     When some plates of the earth move suddenly, an earthquake happens. Many earthquakes begin under the

sea. Earthquakes may happen anywhere on the earth. They often happen near the mountains.

     During an earthquake, the shakings make rocks rise suddenly and even crack (断裂) open. Houses fall,

people are killed or hurt, and sometimes the whole villages or cities are destroyed.

     Can we do something to keep ourselves safe from earthquakes? Scientists have studied earthquakes and

make maps that show the "earthquake belts". In areas (地区) in these belts, it's possible for earthquakes to

happen. In these areas we should build strong houses to fight against earthquakes.

     In the future, scientists will be able to tell when and where an earthquake will be before they happen. They

can also tell people what to do and how to do it.
