Earthquakes

An earthquake is one of the worst natural disasters on our earth. We think that the ground we stand on is very stable, but it isn’t. It moves quite a lot. In the last few decades scientists have been able to find out why earthquakes happen.

Earthquakes happen when there is a sudden vibration in the earth’s crust. It’s like a large lorry that travels down your street. When it passes by, you feel your house shake.
