In a normal fault, the hanging wall moves downward relative to the footwall, creating extensional forces. In a reverse fault, the hanging wall moves upward relative to the footwall, generating compressional forces.
No, a hanging wall and a footwall are not the same in geology. The hanging wall is the block of rock above a fault line that moves down relative to the footwall, which is the block of rock below the fault line that moves up.
The result is a normal fault, where the hanging wall moves down relative to the footwall due to extensional forces pulling the rock layers apart.
That geological structure is called a normal fault, where the hanging wall moves down relative to the footwall. If the hanging wall slides up and over the footwall, it is known as a reverse fault.
A reverse fault is in a zone of compressional faulting, rocks in the hanging wall are pushed up relative to rocks in the footwall. A normal fault is in a zone of tensional faulting, rocks in the hanging wall drop down relative to those in a footwall forming a normal fault.
In a normal fault, the hanging wall moves downward relative to the footwall, creating extensional forces. In a reverse fault, the hanging wall moves upward relative to the footwall, generating compressional forces.
thrust
This is true of normal faults. In thrust or reverse faults, the hanging wall moves up relative to the footwall and in strike slip faults, it moves horizontally relative to the footwall.
In a normal fault, the hanging wall moves down relative to the foot wall.

Reverse Fault
A normal fault.
A reverse fault is a fault in which the hanging wall moves up relative to the footwall.
In a normal fault, the hanging wall moves down relative to the footwall, whereas in a reverse fault, the hanging wall moves up relative to the footwall.
the hanging wall moves down relative to the footwall
