A Major or Great strike-slip earthquake on the San Andreas (or other) strike-slip fault triggering one of the major active thrusts that uplift the Los Angeles area mountains (the Sierra Madre for example) is a sort of worst case for southern California. I was at some meeting a decade ago where this scenario came up; maybe a SCEC workshop.

I did a search on the USGS map engine, centered on 11S 165E with all M7+ quakes since 1980 within 1000km radius. There's 41 listed. I think this is one the of the most active quake zones in the world for large quakes.

I'd include a link to the map, but the new USGS map urls conflict with the forum software and don't come out right.
