7.0 magnitude quake off North California prompts brief tsunami warning

A 7.0 magnitude earthquake shook a large area of Northern California on Thursday, knocking items off 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.
