A series of three earthquakes with magnitudes of 3.9, 2.8, and 3.0 struck San Ramon in the Bay Area on Saturday evening, felt in Oakland and San Francisco, but caused no injuries or damages. This follows a recent cluster of seismic activity in the area earlier in the week.
San Ramon experienced a series of at least nine earthquakes, with the largest being a 4.0 magnitude, due to complex fault interactions and fluid infiltration in the area, which has been hit by nearly 150 quakes in the past month.
A series of at least six earthquakes, including a magnitude 4.0 quake, struck the San Ramon area on Friday night, causing local alarm but no damage. The seismic activity is part of a larger swarm that has been ongoing for days, with experts noting that such swarms are usually not indicative of an imminent larger quake and are often caused by fluid interactions or slow fault slipping.
All southbound lanes of Highway 680 in San Ramon have reopened after being blocked due to a barricaded and armed suspect. The suspect was detained by CHP without a gun being found, and was taken into custody for driving under the influence of drugs. Two minor vehicle crashes were also reported.
An Amazon delivery driver in San Ramon was kidnapped by a man and a woman after a vehicle collision. The woman forced the victim to drive to a Bank of America in San Ramon, where they made him withdraw cash. They then forced him to drive to another Bank of America in Dublin, but the transaction did not work, so they left him there. The driver contacted his boss before calling the police, and Amazon stated that they are glad the driver is safe. The San Ramon Police Department is continuing to investigate the incident.
