When some plates of the earth move suddenly, an earthquake（地震） happens. Many earthquakes begin under the sea. In fact, earthquake s may happen anywhere on the earth and they often happen near high mountains. During an earthquake, houses fall and people are killed or hurt, and sometimes the whole villages or cities are destroyed（被毁灭）. Can we do something to keep ourselves safe from earthquakes？Scientists have studied earthquakes and made maps that show the "earthquake belts". It' s possible for earthquake s to happen in many places of these belts. In these places we should build strong houses to flight against earthquakes.
In the future, scientists will be able to predict（预测） exactly when and where an earthquake will happen. They can also tell people what to do and how to do it.
