The short answer is that earthquakes are caused by faulting‚ a sudden lateral or vertical movement of rock along a rupture (break) surface. Here’s the longer answer: The surface of the Earth is in continuous slow motion. This is plate tectonics--the motion of immense rigid plates at the surface of the Earth in response to flow of rock within the Earth. The plates cover the entire surface of the globe. Since they are all moving they rub against each other in some places (like the San Andreas
