Reverse faults are the opposite of normal faults, they occur when the hanging wall rises relative to the footwall.
Reverse faults take place in areas that are undergoing compression. Reverse faults are caused by compressional stress which causes rocks to push into each other. The hanging wall and the footwall are pushed together, and the hanging wall moves upward along the fault relative to the footwall.
With normal faults, the hanging wall and footwall are pulled apart from each other, and the hanging wall drops down relative to the footwall.
