On Sunday morning, a strong earthquake hit Indonesia and then big tsunamis(海啸)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. One third of them were children, and most of them were 5 to 12 years old.
In may Asian countries near the sea, poor kids helped their parents fish. So they were in harm's way
when the tsunamis came. In Sri Lanka, when the first waves hit, thousands of children came to the
seaside. The waves brought in fish. The old and the young collected them. Many waited for more.
Then tsunamis six metres high hit the island of 19 million people.
''They got caught and could not run to safety. This is the reason why so many children have died,"
said a police spokesman in Sri Lanka.
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 on day, they may affect 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. Islands around
China also help the country avoid them.
What should you do when there's a tsunami? Move to a safe place. If you are near the sea and you
feel the earthquake, move to higher ground. Stay away from rivers and streams.
