strike-slip fault

Detailed explanation-1: -If the hanging wall moves down relative to the foot wall, then it is a normal fault. b. If the foot wall moves down relative to the hanging wall, then it is a reverse fault.
Detailed explanation-2: -In normal faults, the hanging wall moves downward relative to the footwall (Figure 13 and Figure 14). This motion can be determined by tracing the offset of the beds in a vertical motion in a block diagram.
Detailed explanation-3: -Normal faults move by a vertical motion where the hanging-wall moves downward relative to the footwall along the dip of the fault. Normal faults are created by tensional forces in the crust.
Detailed explanation-4: -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.
