It is a flat surface that may be vertical or sloping.
Thrust faults with a very low angle of dip and a very large total displacement are called overthrusts or detachments.
The hanging wall block would then be hanging overhead.
This fault pattern arises because the hanging wall growth faults nucleate in the sediment volume above the point at which the detachment surface flattens out causing an apparent migration of the active growth faults towards the bounding fault as the hanging wall block is displaced away from the footwall listric fault mechanism.
Two types of vertical faults are recognized.
Thrust faults are reverse faults that dip less than 45.
In our models a rigid block and horizontal base act as the footwall of the master normal fault and a layer of wet homogeneous clay represents the hanging wall strata.

The fault strike is the direction of the line of intersection between the fault plane and earth s surface.
Where the fault plane is sloping as with normal and reverse faults.
The foot wall block is the block which would be under the feet of a person standing in a tunnel on the fault plane.
A reverse fault is the opposite of a normal fault the hanging wall moves up relative to the footwall.
The upthrown side of the fault is the side on which the movement has been up relative to the other side.
The fault plane is where the action is.
The dip of a reverse fault is relatively steep greater than 45.
