On Sunday morning, a strong earthquake hit Indonesia and then big tsunamis(海嘯) followed. They soon went on to other countries in the south and southeast Asia as well as East Africa.
Tsunamis are especially dangerous for children. By Wednesday,  nearly 60 000 people died because of the tsunamis. 30% of them were children,  and most of them were 5 to 12 years old.
In open seas tsunamis are only one or two metres high. When they are near land, they are as high as 10 metres,  Houses and cars near the sea can be taken away by these big waves. Because tsunamis move fast and can travel to another side of the sea within one day, they may affect(影響)a lot of places.
The Pacific Ocean(太平洋)has a lot of strong tsunamis because of the size of the ocean and large earthquakes there. China doesn\'t see tsunamis often because its sea floor is quite flat(平的). Islands around China also help the country avoid from them.
What should you do when there\'s a tsunamis? Move to a safe place. If you are near the sea and you feel the earth shake, move to higher ground. Stay away from rivers and streams(溪流).
