An earthquake is a trembling or shaking of the ground caused by the sudden release of energy that is being stored in the rocks beneath the surface. Once the strain becomes too great, the Earth shifts releasing massive amounts of energy that may vary. How strong an earthquake is, is dependant upon many factors, one being the rock strata in which it occurs.

The accumulated energy at the tectonic plate boundaries are released suddenly. That causes the earth to vibrate is called earthquakes. It releases the dangerous seismic waves and some time it generate Tsunami also.Visit my slide show on earthquakes and Tsunami.

An earthquake is simply what is produced when the Earth's tectonic plates slip. An earthquake produces various seismic waves (P-waves, S-waves, and Seismic waves notably).

An Earthquake is when the plates of the earth shift and overlap. I takes allot of force to pull off this so the plates and ground shift. This causes allot of vibration.
