difference between right and left lateral strike slip
Fault (geology) In a strike-slip fault (also known as a wrench fault, tear fault or transcurrent fault),[7] the fault surface (plane) is usually near vertical and the footwall moves laterally either left or right with very little vertical motion. Strike-slip faults with left-lateral motion are also known as sinistral faults. Those with right-lateral motion are also known as dextral faults.[8] Each is defined by the direction of movement of the ground as would be seen by an observer on the opposite side of the fault.
