A Little Shaking in San Francisco – Didn’t Feel Like a Scary Earthquake Here

Monday, June 28th, 2010

7:47 AM, June 28th – The bay area just got a few little rolls from an “adorable” quake that had an epicenter just three miles to the west of the San Francisco Zoo, under the Pacific on the San Andreas Fault.

The animals at the zoo are unnerved:

“I can hear the Peacocks at the @sfzoo flipping out over the little earthquake.”

Oh well. Here it is, from the USGS:
