There were actually three separate tremors just before noon Wednesday, and Earthquake Twitter was feeling it.
Yes, you did feel an earthquake, if you felt it at about 11:45 a.m. Wednesday morning. According to the U.S. Geological Service, a 3.9-magitude earthquake hit just north of San Ramon late Wednesday morning. It was initially diagnosed as a 3.8, but that figure has since been revised.
An earthquake swarm hit Wednesday near Crow Canyon Country Club in southeast Danville. Twelve quakes ranging in magnitude from 1.3 to 3.8 struck between 11:43 a.m. and 12:27 p.m. https://t.co/ZNrVuylWeZ via @nik_shine @SFBay pic.twitter.com/SgTioA06Xt— SFBay.ca (@sfbay) November 17, 2021
There were also two aftershocks, at 11:46 and 11:58 a.m., the latter of which registered a 3.0-magnitude.

Rosie from Lafayette describes feeling the #earthquake this morning. She said it brought back memories of the 1989 earthquake. @nbcbayarea pic.twitter.com/UNEIolls6M
But a look at Twitter shows the quake was felt throughout the Bay Area, particularly in the Eat Bay, but also in San Francisco.
