California experienced a series of earthquakes in less than 12 hours, including a 2.8 magnitude tremor that struck Monterey County.
The two earlier quakes near San Francisco, measuring 2.8 and 2.9 magnitudes, were felt by nearly 2,000 people.
No injuries or major damage were reported, though experts continue to monitor the region.
These quakes occurred along the San Andreas Fault, which spans the state and is known for potentially devastating tremors.
Experts fear the fault is overdue for a larger earthquake, with a “Big One” expected to affect over 39 million people.
California has experienced over 10,000 quakes this year, most of which are minor, but the constant tectonic plate movement under the state fuels this ongoing seismic activity.
