Fault plane is called the hanging wall or headwall. Thrust faults are reverse faults that dip less than 45. The block below is called the footwall. The hanging wall moves downward relative to the footwall.

A normal fault occurs when the crust is extended. The fault plane is where the action is. Thrust faults with a very low angle of dip and a very large total displacement are called overthrusts or detachments. Reverse dip slip faults result from horizontal compressional forces caused by a shortening or contraction of earth s crust.
