I was awoken this morning by a shaking apartment, and the associated noise, as a 4.2 earthquake rattled the Bay Area. It hit at 4:42 AM with an epicenter beneath Oakland.
I remained out of bed for about 30 minutes after the quake, reading groggy Twitter messages from others, while waiting for any aftershocks. Strangely, none occurred, as the quake is still listed as the most recent by the USGS.
Both CNN and the San Francisco Chronicle have published articles about the event.
