Scientific paper

A left-lateral strike-slip fault perpendicular to the major transform fault that occurred at the extended continental crust in the middle of the Gulf of California, produced a remarkably active main shock and aftershock seismic sequence that began on 1 September 2007. In contrast to observations from oceanic transform fault systems this event induced unusually active seismicity. By means of an inversion procedure, we obtained the moment tensor solutions of all the events greater than Mw 4.4, and we observed multiple types of faulting: some very similar to the main event, and others that included a tensional cracking mechanism with a significant nondouble couple component. Static stress change for optimally oriented left-lateral faults predicts the seismic activity. This event has implications for the Californian peninsular geology, especially for the late Miocene fault systems that were optimally reoriented to promote active faulting.
