The temblor struck Monday night nearly 3 miles west of Dublin, according to the USGS.
DUBLIN – A pair of earthquakes rattled the East Bay on Monday night, according to the U.S. Geological Survey.
The first quake – a magnitude 3.9 – hit at 7:46 p.m. about 2.9 miles west-northwest of Dublin. A magnitude 2.9 quake then hit at 8:19 p.m. about 1.8 miles southeast of Pleasant Hill.
There were no immediate reports of injuries or damage.
BART reduced train speeds while tracks were inspected for damage, resulting in system-wide delays of up to 20 minutes. Normal service resumed around 8:50 p.m.
The first of the two earthquakes was initially reported as a magnitude 4.2, but the USGS later downgraded it to a 4.0 and then to a 3.9.
The USGS said the 3.9 quake was felt as far away as Modesto, Monterey and the Sierra Nevada foothills.
