San Francisco Bay Area is struck by a 5.1-magnitude earthquake.

On Tuesday, a 5.1-magnitude earthquake shook the San Francisco Bay Area, delaying several commuter trains. No damage or injuries were immediately reported.

The earthquake that occurred at 11:42 a.m. was centered 12 miles (19 kilometers) east of San Jose at a depth of roughly 4 miles, according to the U.S. Geological Survey (6 kilometers). About 40 miles (64 kilometers) southeast of San Francisco’s central business district lies a hilly region.

According to Lucy Jones, a seasoned seismologist in California, the earthquake occurred on the Calaveras fault, one of eight significant faults in the Bay Area, according to KNTV-TV.

Smaller earthquakes frequently occur along the Calaveras fault, according to Jones.

According to Jones’ social media post, it was the worst earthquake to hit the Bay Area since a 6.0-magnitude shock in Napa wine area in 2014.

According to Jones, the San Andreas fault’s main branch, the 138-mile (220-kilometer) Calaveras fault, stretches from San Juan Bautista in the south to San Ramon in the north.

According to Annemarie Baltay, a seismologist with the U.S. Geological Survey, several mild earthquakes, including the 6.2 Morgan Hill earthquake in 1984, have happened along the Calaveras fault.

The “long and steady” earthquake that occurred on Tuesday was felt in the kitchen of Rich Constantine’s home in Morgan Hill, a community close to San Jose.

Everything was trembling as a frame in the home fell, but once it stopped, there was no damage, the man claimed.

Constantine said that while Morgan Hill City Hall and other city buildings were evacuated, everyone quickly went back to work.

People who live near the expansive Joseph Grant Ranch County Park reported feeling the earthquake as far south as the picturesque Big Sur coast, which is 75 miles (120 kilometers) from the epicenter.

According to the California Governor’s Office of Emergency Services, or Cal OES, almost 100,000 individuals reported receiving a warning before the shaking began through the state’s earthquake early warning system.

According to the organization, the advance warning time ranged from two seconds for people in close proximity to the epicenter to 18 seconds for people in San Francisco.

A system for earthquake detection and alerting created by the U.S. Geological Survey and collaborators is the foundation of MyShake, a statewide smartphone app that went live to the general public in late 2019.

The U.S. Geological Survey reports that a 3.1 aftershock occurred about 5 minutes later.

Trains from a number of commuter rail companies, including Cal Train and the Bay Area Rapid Transit system, or BART, were stopped so that damage could be inspected. By early afternoon, BART was operating normally again.
