The National Earthquake Information Center in Golden, Colo., reports a magnitude 4.9 quake Friday night off the Oregon coast. There were no immediate reports of it being felt or causing damage.

Geophysicist Randy Baldwin says the quake was centered about 330 miles west-southwest of Portland at a depth of six miles - shallow in earthquake terms.

He says quakes of that magnitude are common in that area, part of the Juan de Fuca Plate, and there is no danger of it generating a tsunami.

The quake hit at 7:53 p.m. PST. The earthquake information center is part of the U.S. Geological Survey.
