The U.S. Geological Survey reported that a series of small earthquakes, including a 1.7-magnitude quake and a 1.2-magnitude trembler, shook Berkeley, California in less than 24 hours. Another 1.6-magnitude earthquake also struck the East Bay area south of Walnut Creek. No injuries or damage were reported from any of the quakes.
Why it matters
While the magnitudes of these earthquakes were relatively low, they serve as a reminder of the seismic activity in the Bay Area and the need for residents to be prepared for potential larger quakes in the future. Small tremors can sometimes be precursors to more significant seismic events.
The details
According to the USGS, the first 1.7-magnitude quake hit Berkeley around 6 PM on Thursday. The second 1.2-magnitude trembler occurred at 3 AM the following morning. Additionally, a 1.6-magnitude earthquake struck an area 2 miles south of Walnut Creek at 12:46 AM. Authorities reported no injuries or property damage from any of the seismic events.
