A

When some plates of the earth move suddenly, an earthquake happens. Many earthquakes begin under the sea. In fact, earthquakes may happen anywhere on the earth. They often happen near 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 made maps that show“earthquake belts（带）”. In these belts, it’s possible for earthquakes to happen. In these areas we can build strong houses to fight against earthquakes.

In the future, scientists will be able to predict exactly（精确预报）when and where an earthquake will happen. They can also tell people what to do and how to do it.
