Brent felt it before I did. "Is that an earthquake?" he asked. And right then the building started to shake a bit. I grabbed the dog and headed to the closest doorway; Brent ran over to our bookshelf and held on to his antique stained-glass window.
The few quakes we've felt since moving up here have been real brief, but this one seemed to linger...a long, low rumble.
Update: It was a 5.6 quake centered near San Jose, about 45 minutes south of San Francisco.
Update 2: The San Francisco Chronicle reports that, at 5.6 on the Richter scale, this is the strongest quake in the Bay area since the infamous trembler of 1989.
