Small quakes rattle East Bay, Napa
A junior-sized earthquake jounced the small East Bay community of Piedmont early Sunday morning but did no serious damage, the police and fire departments said.
Scientists at the U.S. Geological Survey said the epicenter of the quake, which struck about 3:35 a.m., was 1 mile northeast of Piedmont. The disturbance started about 4 miles below the surface and registered a magnitude of 3.4.
Earlier, at 1:43 a.m., an earthquake with a magnitude of 4.1 struck 9 miles north of Napa. It was followed at 7:47 a.m. by a micro-quake measuring 2.2.
``They are relatively minor in nature and not uncommon for California,'' said Eric Lamoureux, a spokesman for the Governor's Office of Emergency Services. During the last seven days there have been 355 earthquakes throughout the state and more than 100 in the Bay Area, he said.
