Description: The measures below require knowledge of the fault slip direction, as evidenced directly (e.g. by slickensides at outcrop or by offset linear features such as fluvial channels) or indirectly (by stress field analysis or by seismically mappable corrugations on the fault plane).
NS (Net slip): The true displacement of the fault
DS (Dip slip): The component of NS parallel to the dip of the fault plane
SS (Strike slip): The component of NS parallel to the strike of the fault plane
LM: Dip separation
Note: DS ≠ dip separation!
