Question

A fault in which the hanging wall moves down relative to the footwall is a ______.

Answer 1

Answer:

Option (B)

Explanation:

The fault usually refers to the planar type of fractures that occurs in the earth's crust. Those faults in which the hanging-wall (H.W) block goes down with respect to the foot-wall (F.W) block is considered as the normal fault. This type of fault occurs due to the tensional force or extensional force.

Here, the rocks move in the opposite direction. This movement of blocks results in the release of a certain amount of energy that leads to the occurrence of shallow-focus earthquakes.  

Thus, the correct answer is option (B).
