Abstract

The northern Walker Lane (NWL) comprises a complex network of active faults in northwestern Nevada and northeastern California. It is bounded on the west by the Sierra Nevada and on the east by the extensional Basin and Range Province. Because deformation is distributed across sets of discontinuous faults, it is particularly challenging to integrate geologic and geodetic data in the NWL to assess the region's seismic hazard. Recent Global Positioning System (GPS) measurements show that roughly 1 centimeter per year of relative displacement is accumulating across a relatively narrow zone, but it is not clear where or how much of this strain might ultimately be released in damaging earthquakes.
