Quick Summary

Sunday morning in California saw two earthquakes, with a 3.5-magnitude quake followed by a 2.6-magnitude tremor about twenty minutes later, felt from San Jose to Walnut Creek. These quakes are part of increased seismic activity recently recorded across the state, including more than sixty low-magnitude earthquakes reported over one weekend in Southern California. Seismologists warn that while these latest events were relatively small, they underscore the potential for a major earthquake along fault systems like the San Andreas, which could severely disrupt critical infrastructure and affect millions of residents.

Story summary

Two earthquakes struck California on Sunday morning: a 3.5-magnitude quake hit around 7:20 AM, followed by a 2.6-magnitude tremor roughly 20 minutes later. According to the United States Geological Survey, the shaking was felt from San Jose to Walnut Creek and reflects an ongoing increase in seismic activity across California. Over 60 low-magnitude earthquakes were recorded over one recent Saturday, mostly below magnitude 2.0. Recent notable quakes include a 3.1-magnitude earthquake near Compton on September 17, felt in nearby areas like Long Beach and Downey. Scientists continue to warn about the potential for more significant seismic events despite not being able to predict exact timing, highlighting the risk posed by the San Andreas Fault.
