earthquake

An earthquake is a vibration or vibration that occurs on the surface of the earth due to the sudden release of energy that creates seismic waves. Earthquakes are usually caused by the movement of the Earth's crust (Earth's plate). The frequency of a region, refers to the type and size of an earthquake that has been experienced over a period of time.

Most earthquakes are caused by the release of energy produced by pressure caused by moving plates. The longer the pressure gets bigger and finally reaches the state where the pressure cannot be retained by the edge of the plate. That's when an earthquake will occur.

the consequences of an earthquake :
