A magnitude 3.8 earthquake in Oakland shook Berkeley on Thursday morning, according to early reports.

The quake’s epicenter was on Calandria Avenue near Interstate 580.

It was recorded at 8:30 a.m. with a depth of 3.2 miles, the U.S. Geological Survey reported.

The earthquake originally registered as magnitude 4.1 but was downgraded twice after review.

Writing on the UC Berkeley Reddit, one person said they felt “Side to side strong rocking in my part of Berkeley, but nothing fell over.”

Another described it as “A mild shake.”

Two aftershocks were recorded after the original earthquake, the U.S. Geological Survey reported: with initial readings of magnitude 3.0 and magnitude 2.8, both at 9:07 a.m.

This story was updated as more information became available.
