Update, 09.26.11, 9:53am: Since this story was published, the USGS downgraded the magnitude of this quake to a 3.2. The headline and article have been amended to reflect that.
A 3.2 earthquake with its epicenter 3 miles north-north-east of San Leandro was felt by many in Berkeley at 8:08pm Sunday night. It was a trembler rather than a jolter, with tremors that lasted several seconds.
USGS reported that the quake had a depth of 5.6 miles and that its exact location was 37.755°N, 122.140°W.
Twitter users were, as usual, swift to comment on the event. At 8:08pm, almost as soon as the quake hit, c_mess tweeted: “Berkeley earthquake…a little shudder.” At 8:13, kenztron tweeted: “First Berkeley rain and earthquake all in one day. Byebye SoCal!” Terranisaur posted that it was her first Berkeley earthquake at 8:14pm. And, at 8:23pm, responding to Berkelyside’s tweet about the trembler, SSSTruth tweeted: “O that explains the shaking. I thought it was people jumping for joy because the #raiders won!”
Smaller earthquakes like this one are always a good reminder to get prepared for the eventuality of a big one. Check what you should do on the USGS website.
