USGS: Northern CA temblor unrelated to Baja quake

SAN FRANCISCO — A geophysicist with the U.S. Geological Survey says an earthquake recorded Sunday afternoon in Northern California was not related to a quake that hit south of the U.S.-Mexico border earlier in the day.

The USGS says the Northern California quake, with a magnitude of 4.0, hit about 25 miles north of Santa Rosa at 3:49 p.m.

Geophysicist Rafael Abreu described the Northern California quake as “typical seismic behavior” for the area.

A dispatcher with the Sonoma County Sheriff’s Department, in Santa Rosa, says he didn’t feel the temblor and the department hasn’t received any calls for service related to the quake.

Santa Rosa is about 50 miles north of San Francisco.

SAN FRANCISCO (AP) — An earthquake with a preliminary magnitude of 4.0 has been recorded in Northern California.

The U.S. Geological Survey says the quake hit at 3:49 p.m. Sunday about 25 miles north of Santa Rosa. Santa Rosa is about 50 miles north of San Francisco.

The area frequently experiences small earthquakes, and there was no indication the earthquake was an aftershock from the larger quake that struck in Baja California, Mexico, on Sunday afternoon.

A dispatcher with the Sonoma County Sheriff’s Department in Santa Rosa said he didn’t feel the quake and that the department had not received any calls for service after the quake.
