3.4 Magnitude Earthquake Rattles East Bay Day After M4.5 Temblor

Update: 7:25 p.m. Tuesday: A 3.4 magnitude earthquake rattles the same area north of Walnut Creek where a larger 4.5 magnitude quake was centered Monday and felt across the Bay Area.

A 4.5 magnitude earthquake struck near Walnut Creek late Monday night, according to the USGS.

The quake, which struck at 10:33 p.m. and was centered 0.7 miles south-southeast of Pleasant Hill and 2.2 miles north of Walnut Creek, was felt across the Bay Area. A smaller 2.5 magnitude temblor shook the same area just a few minutes before, the USGS said.

Late Tuesday, a 3.4 aftershock rattled the same area, the USGS said. That quake hit at 7:12 p.m.

Andrew Lozano lives near the epicenter of the Monday quake and was asleep when it hit. He said he felt "a pretty strong jolt," adding that the shaking lasted about five to seven seconds.

No injuries or significant damage were immediately reported, but some stores in the Pleasant Hill area reported items falling off shelves. Photos from inside a Safeway in Pleasant Hill showed items such as lotion, soap and wine bottles, some damaged and leaking, lying on the ground.

The 4.5 magnitude quake struck at a depth of about 9 miles, according to the USGS. The epicenter was located between the southern part of the Concord Fault and the northern part of the Calaveras Fault.

The USGS reported several aftershocks measuring under 2.0 in the minutes after the temblor.

BART trains were slowed immediately following the earthquake to allow for rail inspections. Those inspections have since wrapped up.
