The California Geological Survey's (CGS) role:The April 2010 El Mayor-Cucapah earthquake revealed a previously undiscovered fault in the desert of Baja California, Mexico. Although the fault is relatively small, it produced a magnitude 7.2 earthquake. Scientists have become interested in smaller faults, because they are frequently the location of unexpectedly large earthquakes.
