A thrust fault is a type of reverse fault where the angle of the fault plane is shallow, causing the hanging wall to move up relative to the footwall. Thrust faults are significant in structural geology for understanding compressional forces that lead to the shortening of the Earth’s crust, often associated with mountain building.
