Segmentation of the Wassuk Range normal fault system, Nevada (USA): Implications for earthquake rupture and Walker Lane dynamics

Abstract Normal faults are commonly segmented along strike, with segments that localize strain and influence propagation of slip during earthquakes. Although the geometry can be constrained by fault mapping, it is challenging to determine seismically relevant a zone. Because histories, geometries, strengths linkages between normal fundamentally control rupture earthquakes, differences in segment rates result differential uplift adjacent footwalls, we used along-strike changes footwall morphology detect relative strength mechanical links them. We applied new geomorphic analysis protocol Wassuk Range fault, Nevada, within actively deforming Walker Lane. The examines characteristics morphology, including range-crest continuity, bedrock-channel long profiles, catchment area variability, relief, strike-parallel characteristics. Results revealed six domains significant identify boundaries. integrated our results previous studies segments, informing seismic hazard assessment. When combined recent geodetic studies, have implications for future evolution Lane, suggesting accommodation across region. Our demonstrates power this method efficiently related behavior, permitting researchers perform reconnaissance assessment segmentation worldwide.
