Reverse faults appear on places where there are ocean-continental and continental-continental convergent boundaries, and they are the total opposite of what the normal faults represent. If the hanging wall rises relative to the footwall, than we have reverse fault. This type of faults occur on places that are undergoing a compression/squishing.
