The figure shows a normal fault, which forms from horizontal tension stress. This stress pulls the rock apart, causing the hanging wall to drop down relative to the footwall. Confining pressure and horizontal compression would not create this type of fault. Horizontal pushing may create a reverse fault, where the hanging wall moves up relative to the footwall.
