natural disaster, any calamitous occurrence generated by the effects of natural, rather than human-driven, phenomena that produces great loss of human life or destruction of the natural environment, private property, or public infrastructure. A natural disaster may be caused by weather and climate events or by earthquakes, landslides, and other occurrences that originate at Earth's surface or within the planet itself. No spot on Earth is immune from a natural disaster; however, certain types of disasters are often limited to or occur more frequently in specific geographic regions.

Types

Weather- and climate-driven natural disasters include flooding caused by heavy rains associated with hurricanes and typhoons ( tropical cyclones) and other intense storms; drought, famine, and wildfires brought on by heat waves and shifts in precipitation patterns; wind-generated devastation caused by tropical cyclones, tornadoes, derechos, and other windstorms; and damage and loss of life caused by blizzards and heavy snowfalls. Earth-driven natural disasters include large volcanic eruptions (which produce lava flows, explosions, toxic gas clouds, ash falls, and pyroclastic flows that damage populated areas) and strong earthquakes (which result from the sudden fracturing of Earth's crust) powerful enough to damage or destroy built-up areas near their origin points.

Some phenomena that produce natural disasters may be caused by a combination of several different forces. For example, landslides (the movement of large masses of rock, debris, and soil downslope) may be caused by rains that saturate the soil on an unstable slope, or they may be triggered by earthquakes. In a similar manner, the buildup of snow on mountain slopes increases the risks of localized avalanches. Tsunamis, catastrophic ocean waves that can rise as high as 30 metres (about 100 feet) above normal sea level, are produced by submarine earthquakes, underwater or coastal landslides, volcanic eruptions, or meteor or comet impacts. The largest tsunamis are fast-moving waves that can travel across oceans to wreak havoc in coastal areas separated thousands of kilometres from one another.

Frequency and disaster patterns

Certain types of natural disasters are more likely to occur in specific geographic regions, and in some places these events occur with seasonal regularity, as in the spring tornado season in the United States or the summer-and-fall hurricane season in the Atlantic Ocean, Caribbean Sea, and the Gulf of Mexico. Earthquakes and volcanic eruptions are most frequent near tectonic plate boundaries, and an especially active boundary exists between the Indo-Australian and Eurasian plates.

The World Meteorological Organization (WMO)-a United Nations (UN) agency that monitors Earth's land, water, and atmosphere-reported in 2021 that the number of natural disasters per decade showed a fivefold increase from 1979 to 2019, and data collected in the EM-DAT, an international disaster database maintained by the Center for Research on the Epidemiology of Disasters, Brussels, indicate that more than 300 disasters have been tallied each year since 1998. Though many natural disasters are neither preventable nor largely predictable, the WMO report notes that global warming-an increasingly human-driven phenomenon generated by the emission of greenhouse gases, specifically those released by the combustion of fossil fuels-is increasing the frequency of weather- and climate-related natural disasters, such as droughts, heat waves, increasingly intense hurricanes, and flooding due to sea-level rise. Warmer temperatures are causing more extreme weather events by delivering more precipitation to some areas-which may be unused to receiving heavy rains and snows, increasing flooding risk-while delivering less to other areas that rely on it, increasing drought risk. In addition, reliable sources of rainfall, such as the South Asian monsoon, on which agriculture of the Indian subcontinent has long depended, are becoming less predictable, and rain events have become more violent and dangerous, damaging crops and producing more intense flooding. This change has subjected some areas under the monsoon's influence to extended drought conditions, whereas other areas receive too much rainfall, a pattern that scientists predict will worsen in the 21st century.

Damage and deaths

The costs of individual natural disasters frequently reach the tens of billions of dollars. Such costs may be associated with damage to crops, buildings, and infrastructure that occurs annually in areas prone to tropical cyclone activity or heavy seasonal rains, with some events, such as the Pakistan floods of 2022 and Hurricane Katrina (which struck the southern United States in 2005), costing more than $30 billion and $186 billion, respectively. Similarly, costs associated with earthquakes, which occur less regularly, can be high (such as China's Sichuan earthquake of 2008 and Japan's Kōbe earthquake of 1995, which incurred costs estimated at more than $86 billion and more than $100 billion, respectively).

The number of deaths from natural disasters also varies by location and the intensity of the event; however, the overall trend points to a decline from several hundreds of thousands of deaths annually during the first half of the 20th century to roughly 45,000 deaths globally each year. The number of deaths also varies widely from year to year, with smaller natural disasters (or natural disasters occurring in areas far from human settlement) killing few and shockingly large disasters producing truly massive losses of life. Some of the most notable catastrophic disasters in history include the Indian Ocean tsunami of 2004 (which killed more than 225,000 people), the Tangshan earthquake of 1976 (which resulted in more than 242,000 deaths), the 2010 Haiti earthquake (which by some estimates may have killed at least 300,000 people), and China's Shaanxi province earthquake of 1556 (which killed more than 800,000 people).

Although deaths from natural disasters have decreased overall, people in lower-income countries often suffer disproportionately, because these locations have fewer resources and thus greater vulnerability to the elements and to food insecurity. In contrast, highly developed countries have better infrastructure (for communications, evacuation procedures, the movement of resources, and the delivery of medical services). In addition, high-income countries can implement policies that limit construction in flood-prone areas or mandate the construction of more earthquake-resistant homes, office buildings, and other structures, thereby reducing the risk of crushing injury and death stemming from building collapses. Consequently, relatively few people die from earthquakes in California, a location well-known for its strong building codes with respect to withstanding earthquakes, compared with places such as Iran and Pakistan, where building codes are either less stringent or whose codes frequently go unenforced.

Disaster warning systems

Advances in weather forecasting and advances in land-based seismic sensors and sensors placed aboard satellites, aircraft, and stationary buoys floating in the world's oceans have led to the development of various kinds of early warning systems. In some cases, these systems are capable of predicting or accurately classifying the strength of the physical forces that generate natural disasters before they cause damage. The perhaps most widespread and best known of these systems are those used by national weather bureaus that classify, track, and predict various weather events and issue bulletins about storms and other weather and climate phenomena affecting their land areas and sea zones. National weather bureaus are often made up of a network of numerous local offices spread across a country that gauge local weather conditions several times per day. Data collected by these offices can be used to develop weather models that help to predict the strength of a storm, as well as its location, days in advance of its arrival in a local area.

In addition, specialized units within national governments-such as the China Earthquake Administration, the Japan Meteorological Agency, the United Kingdom's Met Office, India's National Center of Seismology, the U.S. National Oceanic and Atmospheric Administration, and the U.S. Geological Survey-monitor specific physical forces capable of causing the most damaging and deadly natural disasters (that is, earthquakes, tsunamis, droughts, flooding, and winds driven by tornadoes and tropical cyclones). Many of these organizations within specific countries cooperate with their counterparts in others or assist international organizations, such as the WMO and the International Tsunami Information Center, to issue warnings, develop international safety standards, and assess the risks associated with forces that affect several countries or the planet as a whole. Some early warning systems even look beyond Earth's atmosphere; the near-Earth objects system operated by the European Space Agency and the Scout and Sentry impact hazard systems run by NASA in the United States are a few of several systems designed to detect, track, and predict the risk associated with asteroids, comets, and other extraterrestrial objects capable of striking Earth.

Recently, we have been investigating some of Earth's most destructive forces by exploring natural disaster science activities! No matter where you live, you have probably had to brace or prepare for a natural disaster in your lifetime. For instance, because we live in California, earthquakes are always going to be at the forefront of our news cycle. Those of you on the East Coast know that hurricanes are a possibility every year. Teaching children about how and why these disasters occur is very important. We find that discussing ways to prepare and stay safe takes some of the fear out of these situations.

One way to introduce natural disasters to your science curriculum is to give your students the opportunity to observe these forces with actual hands on science experiments. They get to see science in action instead of just reading about it! The four activities we are about to share with you can all be easily done in both the home and classroom setting. Best of all, you probably have most of the materials already! They can be done before or after introducing natural disasters to your little scientists.

Natural Disaster Science Activities

1. Tornado in a Jar
What You Need:

clear plastic or glass jar

water

food coloring

dish soap

glitter, sequins, or tiny pieces of foil (to act as "debris" or surface objects)

Directions:
First, fill a clear jar with water. Then, add 1-2 drops of dish soap. The dish soap is important since it makes the funnel shape easier to see. After that, add 3-4 drops of food coloring. We used blue food coloring but any color is fine! Now comes the fun part...hold the jar upright and shake it in a rotating, circular motion. Your students will see a mini "tornado" forming. Finish the observation by having students add some glitter, sequins or tiny pieces of foil in the jar. Close the jar, have them shake it again in a rotating, circular motion and watch as the "tornado" lifts the "debris" off the ground!

2. Hurricane in a Bowl
What You Need: Directions:
Start this activity by filling a clear, large bowl 3/4 full of water. Then, use a spoon to stir the water in a circular motion until it is spinning. Spin the water counterclockwise to mimic the rotation of the winds in the Northern Hemisphere or clockwise to mimic the rotation of the winds in the Southern Hemisphere. Finally, quickly add 2-3 drops of food coloring to the center of the bowl. You will see a hurricane shape start to form. Watch as the "hurricane" starts out strong and slowly starts to dissipate as it looses energy over time!

3. Erupting Volcano
What You Need:

baking pan

homemade or store-bought play dough or molding clay

baking soda

vinegar

red food coloring

teaspoon

small measuring cup

Directions:
Begin by building and shaping a volcano on a baking pan using modeling clay or dough. The baking pan is important because it will catch the "lava" to prevent spills and make clean up easier. Next, make an indentation at the top of the volcano to create the opening "vent". Then, put one teaspoon of baking soda into the top of the volcano "vent". In a measuring cup, mix about a ¼ cup of vinegar with 2-3 drops of red food coloring. Slowly pour the vinegar mix into the baking soda and watch the "lava" come oozing out of the vent!

4. Earthquake Shake Table
What You Need:

2 sheets of thick cardboard

2 large rubber bands (elastic)

4 tennis balls (or similar sized balls)

construction materials such as building bricks, play dough, toothpicks, popsicle sticks, wooden blocks

Directions:
This is a really fun STEM challenge for your little engineers! Begin by layering two cardboard pieces on top of each other and place rubber bands around them. Then, slide the tennis balls between the cardboard pieces near each of the four corners. Next, have your students brainstorm model ideas for a secure design. Once they have a design in mind, use the desired construction materials to create a building. Our kids love using building bricks so of course they chose that! Place the building on top of the shake table. Finally, test the earthquake safeness by holding the bottom of the shake table and pulling & releasing one corner on the top. Repeat this step a few times using different amounts of force. You will notice how the building bounces around as you pull and release a few times. Did your building withstand the shaking?
