Northern California coast was rocked by massive magnitude 7 earthquake on Thursday that led to a tsunami warning for an extensive stretch of coastline along California and Oregon, according to officials.
The quake, which hit at a shallow depth of 10 km (6.2 miles), was centered about 39 miles (63 km) west of the town of Ferndale, a sparsely populated portion of the northern California coast, the US Geological Survey said.
The National Tsunami Center issued a warning for a long stretch of the US West Coast, from Dunes City, Oregon, south to San Francisco and San Jose, California, 400 miles (643 km) away.
San Francisco and a large area of the surrounding Bay Area were under the tsunami warning.
