急求有关海啸知识的英文介绍

Tsunami is a Japanese word that means "sea wave". A tsunami is a huge sea wave that forms mainly in the Pacific Ocean area. People die and property is destroyed when a tsunami hits land. What causes these dangerous sea waves? Sometimes, tsunamis are caused when earthquakes take place underwater. Then, water begins to move up and down from the top of the ocean right down to the bottom. Waves begin to form, and each wave is called a tsunami.

A tsunami is less than one meter high and can move at speeds of almost 800 kilometers per hour while it is far out in the ocean. But the tsunami rises much higher and moves more slowly as it comes closer to land.

The weather bureu warns people over radio and television stations when a tsunami is heading for land. These warnings have helped save many lives.
