Question

When the hanging wall moves up relative to the footwall it is a blank fault

Answer 1

Reverse fault would be the answer

Answer 2

Answer: When a hanging-wall moves upward relative to a foot-wall, then we call this type of fault as the reverse fault. Reverse faults are generated because of the compressional forces exerted on both the sides of the fault. It is the region that undergoes compression.

For example, many parts of the Himalaya has undergone reverse faulting.
