A 4.4 magnitude earthquake shook the Bay Area at about 6:40 p.m. Tuesday seconds before a 3.9 tremor—and just a couple days after a 2.9 jolted the region.
The U.S. Geological Survey recorded the epicenter of Tuesday’s larger quake somewhere about 4 miles north of Santa Rosa (opens in new tab), by the Rodgers Creek Fault (opens in new tab).
It was enough to knock liquor bottles from shop shelves (opens in new tab) and send people ducking for cover in Sonoma County, according to local press reports (opens in new tab).
It was also enough to trigger warnings from the ShakeAlert (opens in new tab) app, which sends notifications to subscribers about moderate-to-large earthquakes.
Almost as fast as the earth shuddered, “Earthquake Twitter (opens in new tab)” lit up in San Francisco and beyond.
“I got up and answered my door,” a user called @owenpeery (opens in new tab) tweeted, “i thought someone was knocking in my door, oh, it was an #earthquake (opens in new tab).”
“Rocked and rolled WAY longer than I care for,” @TheAuthorGuy (opens in new tab) wrote. “Hope everyone’s okay.”
About 760 Pacific Gas and Electric customers in Sonoma County lost power, according to the utility’s outage map (opens in new tab).
The Santa Rosa Fire Department, meanwhile, said (opens in new tab) it responded to multiple reports of gas leaks, alarms sounding and stuck elevators—but no injuries.
