SAN FRANCISCO (AP) — A 7.0 magnitude earthquake shook a large area of Northern California on Thursday, knocking items of grocery store shelves, sending children scrambling under desks and prompting a brief tsunami warning for 5.3 million people along the U.S. West Coast. The quake struck at 10:44 a.m. west of Ferndale, a small city in coastal Humboldt County, about 130 miles (209 km) from the Oregon border, the U.S. Geological Survey said. It was felt as far south as San Francisco, some 270 miles (435 km) away, where residents felt a rolling motion for several seconds. It was followed by smaller aftershocks. There were no immediate reports of major damage or injury. A tsunami warning was issued shortly after the temblor struck and covered nearly 500 miles (805 km) of coastline, from the edge of California’s Monterey Bay north into Oregon. (Photo: AP)
