Seismic waves, however, move through the ground.Most earthquakes are caused by the movement of large sections of the Earthâs crust, called plates.The place where two plates meet is called a fault. Faults look like large cracks in the ground.hese waves are called seismic waves. These waves are similar to ocean waves, which move through water.
