Answer:
earthquakes are caused by faulting, a sudden lateral or vertical movement of rock along a rupture (break) surface. ... An earthquake is the shaking that radiates out from the breaking rock. People have known about earthquakes for thousands of years, of course, but they didn't know what caused them.
