Characterizing the tectonic geomorphology of the SAF fault zone is valuable for numerous reasons. The geometry and motions of the blocks that comprise the upper few km of the fault zone inform studies of rupture dynamics, fluid flow along fault zones, fault zone strength, and evolution of fault zone fabrics (e.g., Scholz,1991). Using landformsas markersof thehorizontal andvertical motions alongand across the fault zone,
