Scripps graduate students Drake Singleton (foreground) and Susheel Adusumilli were among Scripps researchers who traveled to Ridgecrest, Calif. July 13 to examine the surface rupture of the 7.1-magnitude July 5 earthquake there and related effects. Photo by Nick Lau.
The group set up GPS stations around Ridgecrest to monitor crustal motion as a result of the earthquake. This location was at the southern terminus of the surface rupture. The students were looking at one of the conjugate (semi-perpendicular) faults that developed as the rupture came to a stop at its southern end. Aftershocks including a 4.7-magnitude quake on July 25 have continued to strike since the original event.
