The orientations of brittle structures predicted compare favorably with those found in natural large-scale dilational jogs, such as the Vienna basin, the Dead Sea basin, and the Brawley jog (California), as well as in mesoscopic...

... and deactivated the late Cenozoic West Salton detachment fault. Sandstone and mudstone of the Brawley Formation accumulated between ∼1.1 and ∼0.6–0.5 Ma in a delta on the margin of an arid Pleistocene lake, which received sediment from alluvial fans of the Ocotillo Formation to the west-southwest. Our analysis...

... in the last 30 years, the Southern California Seismic Network has recorded a M ≥ 3.0 earthquake in this part of the Salton Sea. However, those events showed focal mechanisms more consistent with the Brawley Seismic Zone. This is a region of seismicity that extends up the Imperial Valley from the Imperial...

Could this moderate event have triggered, or otherwise been causally associated with, the surface slip on the San Andreas fault? The event was large enough to be associated with surface slip...
