New trio of earthquakes rumble under Berkeley

This post has been updated with a correction. See below for details.

A trio of earthquakes rattled Berkeley just as Saturday began, according to the U.S. Geological Survey. The aftershocks came just two days after a pair of quakes shook Berkeley, include one strong enough to knock items off  shelves. 

The first quake Saturday was  magnitude 2.8 and hit at 12:06 a.m., with its epicenter less than 100 feet south of the Claremont Hotel Club and Spa. A 1.3 aftershock hit at 12:14 a.m.in the same neighborhood, followed by a 2.5 quake at 12:45 a.m.

On Twitter, Berkeley residents chatted about the latest quakes. "Much weaker than [Thursday's], but enough to put me back on edge for the night," tweeted @AChanceFind. 

On Thursday, a pair of larger quakes rattled the region, a 4.0 in the afternoon and a 3.8 at night. The evening quake was large enough to cause some items to fall from shelves in some homes near the Berkeley epicenter, and some plaster fell from the ceiling of a business in Oakland, according to KRON-TV, KPIX-TV and the San Francisco Chronicle. [For the record, Oct. 22, 1:10 p.m.: An earlier version of this post incorrectly said the afternoon quake was magnitude 3.8 and the quake that occurred at night was 4.0.]
