15 Facts about Natural Disasters

Natural disasters are a tragic, yet inevitable part of life that can often cause catastrophic destruction and disruption.  The sheer variety of events defined as natural disasters is mind-boggling. Another intriguing aspect of natural disasters is their unpredictability. Predicting natural disasters is not an exact science as Mother Nature keep her secrets well hidden.

Communities, economies and the environment are usually wrecked by floods, hurricanes, earthquakes etc. It is imperative that we understand the spectrum of disasters to mitigate loss and displacement. This is why many reputable institutions are dedicated to prediction and early warning system research. These disasters can happen anywhere and anytime and preparedness is all the more important for when ‘disaster strikes. This article explores some of the 15 most fascinating, surprising and at times not so fun facts about natural disasters.

1. 鈥淧otato, Potatoh鈥�- Hurricanes, Typhoons and Cyclones, the Difference is the Same!

Image by from

Born of similar weather phenomena Hurricanes, typhoons and cyclones are one and the same. These storms are among the deadliest natural disaster.  In the Atlantic and Northeast Pacific, the term is “hurricane” in the Northwest Pacific it is “typhoon鈥� and in the South Pacific and the Indian Ocean it is 鈥渃yclone”. Despite these regional differences in terminology, these storms are all essentially the same, and their formation depends on similar meteorological conditions.

They form over warm ocean waters and are characterized by a rotating system of thunderstorms.  When a tropical storm reaches sustained winds of at least 74 miles per hour, it is upgraded to a hurricane. These storms can cause significant damage to infrastructure and communities. The resultant storm surges, inundate coastal areas and in the worst-case scenario cause significant loss of life.

2. Natural Disasters are Unpredictable!

Nature’s wrath knows no schedule; disasters strike unexpectedly, leaving chaos and destruction in their wake. Another intriguing aspect of natural disasters is their unpredictability. Loss of life and massive destruction follow these catastrophic events like hurricanes and earthquakes, wildfires and tsunamis.  Accurate prediction of when Mother Nature would wake up is hard. However, with scientific data and technological advancement, we can strive to understand the phenomenon better. While we can monitor weather patterns and seismic activity, the forces of nature are too complex and too unpredictable to be fully understood. Their sudden visitation often without warning leaves communities and individuals just enough time to save only themselves.  We always take steps to mitigate their impact and be forever vigilant.

3. Sometimes Natural Disasters Trigger Each Other

Some natural disasters can trigger other disasters, leading to a cascade of destructive events. For example, landslides and tsunamis most often follow earthquakes. The world鈥檚 deadliest tsunami was the Indian Ocean tsunami of 2004. According to the U.S. Geological Survey, the energy released was equal to 23,000 Hiroshima-type atomic bombs.  As the ground becomes saturated with rain water from hurricanes landslides and mudslides can occur. Wildfires lead to the loss of vegetation which in turn means rainwater rushes downhill unimpeded and causes flash floods.

The smoke from wildfires is also harmful to human respiratory health. Volcanic ash from a volcanic eruption can also cause respiratory problems, aviation accidents and damage to crops and livestock. Overall, the interconnectedness of natural disasters means that the impact of a single event can be massively multiplied. Landslides often accompany earthquakes, floods, storm surges, hurricanes, wildfires or volcanic activity. They are often more damaging and deadly than the triggering event.

Wildfires are natural disasters that also occur without warning. While wildfires can start in a variety of ways, including human activity, lightning strikes, and accidents, they can also occur naturally. One common way wildfires start naturally is through lightning strikes. Lightning is an electrical discharge that occurs in the atmosphere, and it can ignite fires when it strikes a dry patch of land or vegetation. Over 100,000 wildfires burn across the US annually due to lightning striking dry or dead wood or plants. Another way wildfires can start naturally is through spontaneous combustion. 

In a situation of low humidity heat might builds up in a pile of organic material, such as leaves or hay, causing it to ignite.  In addition to lightning strikes and spontaneous combustion, wildfires can also start naturally due to volcanic activity. When a volcano eruptions usually release hot ash and lava, which ignites vegetation and other materials in the surrounding area. Finally, wildfires can also start naturally due to strong winds which can create sparks to ignite dry vegetation and other materials, leading to the start of a wildfire.

5. There Exits a Ring of Volcanoes

The ‘Ring of Fire’ in the Pacific Ocean is where 90 % of all active volcanoes on earth are found.  The most active volcanoes and seismic events on earth are to be found in the horse-shoe-shaped region in the Pacific Ocean.  The Ring of Fire stretches from New Zealand through Japan and along North America’s western coast before turning southward into South America. The most violent of them all Krakatoa, Mount Vesuvius and Mt. St. Helens are domiciled in the ring.

Here, the Pacific Plate grinds against other plates (including the Eurasian Plate and Nazca Plate) causing earthquakes and volcanic eruptions. In addition, major hot spots such as Hawaii, Iceland, Tonga, Samoa, and New Zealand are located along the perimeter of this seismically charged zone.  Frequent volcanic eruptions here often result in vast amounts of ash and lava being released into the atmosphere.

6. Natural Disasters are an Existential Threat

The production, transportation and distribution of food are disrupted by natural disasters, impacting food security. These occasions can incorporate storms, floods, dry spells, fierce blazes, quakes, and other extreme climate occasions. Crops can be destroyed, infrastructure can be damaged. Water supplies are contaminated when a natural disaster strikes. This can result in food shortages and price increases. Likewise, disturbances to transportation and circulation frameworks can make it challenging to get food to individuals who need it, prompting further food weakness.  When people are displaced from their homes by natural disasters they lose access to food and income. This can prompt expanded weakness to ailing health and craving. Building resilience and preparedness measures as well as early warning systems for these events may be long-term solutions.

Climate change has made natural disasters, like heatwaves and wildfires become more frequent and severe. Imagine being forced out of your home and your livelihood by a devastating flood. Being unable to eat because of a drought or a failed harvest. “Climate refugees鈥� are people displaced due to natural disasters. The phenomenon of climate refugees has become more visible in recent years. At least 1.2 billion will be displaced people by 2050, in climate-related events, according to the Australian think tank IEP. Away from their homes, climate refugees face a variety of difficulties. They frequently lack access to basic needs and they may also be subjected to violence and discrimination from their host communities.

8. Up to the Neck in Floods

Floods are the most widespread natural disaster aside from wildfires. According to the 90% of all US natural disasters declared by the president involve some sort of flooding. It’s worth noting that presidential disaster declarations involving flooding vary from year to year, depending on the severity. Hurricanes, tornadoes, wildfires, earthquakes and more are in the list  of disasters that can lead to a presidential disaster declaration.

9.In the US Tornadoes have Touched down in All States

Among formidable weather phenomena on the planet are Tornadoes. The intensity of their winds is what makes them so dangerous. The 300 miles per hour winds cause significant destruction and loss of life. Another factor that makes tornadoes so frightening is their unpredictable nature. They can change course and intensity very quickly, making it difficult for meteorologists to predict their path accurately. This also means that people often have little warning before a tornado strikes, which can be incredibly dangerous. Damage paths of tornadoes can be in excess of one mile wide and 50 miles long. Tornadoes have touched down in all 50 states. However, most tornadoes strike in Florida and the infamous 鈥淭ornado Alley,鈥� an area of the southern plains in the central U.S.

Early warning systems are designed to detect and forecast natural disasters. people who live in the affected areas appreciate these systems. EWS enable people to take precautions to protect themselves and their belongings. Weather stations, seismic sensors, satellite imagery and computer models form the basis of EWS. Mobile phones, radio, television and sirens are employed in sending alerts by the relevant authorities.  By giving early advance notice of catastrophic events, these frameworks can save lives, lessen the effect on foundation and property, and assist networks with recuperating all the more rapidly.  Early Warning System is a critical component of any Disaster preparedness.

11. Natural Disasters Bring Humanity Together

People are usually brought together by natural disasters in ways that are truly remarkable. In such instances, differences are set aside and people tend to work together to help. Foodstuff, clothing and other essential supplies, as well as financial support, are the most common forms of contribution. It may also involve volunteering time and expertise to help with cleanup and recovery efforts.  International aid and cooperation can be crucial in responding to large-scale natural disasters that affect multiple countries or regions. More often than not long running divisions may be set aside as people to work towards rebuilding affected communities. Despite being devastating natural disasters can also bring out the best in humanity.

20 Severe sandstorms take place across desert regions with high winds blowing millions of tons of dust particles miles away reducing visibility and forcing people indoors until it subsides. In this event, strong winds lift large amounts of sand and dust from the ground. The created clouds travel over long distances. Strong winds, low humidity and dry soil conditions combine to whip up sandstorms.  They can damage crops, infrastructure and cause respiratory problems. Sandstorms hasten erosion and desertification.  Sahara Desert in North Africa, the Gobi Desert in Asia and the Arabian Desert in the Middle East are where the cauldron for the biggest dust storms.  However, even coastal areas can experience sandstorms.

13.  Most Avalanches are Triggered by People

Image by from

Sad fact; avalanches are caused by human activity. One reason is that people tend to recreate in areas where there is a high risk of avalanches. Ski resorts, backcountry skiing areas, and mountain climbing routes are all examples of places where people enjoy outdoor activities but are also at a higher risk of avalanches. Another reason is that people can unintentionally trigger avalanches by their movements.  Lastly, people can also cause avalanches by not taking proper precautions.

For example, not checking avalanche forecasts, not carrying the necessary safety equipment, or not following safe travel protocols can all increase the risk of triggering an avalanche.  According to National Geographic, in 90% of avalanche fatalities, the avalanche is started by the victim or someone in the victim鈥檚 party. Avalanches can reach speeds of 80 miles per hour. Education on the proper safety measures can help to minimize the risk of triggering an avalanche.

14.  Did you Know Lakes also Erupt?

A “limnic eruption,鈥� is also known as a “lake overturn.” In this event, a large amount of carbon dioxide (CO2) is suddenly released from the bottom of a water body. This can happen when a lake is saturated with CO2. The trigger can be an earthquake or landslide, which causes a disturbance. On reaching the surface the CO2 rapidly expands and displaces the air. The deadly cloud of CO2 spread across the surrounding area suffocating unknowing people.

Limnic eruptions are rare but can be extremely dangerous. The most famous limnic eruption occurred in Cameroon in 1986 when a cloud of CO2 erupted from Lake Nyos and killed more than 1,700 people and thousands of livestock. The odourless and colourless gas is heavier than air and floated across the ground to the village where it asphyxiated the residents while they slept.

While some disasters may be localized, others can be felt worldwide, affecting people and ecosystems far beyond the disaster’s epicentre. One such disaster that can be felt globally is a volcanic eruption. Volcanic eruptions release ash which can travel great distances. It affects the climate and air quality.  Mount Pinatubo eruption in the Philippines in 1991, resulted in a cooling of global temperatures and affected air travel for months. Another disaster that can have global repercussions is an earthquake. Powerful earthquake occurs, cause tsunamis.  The largest earthquake ever recorded anywhere in the world occurred in 1960 in Chile. It was a whopping 9.5 on the Moment Magnitude scale. The resulting Tsunami caused damage over 9,000 miles away on the California coast.

Natural disasters are a force of nature that we cannot control, but we can prepare ourselves for.  We can take steps to mitigate their impact on our lives and communities by understanding the facts about natural disasters. Being prepared can make all the difference. Stay safe, stay informed, and be ready for whatever nature throws our way. From the power of hurricanes to the unpredictability of earthquakes, these facts provide an interesting insight into the world of natural disasters.
