Faults are zones in the earth's crust where there has been movement, such as the famous San Andreas fault zone in California. A fault occurs when internal forces cause rocks in the earth's crust to rupture and move against one another. These sudden ruptures and grinding move-ments release the energy that causes the ground-shaking, which we call
