Natural Calamities and Its Types with suitable examples.

What are Natural Calamities?

Natural Calamities, also known as natural disasters, are events or phenomena that occur in nature and can cause significant damage, destruction, and disruption to human lives, property, and the environment. These events are often unpredictable and are not caused by human activities.

Types of Natural Calamities:

1. atmospheric calamities:.

These are disasters related to the Earth’s atmosphere and weather conditions.

• Hurricanes or Cyclones: These are powerful storms with strong winds and heavy rainfall. They can cause extensive damage to coastal areas, leading to flooding and destruction of buildings and infrastructure.
• Tornadoes: These are rapidly rotating columns of air that can create a funnel-shaped cloud. Tornadoes are known for their destructive winds, capable of causing severe damage to everything in their path.

2. Hydrological Calamities:

These disasters are associated with water and the Earth’s hydrological cycle.

• Floods: Excessive rainfall, river overflow, or dam failures can result in floods. Floods can submerge large areas, damaging homes, crops, and infrastructure, and can cause loss of life.
• Droughts: Droughts occur when there is an extended period of significantly reduced rainfall, leading to water scarcity. Droughts can result in crop failure, livestock loss, and water shortages, impacting agriculture and communities.

Explain the following term Public Health.

Explain the need for People’s Participation in Environmental Conservation with suitable case studies.

How does the Environment Influence Human Health? Explain it in detail with suitable examples.

3. Geological Calamities:

These calamities are related to the Earth’s structure, including the crust, tectonic plates, and geological processes.

• Earthquakes: Earthquakes occur when there is a sudden release of energy in the Earth’s crust, causing the ground to shake. Earthquakes can cause buildings to collapse, landslides, and tsunamis if they occur near bodies of water.
• Volcanic Eruptions: Volcanic eruptions involve the release of molten rock, gases, and ash from volcanoes. They can cause ashfall, pyroclastic flows, and lava flows, which can lead to the destruction of surrounding areas.

4. Biological Calamities:

These disasters are associated with living organisms and can have impacts on human health and ecosystems.

• Epidemics/Pandemics: The rapid spread of infectious diseases among a population can lead to epidemics or pandemics. Examples include outbreaks of diseases like influenza, Ebola, or COVID-19, which can cause widespread illness, death, and strain on healthcare systems.
• Insect Infestations: Large-scale infestations of insects, such as locust swarms or bark beetles, can have severe consequences for agriculture, forests, and ecosystems, leading to crop losses and ecological imbalances.

These are just a few examples of natural calamities in different categories. Each type of calamity has its own characteristics and can pose significant challenges and risks to human lives, infrastructure, and the environment. Understanding these types can help in preparedness, mitigation, and response efforts to minimize the impact of such disasters.

• What are the different types of natural disasters? Give two examples of each.

Natural Disasters are catastrophic events that result from any of the Earth’s natural phenomena. These can range from floods and hurricanes to tsunamis and earthquakes.

The Earth, over its 4.54 billion-year history, has seen many natural disasters. Some of these disasters have led to several mass extinctions and drastic repercussions for various surviving species.

Natural Disasters Definition

A natural disaster can be defined as:

“A major event brought about by the natural processes of the Earth that causes widespread destruction to the environment and loss of life.”

A natural hazard often precedes a natural disaster. For instance, the Gujarat Earthquake, which occurred on 26th January 2001 is a natural disaster. The natural hazard is living under the active fault lines present under the state of Gujarat.

However, some natural hazards can also be provoked or affected by anthropogenic factors. For instance, landslides can be triggered by deforestation, mining and agricultural activities.

Natural disasters often cause destruction on a massive scale. Certain natural disasters such as wildfires cause destruction of animal habitat as well as damage to property and loss of life.

Natural Disasters List

There are many natural disasters. They can be grouped into different categories based on specific criteria:

Geological Disasters

Geological disasters are catastrophic events that arise as a result of changes in the earth, either above the surface or below the surface. For instance, volcanic eruptions frequently occur where tectonic plates make contact. Moreover, earthquakes are prone in regions with active plate tectonics.

Hydrological Disasters

Hydrological Disasters are described as a sudden and violent event caused due to the change in the quality, distribution or movement of water below the surface or in the atmosphere. For example, a tsunami is a large column of water or waves caused by the displacement of a large volume of water. They are generally caused due to earthquakes or volcanic eruptions under the sea.

Meteorological Disasters

Meteorological Disasters are usually caused by extreme weather such as rain, snow or drought. These affect the earth’s atmosphere and the weather-forming process. Moreover, these types of meteorological disasters are particularly destructive to the environment and can wreak havoc on life. Examples of meteorological disasters include hurricanes, hailstorms and tornadoes.

Space Disasters

Space disasters primarily include solar flares, impact events and airburst events. In the earth’s 4.5 billion-year history, impact events are believed to have caused at least one mass extinction. The KT extinction is the most credible – as there is circumstantial evidence in the form of the Chicxulub crater. This is also responsible for causing the extinction of all non-avian dinosaurs nearly 65 million years ago. Solar flares occur when the sun suddenly releases an unusually large amount of solar radiation. However, it is thought to not cause any direct effects on life – however, solar flares can damage electrical equipment, leading to disruption.

Gamma-ray bursts are extremely energetic explosions that are observed in distant galaxies. The Ordovician–Silurian extinction event, which occurred 450 million years ago on earth, is hypothesized to have been caused by a Gamma-ray burst. If such an event were to happen again today, it can result in a mass extinction event again.

Natural Disasters Examples

Nearly all the aforementioned types of natural disasters have occurred to date. A few of the most infamous natural disasters are discussed below:

Exploring the impact of natural disasters

Four of the five most costly natural disasters in our nation’s history have occurred during the past ten years. How has the government’s response to natural disasters changed? What is the impact of different types of disasters?

Updated on Thu, October 5, 2023 by the USAFacts Team

Hurricane Sandy, Hurricane Ike, Hurricane Maria, Hurricane Irma, and Hurricane Harvey. Four of the five most costly natural disasters in our nation’s history have occurred during the past ten years*. This is part of a larger pattern of the increasing frequency and impact of natural disasters.

How has the government’s response to natural disasters changed? What is the impact of different types of disasters?

Emergency response

Prior to the 1970s, there was no formal federal support for natural disasters. That changed after a wave of natural disasters in the 1960s and 1970s. In 1974, President Nixon passed the Disaster Relief Act , establishing the practice of Presidential disaster designations. In 1979, President Carter created the Federal Emergency Management Agency (FEMA) to coordinate emergency response efforts and national disaster preparedness planning.

The impact of disasters can be evaluated by a number of measures. Let’s look at frequency, cost, and the loss of human life.

FEMA tracks natural disasters over time. An analysis of the data shows that while the number of declared natural disasters was relatively low in the 1980s and 1990s, following the creation of the agency, the number of declared natural disasters has recently increased. Declarations increased from 31 in 1980 to 124 in 2018, a 300% increase.

Number of declared natural disasters

Severe storms

Not all natural events resulting in damage receive a declaration. What determines whether or not a declaration is made and how consistent is the declaration process?

The federal government has been making disaster declarations and providing support through FEMA funding since the 1970s. The decision to declare something an official disaster, and grant financial assistance to local governments, rests solely with the President. However, FEMA assesses the severity of the damage and the state’s ability to pay, and makes a recommendation to the President.

In addition, Congress reviews the process and makes legislative adjustments from time to time. For example, the Hurricane Sandy Recovery Improvement Act directed FEMA to update criteria used to make a recommendation to the President for an Individual Assistance declaration.

A 2014 Congressional Research Service report concludes that while the disaster declaration process has “changed very little over time,” it can be influenced by state’s understanding of how to craft a successful request, the presence of other funding or lack thereof, and the national narrative.

Each disaster is unique and the amount of damage caused varies widely. While FEMA does not publish complete spending per disaster, another agency, the National Oceanic and Atmospheric Administration, tracks the economic impact of costly disasters. These so-called “billion-dollar disasters” have been increasing in frequency and cost. Fourteen disasters caused more than $1 billion in damages in 2018, compared to 3 in 1980, after adjusting for inflation.

Cost of billion-dollar disasters

$24,000,000,000

Loss of human life

The deadliest disasters in recent history have been Hurricane Katrina and Hurricane Maria. Aside from these two events, the yearly number of deaths due to natural disasters has remained steady at less than 1,000 deaths per year.

Impact by disaster type

As noted above, hurricanes are the deadliest natural disasters. The most dangerous in recent history were Hurricane Maria in 2017, with 2,981 reported deaths, and Hurricane Katrina in 2005, with 1,833 reported deaths.

Hurricanes are also costly. Adjusting for inflation, 7 of the 10 most expensive natural disasters have been hurricanes. Of those 7, 6 have happened since 2000.

In the 1960s, the government began protecting the largest investments of Americans, their homes, from disaster.

The National Flood Insurance Program (NFIP) was created in 1968 to offer government insurance for homeowners with homes at risk of flooding. Beginning with 2 million policies in 1980, the program grew to 5 million covered homes by 2005. The number of covered homes has declined in recent years, from a high of 5,700,235 in 2009 to 5,133,785 in 2017.

While droughts do not have the same immediacy of impact as other disaster types, the economic damage can be significant. Low rainfall affects harvests and reduces crop production.

The US drought of 1988 led to the lowest crop harvest in the past 40 years. The 2012 drought affected more than 50% of the land area in the US, directly causing 123 deaths and resulting in $33 billion in economic damages. Crops like corn, soybeans, and sorghum experienced widespread failure.

Wildfires can be both part of the natural forest lifecycle and unexpected disasters as a result of human actions. Sometimes, they grow large enough to be declared natural disasters. While they are not the most deadly or costly, fires are the most frequent disaster affecting the United States.

In response to the large California wildfires of 2017 and 2018, caused by equipment from the utility company PG&E, the state of California created an insurance fund for utility providers. At the federal level, the Disaster Recovery Reform Act of 2018 signed by President Trump included expanded support for wildfire recovery.

The frequency and cost of declared natural disasters is increasing. The natural disasters with the most impact when assessing frequency, cost, and loss of life are hurricanes, floods, fires, and droughts.

Since the 1970s, the federal government has formalized planning and aid for natural disasters. Learn more about natural disaster spending by exploring data on before and after disaster spending.

Read Natural Disaster Essay on Vedantu

The planet earth has gone through many changes over these centuries. These changes are majorly due to natural disasters happening throughout time. When we talk about natural disasters, pollution, ozone depletion and global warming are the most common scenarios we witnessed.

Growing industrialisation and exploitation of natural resources have changed the echo system bringing on the verge of imbalance. However, over these decades, humans have also introduced many disaster warning systems helping to predict natural occurrence in advance. You can read more about Natural Disasters on Vedantu.

Different Faces of Natural Disasters

Nature possesses the character of a special balance in which all living beings live together in harmony with their environment. But whenever this balance is disturbed, we see the disastrous form of nature which wreaks havoc upon this world. Natural disasters come in various forms like earthquakes, Tsunami, Storms, Cyclones, droughts etc. These disasters have always occurred throughout history but the current threat of climate change has severely increased its risks. Man has to learn that he cannot control nature and his life should revolve around the conditions present in the environment and not the other way around.

We have tried to change the basic character of the Human-Nature relationship with every metric of development being centred on financial interest and the rise of global consumerism.  This way of life promotes greed and has fundamentally made human beings disoriented towards nature. Our festivals celebrate the intrinsic relationship between humans and the environment where we celebrate Mountains, Rivers, and Animals etc. Natural disasters are a reminder that humans must never take the gift of nature for granted and always reciprocate for the resources that we have received from the environment. Clean Air, Clean Water and harmony in the ecosystem is a prerequisite for Human well being.  

How to Deal with Natural Disasters?

India, due to its unique geographical character, faces natural disasters every year which cause massive harm to lives and property. Whether it be the floods of Uttarakhand in 2013 or the landslides in Western Ghats of Kerala. The cost of our blind exploitation of natural resources without showing reverence for the delicate balance of Nature has severely harmed us and we must learn lessons from these incidents.

One of the greatest stories of the Indian government in dealing with disaster readiness has been the story of the Indian state of Odisha. Odisha is a coastal state in eastern India that regularly faces cyclones that have caused great harm to the state. To deal with the menace of these cyclones the Odisha Government made an elaborate plan by taking the local communities in confidence and have successfully reduced the number of deaths in Odisha to a very small number which used to be in thousands earlier. Other Indian states should also learn from the experience of Odisha on how to improve disaster preparedness.

Keeping our environment safe and following the right process will help in bringing down the natural disasters. It is vital to learn about them.

FAQs on Natural Disasters Essay for Students in English

1.  What are natural disasters increasing?

Over the years, natural disasters have increased. Regular earthquakes, massive flooding, cyclones, etc. have increased. According to the office of US Foreign Disaster Assistance (OFDA) which maintains an emergency disaster database, if a natural disaster kills 10 people, then it leaves 100 people injured. Increase in hydro-meteorological disasters, the combination of natural and man-made factors is leading to an increase in natural disasters.

2. What are the natural disasters that happened in 2020?

From wildfires in the US to locusts attack in India and back-to-back cyclones in India, there are many natural disasters in 2020. According to the Global Catastrophe Recap’s First Half of 2020 report, there were more than 207 natural disasters in just the first six months of 2020, causing \[＄\]75 billion loss globally.

3. What natural disaster is the worst?

Every natural disaster causing the loss of both property and human lives is the worst. Be it the earthquake, wildfire or cyclone; each disaster can be the worst in its sense.

4. What are the causes of natural disasters?

Natural disasters are caused by a number of reasons which may or may not be linked to Human interference. Floods, for example, occur generally because of a sudden increase in water level which cannot be supported by the natural geography of the river, however, it has been observed that floods have also occurred due to human interference like encroachment of river banks, illegal sand mining and obstructions in the natural flow of the river. 

5. What are the agencies that deal with natural disasters?

On the National level, Natural disasters are dealt with by the National Disaster Relief Force or the NDRF. The NDRF has its own commissioned force which is highly experienced and trained to deal with situations when a disaster has occurred. Apart from the NDRF, there is also the SDRF which is present in every state. The central and state governments work in coordination during Natural disasters and saving lives along with restoration of normalcy is the primary concern of the relief operations.

6. What are the ways to deal with floods and droughts?

It may sound surprising to some people but India is a unique country where due to its vast geography, we have seen conditions where some parts of the country are facing floods while other parts suffer from drought in the same year. These are especially tough to deal with as the volume of water in floods just cannot be stored and once a region is facing drought, access to water becomes a question of survival. Linking rivers is a very grand scheme which can solve some of our problems but this also needs to be dealt with caution.

7. What can I do to contribute to disaster relief programmes?

The central and state governments carry out various programmes which are directly related to disaster relief work, coordinating with the agencies and donating to these relief operations are some things that we can do as citizens. There are various NGOs that provide relief material to people who are suffering from natural disasters. Creating awareness about such an important issue is also an essential activity. You can learn more about it on Vedantu website and download it in PDF format.

8. Which regions are the most affected by natural disasters in India?

Every part of the country has a unique geographical character and in some way or the other, they face the threat of natural disasters. Bihar and Assam are two such states which face floods on an annual basis, The Himalayan states have a very delicate ecology and save the menace of flash floods and landslides. Maharashtra has a problem of flooding in the Western Ghats while Vidarbha faces drought. Innovative ways must be discovered by states to deal with natural disasters.

Natural Disasters- Cause and Effects

Natural disasters as we all know are the consequences of events triggered by natural hazards that overwhelm local response capacity and seriously affect the social and economic development of a region. There is basically no human control over the natural disaster. We cannot stop these natural disasters but what is in our hands is to be prepared for these. Also, there are a lot of ways through which we can minimize the damage caused due to these natural disasters. Traditionally, natural disasters have been seen as situations that create challenges and problems mainly of a humanitarian nature. There is no way to prevent or avert these natural disasters, though scientists do claim to have found the ways to predict these natural disasters at most of the times they have failed to predict natural disasters causing some serious destruction.

During the last few years, there has been an increase in the reports of natural disasters as well as destruction caused due to these disasters. The tsunamis, hurricanes and earthquakes, which hit parts of Asia and the Americas in 2004/2005 are some examples of natural disasters in past few years and floods in the parts of Uttarakhand is a recent example of the destruction caused due to these natural calamities. These calamities have led to the displacement of a lot of people and heavy loss of life as well as the property was also reported. Not just these few cases, natural disasters can be of many types which may include volcanic eruptions, tsunamis, floods, drought, landslides, or earthquakes etc.

From past many years, there has been a constant debate on the topic of natural disasters and the human role in the same. A lot of human practices, as well as rapidly growing developmental activities, have been blamed for the constant rise of these natural disasters like floods, hurricanes and tsunamis in past few years. One of the major causes of natural disasters has been attributed to the global warming, which has sparked debate analyzing what the effects may be. The reality at present is that we are experiencing an increasing number of natural disasters, and disaster preparedness is an area still to develop. Also along with the disaster preparedness, there is a need to keep a check on developmental activities so that we could have a sustained environment.

Types of Natural Disasters

The natural disaster is the consequence when a natural hazard affects humans in an adverse manner. Human vulnerability, caused by the lack of appropriate preparedness often leads to financial, environmental, or human impact in a negative manner. A natural disaster always brings along loss of life and property damage, and typically leaves economic damage in its wake, the severity of which depends on the intensity of the disaster. At times there can be some minor losses only whereas human life has also witnessed few disasters that have caused a major loss of life and property as well.

The resulting loss due to a natural disaster also depends on the capacity of the population or authorities to support or resist the disaster as well as emergency preparedness. This understanding is concentrated in the formulation: "disasters occur when hazards meet vulnerability". A natural hazard will hence never result in a natural disaster in areas without vulnerability, e.g., strong earthquakes in uninhabited areas. The term natural has consequently been disputed because the events simply are not hazards or disasters without human involvement. Different types of natural disasters can be:

• Earthquakes
• Forest fires
• Thunderstorms
• Winter storms

Causes of Natural Disasters

• There are different types of natural disasters and depending on different types of disasters the causes are also different. For example, the causes of an earthquake cannot be the same as that of forest-fire. Natural disasters are caused due to different reasons like soil erosion, seismic activity, tectonic movements, air pressure, and ocean currents etc. natural disaster is not a new phenomenon these natural events have occurred since the earth began forming and continue to cause serious damage and loss of life all over the globe from many years. The root causes of most of the natural disasters that occur on earth can be attributed to the imbalance created in our environment. This imbalance may either be in the form of air pollution, noise pollution or water pollution and the collective effect of these imbalances are also one of the few reasons for the natural disaster. Though it also a fact that we cannot blame anyone because this is just one of the few reasons. Natural disasters like earthquake, floods etc have also occurred in past era when the human was far away from modernization. So it would not be fair enough to blame modernization for the same.
• Natural activities taking place in the earth’s crust, as well as surface, are the main reasons for these disasters. Seismic activity caused by earthquakes have been the root cause of volcanoes erupting and typhoons. It has been studied that the continents sit on huge plates that occasionally shift and when these plates shift they cause an increase in pressure underneath the earth’s surface which is also a cause of natural disasters. Tectonic movements in the earth’s crust are responsible for the earthquakes, which at times can get really dangerous and may lead to some heavy loss of life and property. In areas where volcanoes have formed by solidified magma, pressure from gasses and magma can explode or erupt to send tons of ash into the atmosphere.
• The activity of the moon determines the ocean waves which can get really high during the full moon and at times these can be really dangerous. It was also observed that deadly December 2004 tsunami also occurred on a full moon night. The earthquake was caused when the Indian Plate was subducted by the Burma Plate and triggered a series of devastating tsunamis along the coasts of most landmasses bordering the Indian Ocean, killing over 230,000 people in fourteen countries, and inundating coastal communities with waves up to 30 meters (98 ft) high. It was one of the deadliest natural disasters in recorded history. Indonesia was the hardest-hit country, followed by Sri Lanka, India, and Thailand.
• Changing ocean currents are also dangerous at times and can result in changes in water temperature which could result in a global food shortage by killing fish and ocean plant life. These changing oceanic currents could also adversely affect the intensity as well as the frequency of storms. Tornadoes which are really dangerous are often formed by the interaction of high and low-pressure air and these have proved to be really dangerous as well as devastating for many communities in the area of America, especially the area of Tornado Alley. Air pressure, high and low determines whether or not we have thunderstorms, rain and hurricanes. Flooding and high winds are caused by the crashing together of low and high-pressure air. Damage caused by flooding and hurricanes along coastal cities and towns can be really difficult to overcome for their victims.
• Natural Disasters are a set of naturally occurring events which can directly or indirectly cause severe threats to human health and well-being and adversely affects the human life for quite some time. It has been witnessed that the natural disasters have their root causes in the normal activities of the earth. However during the past few years, we have witnessed some rapid modernization and growth, man's increased knowledge and technology has served to trigger for some natural disasters. Flooding and erosion can occur are really prone to the areas where mining, deforestation, and manufacturing have taken place. Global warming, which could eventually affect the ocean currents, has its roots in modern man's overuse of fossil fuels. Earthquakes resulting as a result of tectonic movements and movements of plates inside the earth’s crust can also be triggered by drilling, bombing, mining, and construction.

The Impact of Human Activities on Natural Disasters

• It has been estimated that rapidly growing modernization is leading to ignorance towards the environment. Today we are growing at a rapid rate neglecting the harm that we are causing to our environment. Environmental bylaws are being neglected for personal gains by few businessmen. The dual forces of global warming, as well as poor human management in the field of land and water resources, combine to the cause of natural disasters. Humans have created a situation where ordinary events like earthquakes and hurricanes become increasingly elevated to the level of natural disasters which results in heavy losses in the terms of human life as well as property.
• Scientists researching on this topic from past many years have found that the increase in hydro-meteorological disasters can be attributed to a combination of natural and human-caused factors. The main problem is global warming which is increasing the temperatures of Earth's oceans and atmosphere, leading to more intense storms of all types, including hurricanes and floods due to the melting of these oceans. Unplanned urbanization is at its peak, no one is really caring about the environmental risks and everyone is busy making money. There are a lot of constructions coming up in flood-prone regions which have increased the likelihood that their towns and villages will be affected by flash floods and coastal floods. A recent flood in Uttarakhand is one such example. Human greed is increasing day by day and people are not at all hesitant in ignoring the environmental laws and result is the destruction.
• In one way or the other we are hampering our environment, the rapidly growing industrialization has led to a lot of air as well as water pollution. Though there are environmental laws that these industries need to follow to treat the waste before disposing of into the environment but most of the times the industry owners neglect these laws for their personal gain and even authorities are also quite relaxed and do not take a prompt action against the culprits. Rapid construction has led to large land areas being covered with cement, which means that the flow of water becomes very strong, and the runoff from the water can't get absorbed by the soil anymore, so it keeps collecting and rushing down, getting heavier and faster, which may ultimately lead to much bigger floods.  
• It is not that everyone is being ignorant in the race to be the best. There are also a lot of people who really care about the environment and are really serious about taking up the matter at a larger scale. There are many societies and group of people who are working in the field of environmental awareness and are working day and night out to make people aware of the harmful effects of the pollution and other practices that are harmful to our environment. Several NGO’s are taking up the issue of pollution and global warming publically by taking out rallies and organizing various campaigns to save the environment and such initiatives need to be appreciated.

Prevention and Control On Natural Disaster

• Natural disasters are inevitable, even if we have the technology to predict disasters we cannot stop it from occurring. The best that we can do is to stop the practices that are harmful to our environment and leading to environmental degradation and at the same time, we should also be prepared for a disaster with our disaster management plan. Beyond damaging and destroying physical infrastructure, natural disasters can lead to outbreaks of infectious disease. Once a disaster strikes it leaves behind a lot of destruction and loss of life. In the case of disasters like floods, earthquake etc. where a large number of people are displaced there is also a great loss of life and after the disaster, there are a lot of causalities also. This is the time when emergency preparedness comes into effect giving first aid to injured and providing rescue and relief operation.
• The overwhelming majority of deaths immediately after a natural disaster is directly associated with blunt trauma, crash-related injuries and burn injuries. The risk of infectious disease outbreaks in the aftermath of natural disasters has usually been overemphasized by health officials and the media, leading to panic, confusion and sometimes to unnecessary public health activities. After a disaster strikes there is a great risk of epidemic hence it is very important to control the causalities as well as it is also required to dispose of the dead animals as well human bodies properly before an epidemic outbreak.
• The risk factors for increased infectious diseases transmission and outbreaks are mainly associated with the after-effects of the disasters rather than to the primary disaster itself or to the corpses of those killed. It is very important to deal with these problems which in turn can pose a greater threat. These after-effects include displacement of populations, environmental changes and increased vector breeding sites. Unplanned and overcrowded shelters, poor water and sanitation conditions, poor nutritional status or insufficient personal hygiene are often the cases which may cause diarrhoea and other water-borne diseases. Consequently, there are low levels of immunity to vaccine-preventable diseases, or insufficient vaccination coverage and limited access to health care services. Hence it is very important to be prepared with a proper disaster management team who can take charge as soon a disaster strikes.

Bibliography

Deforestation can be investigated and quantified at the environmental level as a land use change or the cumulative effect of multiple human activity changes. However, the pressures, agents, and relationships that drive deforestation create a complicated network that is dynamically changing throughout time 1 . Therefore, the factors influencing deforestation can be triggered by either human activities or purely environmental factors 2 . The rationale that human activities, such as clearing land for agriculture and industrialization, are the sole cause of deforestation is biased, considering that some factors, including natural calamities, can be justified as direct causes of deforestation.

Deforestation is a significant challenge in promoting a sustainable ecosystem, considering it reduces the quality of nature, human life, and well-being. Deforestation causes habitat destruction and biodiversity degradation since trees are cut down without much regeneration. Additionally, it lowers living standards due to increased wood consumption for industrial and fuel purposes 3 . Various works of literature have established that human activities, including cutting down trees for domestic use and clearing the land for industrialization, promote deforestation 4 . However, little is known about natural disasters’ influence on promoting deforestation 5 . For instance, the effects of forest fire, acid rain, storms, and flooding have not been extensively addressed. Through qualitative research on research findings, this study reveals how natural storms, forest fires, acid rains, and flooding cause deforestation.

• What is the effect of natural storms on rainforests?
• How forest fire affects sustainable rainforests?
• How do acid rain and flooding cause deforestation?
• What are some of the natural calamities that destroy rainforests?

The main goal of this study is to establish a new concept explaining the influence of natural calamities on deforestation. This idea will single out the human activity as the leading cause of deforestation. The study will also provide evidence on how natural disasters derail efforts in reforestation.

Human activities have been cited as the primary cause of deforestation. The conversion of forest land to tropical agriculture is one cause of deforestation, considering that the activity results in permanent forest damage 6 . This human activity has depleted rainforests due to the need for constant demand for agricultural produce. When rainforests are cleared for agricultural activities, none of the trees harvested is replanted, reducing available trees.

Another human activity influencing deforestation is making rainforest lands available for housing and urbanization practices. The development of infrastructure and industries has accelerated deforestation, considering that more trees are cut down to create land for urbanization 7 . All these factors indicate that human activities have significantly affected the sustainability of rainforests, accelerating deforestation.

One pertinent issue supporting the dominance in deforestation includes the burning of land, whereby some trees are burned to maintain the health of the rainforest. Sometimes, the need for land for cultivation or industrial purposes could lead to uncontrolled burning, resulting in deforestation 8 . All these factors indicate that human activities have detrimental effects on the sustainability of rainforests. Most of these researchers have dwelt on the direct causes of deforestation, sidelining other indirect effects such as natural disasters.

The research methods will include qualitative research strategies, including questionnaires and literature review since both will explain how the different variables interrelate to provide a specific result. The study will identify the dependent and independent variables using the results obtained from the survey and literature. This strategy will ensure that classification of the different variables and how they influence one another is done with zero constraints. The sample population for this study will be adults between the ages of 30-45 years. These indigenous people residing within the rainforests or working with forest protection organizations and those concerned about climate change will be important to the study. These volunteers will fill in the questionnaire, which will be analyzed using the summary of the major trends. The sample size is 100 human participants from diverse backgrounds or expertise in rainforest conservation. The study will be conducted for 30 days to ensure that the data collected is convincing enough to justify an argument.

Some materials needed for analyzing questionnaire results include score sheet templates and data analysis tools such as Microsoft Excel, which will help analyze the different trends identified so that an objective result can be tabulated.

Limitations- The small sample size in this research could result from a lack of sufficient evidence to support the issue of deforestation or direct influences. Another significant factor is a restricted timeline, considering deforestation is a global researchable phenomenon.

This research aims to highlight how natural calamities influence deforestation through rainforest destruction. Through qualitative research designs, the study will analyze some of the existing literature and analysis of the questionnaire results to determine the effects of natural disasters such as flooding and the destruction of trees. All these data findings will be analyzed and tabulated to show how each of the mentioned variables affects the sustainability of rainforests.

Engineering Connection

Engineers learn about our planet so that humans can exist with and survive its powerful natural forces. Engineers must be aware of natural hazards in order to prevent or minimize their harmful effects on people and property. By creating improved techniques and materials, engineers make sure the structures we rely upon are built strong enough to reduce human injuries and casualties from the tremendous natural forces of wind, snow, water, fire and moving earth. While most natural hazards cannot be prevented, engineers do their best to create data gathering, monitoring, measuring, prediction and warning equipment, tools and models to protect human populations. Engineers use their science and math skills to build instruments and computer programs that can detect gases, changes in the shape of volcanoes, monitor underground movement, and estimate storm locations and severity. Data is collected by cameras, seismometers, GPS, pressure sensors, radar and satellites. Other helpful technologies include avalanche beacons and airbags, lightning rods, building shock absorbers and sliders, and warning sirens. Engineers work with scientists to determine locations at which dangers exist, how to minimize risks, and how to prevent the actions of people from creating catastrophes. Engineers also design test facilities to simulate and study hazard characteristics and model scenarios with computer simulations. Engineers also analyze and learn from past failures as a way to continue to improve structural designs, advance warning systems and emergency procedures for human safety. As engineers create devices that detect natural hazards, build structures to withstand them, and invent devices to study them, they use the process of gathering and analyzing data to better understand problems and formulate solutions.

What is a Natural Disaster? Types, Causes, Events

• Updated on  
• Apr 5, 2023

Natural disasters refer to hazardous activities damaging both resources and lives. There are different types of natural disasters such as floods , storms, tsunamis, earthquakes, etc. Over the course of its billions-year history, the earth has seen several natural disasters . Several mass extinction events and severe consequences for various surviving species have resulted from some of these events. To find the answer to this and more details on Natural disasters, here is a blog that will explore everything!

This Blog Includes:

What is natural disaster, geological disasters, meteorological disasters, hydrological disasters, biological disasters, other disasters.

A natural disaster can be defined as “A major event caused by Earth’s natural processes that leads to significant environmental degradation and loss of life.” A natural disaster is frequently preceded by a natural hazard. The Gujarat Earthquake, for example, which struck on January 26, 2001, was a natural calamity. The natural danger lives underneath the active fault lines that run through Gujarat .

Anthropogenic causes, on the other hand, can cause or affect some natural dangers. Deforestation, mining, and agricultural activities, for example, can all cause landslides . Natural disasters frequently result in widespread damage. Natural disasters, such as wildfires, destroy animal habitats while also causing property damage and loss of life.

Types of Natural Disasters

Geological Disasters, Hydrological disasters, Meteorological Disasters, and Biological Disasters are the four broad types of natural hazards.

Geological hazards, or dangers caused by geological (i.e., Earth) processes, such as plate tectonics, are a type of risk. Earthquakes and volcanic eruptions are examples of this. In general, geological extreme events are beyond human control, however, humans have a significant impact on the events’ consequences.

Also Read: Public Facilities Class 8

Hazards caused by meteorological (i.e., weather) phenomena, particularly those related to temperature and wind, are known as meteorological hazards. Heat waves, cold waves, cyclones, hurricanes, and freezing rain are all examples of this. In the Atlantic, cyclones are known as hurricanes, while in the Pacific, they are known as typhoons.

Also Read: Class 8 The Indian Constitution

Hazards caused by hydrological (water) processes are known as hydrological hazards. Floods, droughts, mudslides, and tsunamis are examples of natural disasters. Floods and droughts may cause havoc on agriculture and are one of the leading causes of famine. The 1931 Central China floods killed three or four million people, making it the greatest natural disaster in history(excluding pandemics).

Also Read: Understanding Secularism Class 8 Notes

Biological dangers are those that arise as a result of biological processes. This comprises a wide range of diseases, including infectious diseases that move from person to person and pose a significant threat to vast populations of people. Biological hazards are often left out of discussions about natural hazards, instead of falling under the purview of medicine and public health.

Now that we have studied the classification of Natural Disasters let us look into some Natural Disasters in depth. 

Tornadoes are rotating, funnel-shaped clouds that form as a result of intense thunderstorms. With powerful winds averaging 30 miles per hour, they extend from a thunderstorm to the ground. They can also go from being stationary to 70 miles per hour in a matter of seconds.

Tornadoes can strike with little or no notice, giving those in affected areas only seconds to seek shelter. People often endure emotional anguish as a result of the unexpected nature of tornadoes and severe storms. Overwhelming anxiety, difficulty sleeping, and other depression-like symptoms are common reactions to natural disasters.

Tropical storms that originate in the southern Atlantic Ocean, Caribbean Sea, Gulf of Mexico, and the eastern Pacific Ocean are known as hurricanes. Every year, hurricanes harm millions of people living along the Atlantic and Gulf coasts. Hurricanes are known to cause mental suffering in their victims. Before, during, and after these types of storms, people commonly experience intense anxiety, continual worrying, difficulty sleeping, and other depression-like symptoms. Other symptoms of hurricane-related emotional distress include:

Fearing that forecasted storms could turn into hurricanes, even if the chances of this happening are slim, yelling or fighting with family and friends on a regular basis Having storm-related thoughts, memories, or dreams that you can’t seem to get out of your head.

Floods happen when water overflows from an area that is ordinarily dry. Floods are caused by a variety of factors, including hurricanes and tropical storms, broken dams or levees, and flash floods that happen within minutes or hours of heavy rain. Although floods are more common around the shore, especially during hurricane season, they can happen anywhere and vary in magnitude and length. Even little streams, gullies, and creeks that appear to be unaffected in dry weather might become flooded. Here are some symptoms of emotional discomfort caused by floods:

If you’re feeling hopeless or helpless, Fearing that anticipated storms would turn into hurricanes, even if the chances of this happening are slim, yelling or fighting with family and friends on a regular basis.

An earthquake occurs when the Earth’s plates shift, causing a violent shaking of the ground that can last anywhere from a few seconds to several minutes. Mild initial shaking might quickly intensify and become violent. Earthquakes are quite common, and they happen every day somewhere in the world. Even mild earthquakes that cause minor damage and destruction can induce emotional discomfort in people (especially in areas not accustomed to these events). Aftershocks can occur for months after an earthquake, and they can be just as distressing. Here are some symptoms of emotional distress caused by earthquakes:

Being easily startled, having trouble sleeping or sleeping too much, and having thoughts and memories of the earthquake that you can’t shake

A drought is a common, recurring meteorological occurrence that varies in intensity and duration depending on the region of the country and even within a state. Drought occurs when precipitation is below average for an extended period of time, usually a season or more. Drought can also be caused by a delay in the rainy season or rain timing in relation to crop development. Some symptoms of drought-related emotional discomfort include:

Feelings of overwhelming anxiety, continual worrying, difficulty sleeping, and other depressive-like symptoms, disagreements between people over limited water supplies, health issues connected to dust, insufficient water flow, or poor water and air quality, and financial problems due to crop failures

Examples of Natural Disasters

Here given below are the some examples of natural disasters-

• Avalanche : An earthquake triggered an avalanche in Peru, killing nearly 20,000 people in 1970.
• Landslides : An entire village was wiped away in the Pithoragarh district of Uttarakhand in 1998.
• Earthquakes : An earthquake which registered 7.9 on the Richter scale, ripped through Gujarat, killing over 1,00,000 people in 2001.
• Sinkholes : A sinkhole over 100 meters deep formed suddenly. The event resulted in the death of five people and the evacuation of thousands in 2007.
• Volcanic Eruption : Mount Vesuvius – the deadliest volcano to ever erupt. It released 100,000 times the thermal energy of the Hiroshima-Nagasaki bombings. It was speculated that around 2,000 people died as a direct result in 79 AD.

• Flood : A series of floods devastated China in 1931. It was also called one of the deadliest floods in history, with the death toll estimated to be between 3.7 million to 4 million.
• Tsunami : A 9.0 magnitude earthquake caused a 33-foot-high tsunami to strike in 2011. It resulted in the deaths of over 18,500 individuals. The tsunami also caused the nuclear meltdown of the Fukushima Nuclear Power Plant.
• Limnic Eruption : A limnic eruption was a rare kind of natural disaster in 1986. Because of its invisible nature, only two instances of this disaster have been ever observed. The deadliest among the two was the Lake Nyos limnic eruption. 1746 people and 3500 cattle were killed in this event.
• Cyclonic Storm : Cyclone Amphan caused widespread damage in Eastern India, while Cyclone Nisarga wreaked havoc on the West Coast of India in 1920.
• Blizzard : In 1972, a blizzard dropped nearly 26 feet of snow, completely covering 200 villages in Iran. It was the deadliest in recorded history, causing the death of 4,000 individuals.
• Cold waves : In February 2020, Baghdad experienced the very first snowfall since the 1910s.
• Drought : Cape Town, in South Africa, faced a major water crisis between 2017 to 2018. This crisis had an extensive impact on public health and the nation’s economy.
• Tornadoes: The Daulatpur-Saturia tornado was the deadliest tornado to occur in recorded history. It killed approximately 1,300 people and injured an estimated 12,000 people

Forest fires: The 2019-20 Australian Bushfires resulted in 34 deaths, the destruction of 5,900 buildings, and an estimated 46 million acres were burnt.

Over the centuries, earthquakes have been responsible for millions of deaths and an incalculable amount of damage to property. Depending on their intensity, earthquakes (specifically, the degree to which they cause the ground’s surface to shake) can topple buildings and bridges , rupture gas pipelines and other infrastructure, and trigger landslides , tsunamis , and volcanoes .  These phenomena are primarily responsible for deaths and injuries. Very great earthquakes occur on average about once per year.

Earthquake waves, more commonly known as seismic waves , are vibrations generated by an earthquake and propagated within Earth or along its surface. There are four principal types of elastic waves: two, primary and secondary waves, travel within Earth, whereas the other two, Rayleigh and Love waves, called surface waves, travel along its surface. In addition, seismic waves can be produced artificially by explosions.

Magnitude is a measure of the amplitude (height) of the seismic waves an earthquake’s source produces as recorded by seismographs . Seismologist Charles F. Richter created an earthquake magnitude scale using the logarithm of the largest seismic wave’s amplitude to base 10. Richter’s scale was originally for measuring the magnitude of earthquakes from magnitudes 3 to 7, limiting its usefulness. Today the moment magnitude scale, a closer measure of an earthquake’s total energy release, is preferred.

Earthquakes can occur anywhere, but they occur mainly along fault lines (planar or curved fractures in the rocks of Earth’s crust ), where compressional or tensional forces move rocks on opposite sides of a fracture. Faults extend from a few centimetres to many hundreds of kilometres. In addition, most of the world’s earthquakes occur within the Ring of Fire , a long horseshoe-shaped belt of earthquake epicentres , volcanoes , and tectonic plate boundaries fringing the Pacific basin .

Recent News

earthquake , any sudden shaking of the ground caused by the passage of seismic waves through Earth ’s rocks. Seismic waves are produced when some form of energy stored in Earth’s crust is suddenly released, usually when masses of rock straining against one another suddenly fracture and “slip.” Earthquakes occur most often along geologic faults , narrow zones where rock masses move in relation to one another. The major fault lines of the world are located at the fringes of the huge tectonic plates that make up Earth’s crust. ( See the table of major earthquakes.)

Little was understood about earthquakes until the emergence of seismology at the beginning of the 20th century. Seismology , which involves the scientific study of all aspects of earthquakes, has yielded answers to such long-standing questions as why and how earthquakes occur.

About 50,000 earthquakes large enough to be noticed without the aid of instruments occur annually over the entire Earth. Of these, approximately 100 are of sufficient size to produce substantial damage if their centres are near areas of habitation. Very great earthquakes occur on average about once per year. Over the centuries they have been responsible for millions of deaths and an incalculable amount of damage to property.

The nature of earthquakes

Causes of earthquakes.

Earth’s major earthquakes occur mainly in belts coinciding with the margins of tectonic plates. This has long been apparent from early catalogs of felt earthquakes and is even more readily discernible in modern seismicity maps, which show instrumentally determined epicentres. The most important earthquake belt is the Circum-Pacific Belt , which affects many populated coastal regions around the Pacific Ocean —for example, those of New Zealand , New Guinea , Japan , the Aleutian Islands , Alaska , and the western coasts of North and South America . It is estimated that 80 percent of the energy presently released in earthquakes comes from those whose epicentres are in this belt. The seismic activity is by no means uniform throughout the belt, and there are a number of branches at various points. Because at many places the Circum-Pacific Belt is associated with volcanic activity , it has been popularly dubbed the “Pacific Ring of Fire .”

A second belt, known as the Alpide Belt , passes through the Mediterranean region eastward through Asia and joins the Circum-Pacific Belt in the East Indies . The energy released in earthquakes from this belt is about 15 percent of the world total. There also are striking connected belts of seismic activity, mainly along oceanic ridges —including those in the Arctic Ocean , the Atlantic Ocean , and the western Indian Ocean —and along the rift valleys of East Africa . This global seismicity distribution is best understood in terms of its plate tectonic setting .

Natural forces

Earthquakes are caused by the sudden release of energy within some limited region of the rocks of the Earth . The energy can be released by elastic strain , gravity, chemical reactions, or even the motion of massive bodies. Of all these the release of elastic strain is the most important cause, because this form of energy is the only kind that can be stored in sufficient quantity in the Earth to produce major disturbances. Earthquakes associated with this type of energy release are called tectonic earthquakes.
