An earthquake is caused by a sudden slip on a fault. When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earths crust and cause the shaking that we feel. In California there are two plates - the Pacific Plate and the North American Plate.
What are the causes of earthquake explain?
Earthquakes are the result of sudden movement along faults within the Earth. The movement releases stored-up elastic strain energy in the form of seismic waves, which propagate through the Earth and cause the ground surface to shake.
What causes an earthquake facts and information?
Natural events such as volcanic eruptions and meteor impacts can cause earthquakes, but the majority of naturally-occurring earthquakes are triggered by movement of the earths plates. The earths surface consists of 20 constantly moving plates. The pressure increase from shifting plates can cause the crust to break.
What are 10 facts about earthquakes?
Top 10 Facts About Earthquakes!Earthquakes usually happen on the edge of tectonic plates. Earthquakes occur when the plates get stuck but keep trying to move! Before an earthquake foreshocks might occur. After an earthquake aftershocks are likely to happen.
