John, I know you have to be careful about passing along someone's unpublished ideas, but this would be interesting-so if you can be more specific, please do. Actually, the other time I entered one of Petra's contests, I chose Bombay Beach, but I was wrong. I'm aware that: it has been maybe 300 years since the last southernmost San Andreas quake; there is a left-lateral fault off of Bombay Beach that lit up a couple of time, including M4+, in the last year or 2; that Elmore Range left lateral M6.2 preceded the Superstition Hills M6.6 by 1/2 day. A couple of Lamont people and I proposed 4 times to NSF to acquire marine seismic reflection data from a barge (constructed from pieces) in Salton Sea, and the left-lateral faults were part of this (as well as an interesting rotation model that Nano did not publish-shown at AGU in, I think, 1998). After 4 rejections, we gave up....
