Earthquakes are not scattered anywhere but happen in certain areas. They happen in places where pieces of the Earth"s surface meet.

Another way to predict earthquakes is to look for changes in the earth’s surface, like a sudden drop of water level in the ground. Some people say animals can predict earthquakes.
