What Are Three Types of Faults?

In a normal fault, the hanging wall, or upper side, of the fault drops down. The forces involved move the sides apart.

In a reverse fault, the opposite happens, and the hanging wall moves in an upward direction. The forces push the sides together.

In strike-slip faults, the walls move from side to side instead of in an up or down direction. No hanging wall exists in this type of fault.
