It would make sense that they come in clusters though. An earthquake happens when tectonic plates slip past each other. When a plate shifts it could create or release pressure somewhere else on the plate. I think this would be a regional phenomenon, so I doubt it would affect a someplace as far away as California. That doesn't mean that an earthquake won't shake CA to little bits of rubble tomorrow, but I think that quake would be unrelated.
