Final answer:
Free wall rupture usually manifests as the movement of one wall over the other in a fault, with different types of motion depending on the fault type.
Step-by-step explanation:
Free wall rupture usually manifests as the movement of one wall over the other in a fault. In a strike-slip fault with horizontal displacement, the blocks on either side of the fault are called the walls. If the fault has a dip that is not vertical, it is a dip-slip fault, and one wall is over the other. In normal faults, the hanging wall moves down, while in reverse faults, the hanging wall moves upwards. A thrust fault is a special type of reverse fault with a gentle dip that is more common than reverse faults.
