What is an Earthquake?

An earthquake is when two plates clash together. An earthquake builds up in the hypocentre.

What causes an earthquake is when tectonic plates move around and shake the ground.

There are two different types of waves. They are called P-waves and S-waves. The P-waves stand for primary waves and the S-waves stand for secondary waves.

New Zealand's famous earthquake was the Napier and Hastings earthquake. It was seventy-eight years ago.

Be prepared for an earthquake. It could happen any second.
