According to the US Geological Survey, a 3.6 magnitude earthquake struck the Bay Area early this morning, shaking folks in San Francisco, down the peninsula, and as far north as Vacaville.

The quake struck at 12:06 a.m. Thursday, and had an epicenter about 1 mile northwest of San Ramon, with a depth of 6 miles.

3080 Bay Area residents stopped whatever it was they were doing at that hour long enough to let the USGS know they felt the quake, including 33 folks in San Francisco who reported they had been shaken.

The majority of the respondents were based in the East Bay, with thousands reporting feeling the "weak" to "light" quake.

“All of a sudden I know this sounds a little weird, I felt a little dizzy,” San Ramos resident Ross Butler told CBS5.

“And then all of a sudden, I saw my screen started moving back and forth. And I just sat there and I backed up off my chair … (it) lasted for 3 to 5 seconds.”

According to local officials, no damage has been reported as a result of the quake.
