A 4.1-magnitude earthquake shook the San Francisco Bay Area at around 9:29 a.m. Wednesday, according to the U.S. Geological Survey (USGS).
The earthquake was recorded 4 kilometers south-southwest of Isleton, in Sacramento County, around 65 miles away from San Francisco.
USGS initially said the earthquake measured a magnitude of 4.5 before later downgrading it to a magnitude of 4.1.
The Standard staff felt the earthquake in the city in the Russian Hill, Ingleside and Duboce Triangle neighborhoods.
At Java Jack’s Cafe in Isleton, Jack Doelscher said they felt the quake.
“Oh, it was a good rocking,” Doelscher said. “But we survived.”
Damage reports were not immediately available. The City of Isleton Fire Department was contacted for comment but did not immediately respond.
The earthquake came a day before the Great California Shakeout test, confusing some whose MyShake app alert went off on their phones on Wednesday morning.
BART announced it would conduct track inspections following the earthquake, holding trains until inspections are complete. Delays of under 10 minutes are expected, the transit operator said.
This is a developing story.
