4.1-magnitude quake near Concord rattles San Francisco Bay Area awake

A 4.1-magnitude earthquake shook the San Francisco Bay Area early Thursday, June 2, the U.S. Geological Survey reports.

The 12-mile deep quake hit near Bay Point, six miles from Concord, at 5:07 a.m. Pacific time, according to the USGS.

“Nothing like a minor earthquake to get the day started,” one resident wrote on Twitter. “Shook the house for approx 4-5 seconds.”

“Can always count on Twitter to see if it’s an earthquake or a heavy truck going down the street,” read another Twitter post.

“Waking up and thinking someone is under your bed, nope, just an #earthquake at 5:07am thank you #California,” a resident posted to Twitter.

More than 3,700 people from as far away as Foresthill and Rescue reported feeling the tremor to the agency.

Concord, a city of 124,000 people, lies east of San Francisco.

Magnitude measures the energy released at the source of the earthquake, the U.S. Geological Survey says. It replaces the old Richter scale.

Quakes between 2.5 and 5.4 magnitude are often felt but rarely cause much damage, according to Michigan Tech. Quakes below 2.5 magnitude are seldom felt by most people.
