Update 8:20 p.m. Another quake, this one a 3.8, epicenter right on the UC Berkeley campus. Check out the map from the USGS and zoom in all the way to see the location. It appears to be a house right off of Piedmont Avenue. (Update 9:06 p.m. Berkeleyside says it's the International House.)
Here are all of the responses coming in on the USGS "Did you feel it" page.
No tsunami alert, by the way.
From a California Beat tweet:
EARTHQUAKE UPDATE: Very minor damage reported from businesses in Berkeley, North Oakland & Montclair areas; no injuries after 3.9 quake.

Video report on the first quake from KGO:
And from KQED's QUEST, in 2008: The Hayward Fault: Predictable Peril
Boy someone went to a lot of trouble to make today's Great Shakeout earthquake drill really realistic.
Oh wait. That was a real quake. Two miles ESE of Berkeley says the USGS. Originally reported as 4.2, now downgraded to
3.9. (Update 4:39 p.m. Now upgraded to a 4.0) It got pretty jiggly here in our San Francisco office.
The USGS map shows the epicenter as right on the Clark Kerr Campus in Berkeley, along the Hayward Fault.
Here is the USGS's "Did you feel it" page, which shows as of right now over 12,000 responses from 250 different zip codes, covering a wide swath of the Bay Area and beyond.
Yes there was a drill earlier today but now trains on 15-minute delay systemwide to do routine safety checks after that actual quake.

And from MUNI 27 minutes ago:
Subway being operated manually by procedure after earthquake, expect minor delays for the next 30 minutes
