Don't you live in California?
I do... But we haven't had anything over a 6.0 in a long while... Honestly I don't think there are very many places which are 'Rock Solid' in that they don't have any seismic activity. I recently read that even NY may have a big earthquake some day...

Earthquakes May Endanger New York More Than Thought, Says Study
Indian Point Nuclear Power Plant Seen As Particular Risk
A study by a group of prominent seismologists suggests that a pattern of subtle but active faults makes the risk of earthquakes to the New York City area substantially greater than formerly believed. Among other things, they say that the controversial Indian Point nuclear power plants, 24 miles north of the city, sit astride the previously unidentified intersection of two active seismic zones. The paper appears in the current issue of the Bulletin of the Seismological Society of America.
Many faults and a few mostly modest quakes have long been known around New York City, but the research casts them in a new light. The scientists say the insight comes from sophisticated analysis of past quakes, plus 34 years of new data on tremors, most of them perceptible only by modern seismic instruments. The evidence charts unseen but potentially powerful structures whose layout and dynamics are only now coming clearer, say the scientists. All are based at Columbia University’s Lamont-Doherty Earth Observatory, which runs the network of seismometers that monitors most of the northeastern United States.

California has mini-earthquakes every day:
