Which of the following best describes reverse faulting?
(a) A fault caused by horizontal tension where the hanging wall moves downward
(b) A fault resulting from compressional forces where the hanging wall moves upward
(c) A fault formed due to vertical uplift without lateral movement
(d) A fault where both blocks slide past each other horizontally without vertical displacement

Recently, the Kamchatka Peninsula was hit by a powerful 8.8-magnitude earthquake. Scientists believe the quake was caused by shallow reverse faulting.
Reverse faulting occurs when compressional forces in the Earth&rsquo;s crust cause the hanging wall (the block of rock above the fault plane) to move upward relative to the footwall (the block below). This type of movement is commonly observed at convergent plate boundaries, where tectonic plates push against each other.
