WILLOW CREEK (CBS/AP) — Earthquakes shook northern and southern regions of California early Thursday.

A U.S. Geological Survey computer generated report said a magnitude-3.9 quake struck at 3:39 a.m. Thursday about 10 miles south of Willow Creek in Humboldt County, some 300 miles north of San Francisco.

Nearby Hoopa police Officer Karl Norton said a resident called and wondered if it was a quake, but there are no reports of damage.

In the south along the U.S.-Mexico border, a magnitude-3.3 quake centered 36 miles south-southeast of Calexico was reported at 1:50 a.m. Thursday. Calexico is 120 miles east of San Diego in Imperial County.

A Calexico police dispatcher said she didn’t feel the quake and there were no calls.
