Scientists from USGS & CGS and Navy escort, and a UCLA engineer from the GEER team, inspect ~12 +/- 3 foot high fault scarp with from 3 to 5 feet of right-lateral motion near the expected maximum slip locality along the primary tectonic rupture associated with the M 7.1 event.

Team discussion among CGS and USGS earthquake scientists at the location of the primary surface fault rupture where is has disrupted and offset an access road at the NAWS China Lake. The fault runs NW to SE across the road, which runs from west to east. The east side of the road is uplifted relative to the west side.

USGS scientists and partners review objectives and group assignments at fault scarp site. The team will deploy seismic instruments to better observe aftershock activity from close in, and to document surface faulting.
