Original story: An earthquake with its epicenter in Kensington shook Berkeley at precisely 20 seconds past noon on Wednesday.

The US Geological Survey (USGS) registered the quake as a Magnitude 3.3. Its epicenter was 37.910°N  and 122.291°W — 2.5 miles NNW of Berkeley — with a depth of five kilometers.

There have been no reports of injuries or damage so far.


People took to Twitter almost as soon as the rumbling ended, including the City of Berkeley, and Mayor Jesse Arreguín, who reminded citizens to make disaster preparedness a priority.

The last time Berkeleyside reported a quake was on Sept. 13, 2016 when a Magnitude 3.5 near the Warren Freeway rattled residents early in the morning.
