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.
