Other Disasters


There are several types of disasters, such as tornadoes, earthquakes, tsunamis, etc. Tsunamis are huge tidal waves caused by undersea earthquakes. Their height can go up to 100 ft or more. The speed of a tsunami can go as fast a jet airplane. Tsunamis can appear as a foot high, but as they reach the shoreline and approach shallow water, they slow down and start gaining more energy and height. Tsunamis may also be caused by landslides or volcanic eruptions.

 

 

Earthquakes occur when plates or rocks within the earth break or shift causing shock waves. Thousands of earthquakes happen every day, but most of them are very light to be noticed. On average, severe earthquakes that cause massive damage happen once every five years. Earthquakes can destroy cities, cause volcanic eruptions, break dams, and can create landslides. The most dangerous earthquake that ever happened was in China in 1557. It is estimated that 817,000 people had died.

 

Tornadoes happen when there is a column of rotating air that extends from a thunderstorm to the ground. It's often anticipated as a dark, greenish sky and black storms gather. Baseball size hail might fall. And a funnel appears, descending from a cloud. A tornado can tear up anything in its path.
