Active Deformation of the Walker Lane Belt

The Walker Lane Belt, which trends from eastern California to Western Nevada is a seismic belt accommodating strain from the movement of the Pacific plate relative to the North American plate.  Striking roughly N35W, it along with the ECSZ(East California Seismic Zone) and the CNSZ(Central Nevada Seismic Zone) are thought to accommodate about 25% of the relative plate motion between the North American & Pacific plates, with most being accommodated by active faults in the Walker Lane region.   It accommodates mostly right lateral shear although some left lateral shear can be found trending to the NE, as well as some basin and range style extension almost perpendicular to the main axis of it's trend.
