3.1 Magnitude Earthquake Hits Berkeley Near Previous September Quake Sites

A minor earthquake of magnitude 3.1 struck Berkeley on Thursday morning, causing tremors across the East Bay region. The U.S. Geological Survey reported the quake occurred at approximately 9:23 a.m.

Location and Previous Activity

The earthquake’s epicenter was located in the hills near the main campus of the University of California, Berkeley. This area was the site of a larger 4.3-magnitude quake on the Hayward Fault last month, followed by a 3.0 aftershock. It remains unclear if the recent quake is connected to these previous events.

Impact on Public Transport

Following the tremor, BART riders traveling on a Yellow Line train in West Oakland experienced brief interruptions as the transit agency conducted checks for seismic activity.

Coincidence with Earthquake Preparedness

Interestingly, Thursday’s quake happened less than an hour before the scheduled International ShakeOut Day drill, slated for 10:16 a.m. This annual exercise aims to increase awareness and preparedness for handling major earthquakes.
