If you felt a little rattled as you got ready for work this morning, you weren't alone: According to the US Geological Survey, that shaking you felt was an earthquake just off the San Francisco Coast.

According to the USGS, the 3.2 magnitude quake struck at 6:36 Tuesday morning off the San Francisco coast, with an epicenter just 6.8 miles northwest of the Zoo. It had a depth of three miles, the USGS says, and was located near the San Andreas Fault, according to CBS 5.

Local news outlets say that the shaking was felt across the area. According to KRON 4, "Viewers tell us they could feel rattling in San Francisco. Another viewer reported feeling a “strong jolt” in the inner Richmond District.

"Some people took to social media to report they felt shaking in places such as San Francisco and Pacifica," NBC Bay Area reports. "One person noted that the earthquake was 'short and sweet' while someone else reported feeling a jolt before a couple seconds of rattling."

Stephanie Recob of Daly City told the Chron that she felt “a jolt and then a few seconds of rattling in Daly City.”

According to the USGS's DidYou Feel It? map, the shaking was felt as far north as Novato, and as far south as Half Moon Bay.

No damage has been reported as a result of the earthquake, ABC 7 reports, and no tsunami warning has been issued. According to NBC, the San Francisco Fire Department says that so far, they haven't gotten any calls regarding the quake.

Update: The Chronicle reports via the USGS that a second quake of 2.7M struck an hour later at 7:32 a.m., with an epicenter a bit further north, 16 miles east of Shingletown in Shasta County.
