Series of Minor Earthquakes Shake California, Including Bay Area

Five earthquakes, the strongest at magnitude 3.7, struck California on Thursday, with multiple tremors centered near Hayward in the Bay Area.

California experienced five minor earthquakes on Thursday, with magnitudes ranging from 2.7 to 3.7, according to the US Geological Survey (USGS).
Three of the quakes occurred near Hayward, including a preliminary magnitude 3.7 tremor recorded at 1:59 p.m., the strongest of the day.
The Hayward Fault, a known seismic hotspot, was the epicenter for multiple tremors, which were felt in nearby cities such as San Francisco, Berkeley, and Fremont.
Two additional minor earthquakes were reported near Petrolia in northern California earlier in the day, continuing a week of seismic activity in the state.
No injuries or significant damage have been reported, but residents across the region reported feeling the tremors through the USGS's 'Did You Feel It?' tool.
