There was a M3.1 just east of Ojai, southern California. Ojai is where the bionic woman lived on TV. Otherwise, it has no claims to fame. The quake was near the west end of the surface trace of the San Cayetano fault. The San Cayetano fault is one of the most active faults in California-with in one place (Fillmore) a minimum of 9 km slip in the last 1 million years (9+ mm/yr). That actually seems too high-some of this may be gravity driven as the deep Ventura basin sedimentary basin compacts, the fault must rotate into the basin (rotate about a horizontal axis). This earthquake was preceded by smaller quakes. It was trenched a couple of years ago by Dolan, Rockwell, others, and they found that it has slipped several meters at the surface during or after the 1600s. The speculate that it was the historic 1812 earthquake (the second of 2 13 days apart, the first was on the San Andreas fault at Wrightwood). The general system of N-dipping faults include to the east the faults responsible for the M6.6 or so San Fernanco earthquake in 1971. To the west, it includes the Red Mountain fault and then the offshore Pitas Point-North Channel-Red Mountain fault system. We are working on a paper on that offshore system.....it would be a shame if it fired off before we get it written and published....Chris
