Quizplus · Accepted Answer

In a normal fault, the hanging wall moves downward relative to the footwall due to tensional forces in the Earth's crust. However, in the given scenario, the footwall is moving upward relative to the hanging wall, which indicates that the tensional forces have been overcome by compressive forces, causing the footwall to uplift. Therefore, the fault is a reverse fault, also known as a thrust fault, where the hanging wall is pushed up and over the footwall. Strike-slip faults involve horizontal movement along a fault plane, which is not the case here.
