One happened this morning and should of made minor circles around the news. A more powerful one (not anything enough to nock over a glass or do anything but shake the foundation a bit) hit only a couple minutes ago. Even in Earthquake prone California, two Earthquakes of at least 4.0-4.5 each isn't a normal occurance. I am only a bit worried because our little state is do for a MASSIVE Earthquake sometime between now and 2030, so this may be an "early preview" of the big one comming early, so I would suggest that you make sure your Earthquake insurance is inline, and that you stay away from San Fransisco, since that place will be demolished if anything over a 8.0 hits (mostly do to the fact that half the city is built on little more than sand along the shore.
