That can indeed happen. Landers triggered Big Bear. And they say that when a fault goes on one side of the SF Bay, a response quake happens within two years, usually, on the other.

Sorry if I sound kind of fuzzy-brained; I had to have some facial surgery today and I am riding high on Percocet. Bed soon, I imagine.
