Don,

I know the probabilities of a 7+ quake in the Bay Area. Sorry your map doesn't include Santa Cruz County. Still waiting for an answer. How do you KNOW the rock beneath the Bay Area on one or more faults has already shifted (as opposed to being locked, and therefore, stationary) and we on the surface are just waiting for the ground beneath our feet to catch up with this shift?

Sorry if that question surprises you, and that Petra found it "pitiful." You two are making me not want to post here anymore. If I can't ask a legitimate question without being ridiculed, I may have to go into lurker mode and glean what I can from answers from more educated individuals than I to lay people's questions. Sorry I surprised you. I thought it was a legitimate question.
