Well, that was interesting. A reasonably-sized earthquake just shook the Bay Area. The initial reports have the magnitude at 5.6 (moderate) and the epicenter being northeast of San Jose, but I certainly felt it here at my office in the hills above San Mateo. It felt like a sort of rolling sensation for up to ten seconds or so. Areas built on fill land reported longer rocking and rolling. News reports have things having come off shelves in San Jose-area grocery stores. The epicenter is closer to my house than it is to my office, so I'll be interested in seeing if anything went wrong at home.
