Earthquakes are caused by an abrupt shift of rock along a fracture in the Earth.
Most earthquakes are caused by slow movements inside the Earth that push against the Earth's brittle, relatively thin outer layer, causing the rocks to break suddenly.
Earthquakes occur when the rock underneath the surface of the Earth break or shift. This causes the surface to shake, sometimes very violently. You can find more information here: http://www.geo.mtu.edu/UPSeis/why.html
