A fault is a fracture or zone of fractures between two blocks of rock. Faults allow the blocks to move relative to each other. This movement may occur rapidly, in the form of an earthquake - or may occur slowly, in the form of creep. Faults may range in length from a few millimeters to thousands of kilometers.

What Is a Fault Line? The San Andreas Fault line cuts through a valley at the foot of the Coast Range Mountains in San Benito County in the U.S. state of California.
