A 9.0-magnitude earthquake occurred

off the northeastern coast of Japan on 11 March

The earthquake in Japan on March 11,2011 was a 9.0 on the Richter scale (里氏). Over 6,500 died because of the disaster by March 18. The earthquake also caused a tsunami (海啸) and a nuclear leak (核泄漏).

However, most Japanese people stayed calm and orderly.They left broken houses calmly. They waited in line for food, water and public telephones. There was no robbing (抢劫) and no pushing.

Earthquakes hit Japan almost every year. People are ready for an earthquake at any time.

In Japan, you can learn about earthquakes on TV and in schoolbooks. Even the famous comic, Sakura Momoko (《樱桃小丸子》), shows earthquake training in a school. Almost every family in Japan has a survival kit (救生包). The kit has a flashlight (手电筒), a radio, water and enough food for several days.
