Another quake was felt in Berkeley tonight. The early estimate from USGS was that the 8:16 p.m. quake with an epicenter at the International House on the Cal campus had a magnitude of 3.9.
For the several thousand (including Berkeleyside) in the Greek Theater, the quake struck just a couple of minutes before Paul Simon took the stage. The crowd cheered the quake.
