Detailed explanation-1: -reverse (thrust) fault-a dip-slip fault in which the upper block, above the fault plane, moves up and over the lower block. This type of faulting is common in areas of compression, such as regions where one plate is being subducted under another as in Japan.
Detailed explanation-2: -Reverse or Thrust Faults: The opposite of a normal fault, a reverse fault forms when the rocks on the “uphill” side of an inclined fault plane rise above the rocks on the other side. Reverse faults often form along convergent plate boundaries.
Detailed explanation-3: -The forces that create normal faults are pulling the sides apart, or extensional. Reverse faults form when the hanging wall moves up. The forces creating reverse faults are compressional, pushing the sides together. Transcurrent or Strike-slip faults have walls that move sideways, not up or down.
Detailed explanation-4: -Reverse faults results of compressional forces when rocks are displaced towards each other. Strike-slip or transform faults results from either compressional or extensional forces when rocks slip parallell to each other.
Detailed explanation-5: -There are four types of faulting–normal, reverse, strike-slip, and oblique. A normal fault is one in which the rocks above the fault plane, or hanging wall, move down relative to the rocks below the fault plane, or footwall.
