Ojai 4.2

The quake was near Ojai, and like the one near the Malibu Coast fault, was strike-slip. Ojai is best known to me as the family home of the Bionic Woman (the character on TV, not the actress (Lindsey Wagner?). It is also where the surface part of the major active thrust fault, the San Cayetano fault, peters out...but it is likely the fault continues west as a blind fault (examples, Namson and Davis, Huftile, Yeats etc). It trasfers its slip southwest to the Red Mountain fault, which Marc Kamerling and I mapped to just off of the UCSB campus. It is also near the seafloor just offshore Santa Barbara point, and dips north beneath the coast. There is an old petroleum test well at or near Santa Barbara point that goes down about 3 km and probably stops just short of the fault.

If the quake was on the NE-striking nodal plane, it was left-lateral, an orientation and slip that would help transfer the shortening to the Red Mountain fault (as a "tear" fault).

Yeah, I get emails from UCSB about what is going on with the fire.
