Several small earthquakes occurred within minutes of each other near San Ramon and Daly City on Tuesday afternoon, according to the U.S. Geological Survey.
The quake was centered about 2 miles east of San Ramon and had a depth of 4.8 miles, according to the USGS.
Some staff members in Danville's Town Hall felt the quake, although it lasted for "all of a second," town spokesman Geoff Gillette said.
Five minutes later, a 2.1-magnitude quake was recorded near Broadmoor, and was quickly followed by a 2.8-magnitude earthquake in the same area. Broadmoor is located near Daly City.
At 3:53 p.m., a 1.4-magnitude quake occurred in that spot, according to the USGS.
Those quakes were centered about 3 miles south-southwest of Broadmoor.
Tuesday's earthquake in San Ramon was one of three recent quakes that could be felt by residents. Two others occurred on Nov. 8 and 9, and the USGS counted 18 small tremors in the last week.
