San Francisco, California – Two small earthquakes struck just south of the San Francisco Zoo late Saturday night, occurring within minutes of each other and briefly shaking parts of the coastal Bay Area.
According to the U.S. Geological Survey, the first earthquake, a magnitude 2.7, hit at approximately 11:41 p.m. UTC about 3 kilometers south-southwest of the zoo at a depth of 6.9 kilometers. Just minutes later, a second, slightly stronger magnitude 3.0 quake was recorded at 11:39 p.m. UTC in nearly the same location, at a depth of about 7.0 kilometers.
The back-to-back tremors were centered along the Pacific coastline in San Francisco County, near the Daly City and Pacifica areas within the greater San Francisco Bay Area. Residents in nearby neighborhoods reported light shaking, though intensity levels remained low.
No injuries or damage have been reported as of Saturday night. Small earthquakes of this magnitude are common in Northern California and are typically not strong enough to cause structural damage, though they can be felt near the epicenter.
Seismic activity in the region is closely monitored due to its proximity to major fault systems, including the San Andreas Fault. Experts say minor clusters like this can occur without signaling a larger event but are still tracked for patterns.
Authorities encourage residents to review earthquake preparedness plans, especially in seismically active regions like coastal California.
