There are geological reasons (stiffness of dirt I think) that a big one near the California coast isn't likely to be that significant. The next earthquake will probably be another Loma Prieta. The ground just isn't very likely to transmit the energy far from the epicenter. Also it's the Hayward fault that's likely to go next.
