TSUNAMI
Definition
A tsunami is a series of fast moving waves in the ocean caused by powerful earthquakes or volcanic eruptions.
Causes and What we can do?
The waves travel at a great speed across an ocean with little energy loss. They can remove sand from beaches, destroy trees, toss and drag vehicles, damage houses and even destroy whole towns. Tsunamis can also be caused by meteorite impacts.
Tsunamis cannot be prevented. However, there are ways to help stop people dying from a tsunami. International and regional warning systems, especially for the Pacific Ocean, issue alerts before the big waves reach the shore. When an earthquake that caused the tsunami can be felt before the wave gets to the shore, people can be warned to go somewhere safe.
