摘要：

We employ seismic reflection, magnetics, and electromagnetics to locate precisely the southern extension of the Pahrump Valley Fault Zone (PVFZ) and examine its subsurface geometry. The southern extension of the PVFZ is active and represents a potential seismic hazard for Las Vegas. We observe pronounced magnetic and conductivity anomalies, and truncations of reflectors in the seismic profiles coincident with one of three Holocene scarps in southern Pahrump Valley. These geophysical techniques in combination can locate faults more precisely than the presence of eroded scarps.
