"A string of earthquakes near the vulnerable San Francisco Bay Area erupted in rapid succession Monday morning, and even triggered California's tsunami alert system. The earthquake swarm started with a magnitude 3.8 quake at 9.27am ET, with the US Geological Survey (USGS) recording ten sizeable seismic events in just 40 minutes around San Ramon. Within two hours, USGS recorded more than 19 earthquakes stronger than magnitude 2.5, meaning they were all powerful enough for people to feel above ground."
"A magnitude 4.2 earthquake was detected at 10.01am ET, which sent noticeable shockwaves to nearby San Francisco, Sacramento, and San Jose. Residents in San Francisco's Glen Park and Nopa neighborhoods reported rumbling and 'windows rattling' during the quake, and public transportation throughout the area was also affected by the swarm, according to the San Francisco Chronicle. The moderate quake even activated the National Tsunami Warning Center, however, officials said there was no danger of a major wave hitting the Bay Area."
"San Ramon lies atop the Calaveras Fault, a major branch fault in the broader San Andreas Fault System, sparking fears the main fault line could be closer to a major rupture that locals refer to as 'the Big One.' The initial magnitude 3.8 quake was centered just 16 miles from Concord, 18 miles from Oakland, and 29 miles from San Jose, which are three of the most populated communities in the Bay Area, home to more than 1.5 million people."
An earthquake swarm began near San Ramon with a magnitude 3.8 at 9.27am ET, and USGS recorded ten sizeable seismic events within 40 minutes. Within two hours more than 19 earthquakes exceeded magnitude 2.5, making them perceptible at the surface. A magnitude 4.2 at 10.01am ET sent noticeable shockwaves to San Francisco, Sacramento, and San Jose, rattling windows and affecting public transportation. The event triggered California's tsunami alert system, but officials reported no danger of a major wave. San Ramon sits atop the Calaveras Fault, a major branch of the San Andreas system, and the initial quake was centered within roughly 16–29 miles of several large Bay Area cities. No injuries or property damage were reported.
