PIEDMONT (CBS SF) — Mother Nature jolted East Bay residents out of their beds for a second straight day as a 3.5 magnitude earthquake struck the Hayward Fault near Piedmont, authorities said.

According to the U.S. Geological Survey, the temblor struck at 6:11 a.m. 3 miles north of Piedmont. Nearly in the same spot as Wednesday’s 3.4 magnitude quake that struck near Tunnel Road and Highway 13.

The quake was felt most strongly in Berkeley and Oakland, but residents in San Francisco also reported a strong jolt.
