BERKELEY, Calif. (KTLA) -- A 3.9-magnitude earthquake struck near Berkeley Thursday evening, the second quake of the day in the area.
The temblor hit around 8:16 p.m. one mile from Berkeley, according to the U.S. Geological Survey.
The epicenter was three miles from Albany and Emeryville and 11 miles from San Francisco City Hall, the USGS said.
The quake followed close on the heels of another 3.9-magnitude temblor, which hit just after 2:30 p.m. Thursday.
That earthquake was centered about two miles east of Berkeley.
People from Vallejo to Fremont, and part of San Francisco, reported feeling light shaking.
There were no reports of any injuries or major damage from either quake.
Some 8.2 million people were expected to participate in the 2011 Great California Shakeout earthquake drill Thursday, Oct. 20, in preparation for "The Big One."
Participants were urged to drop, cover and hold on during the drill, which began at 10:20 a.m.
