Detailed explanation-1: -Faults which move along the direction of the dip plane are dip-slip faults and described as either normal or reverse (thrust), depending on their motion. Faults which move horizontally are known as strike-slip faults and are classified as either right-lateral or left-lateral.
Detailed explanation-2: -Movement of rock along a fault may occur as a continuous creep or as a series of spasmodic jumps of a few metres during a few seconds. Such jumps are separated by intervals during which stress builds up until it overcomes the frictional forces along the fault plane and causes another slip.
Detailed explanation-3: -Faults are classified according to the direction of relative movement along the fault. The terms hanging wall and foot wall refer to the relative position of the plates after movement.
