A small earthquake shook part of the South and East Bays this morning at 10:32 a.m., and the USGS is saying it had a magnitude of 3.3 and was centered just north of Alum Rock, apparently along the Hayward Fault.

A similarly small quake on the Hayward Fault happened in Berkeley back in June.

Did you feel it? KTVU's Maureen Naylor did, and she posted a video of a window shade cord swaying, so, yeah, pretty small.

Others reported it lasted about three to four seconds.

Let this serve as yet another helpful reminder to get an earthquake kit together! Our pals at LAist just put together a fast and dirty guide to building one using Amazon Prime alone.

But people really need to stop posting stuff like this for a 3.3M.
