A natural disaster is a disaster caused by nature, such as floods, volcanic eruptions, earthquakes, tsunamis, avalanches, lahars (volcanic mudslides), landslides, sinkholes, blizzards, drought, hailstorms, heat waves, hurricanes, tropical storms, typhoons, Ice Ages, tornadoes, and wildfires. Epidemics caused by bacteria or viruses are sometimes considered natural disasters, but sometimes put into a different category. A biological threat such as locusts or toxic fungi could also be considered a natural disaster.
The thing about natural disasters is that they can strike at any time in almost any place, even without warning. Throughout history, natural disasters had claimed millions or lives and destroyed countless properties. Their economic cost is rising relentlessly. This is because a growing share of the world’s population and economic activity is being concentrated in disaster-prone places: on tropical coasts and river deltas, near forests and along earthquake fault lines.
Some of the weather disasters can be predicted such as hurricanes and blizzards. The technology is getting better in predicting tornadoes and severe thunderstorms. By getting the data early people can be warned to take shelter or make the necessary preparations.
There isn't any way to avoid natural disasters, but if people know what kinds of disasters are most likely where they live, they can learn what to do if a disaster happens in order to stay safe.
