Magnitude 5.9 quake hits off Oregon coast

A 5.9 magnitude earthquake struck on Saturday at 10:44 a.m. ET off the U.S. northern Pacific coast of Oregon, the U.S. Geological Survey said.

The quake was centered 112 miles west of Port Orford, Oregon, at a depth of 6.2 miles, according to Angel Gutierrez, a geophysicist with the USGS in Golden, Colorado.

The USGS initially put the quake at 6.0 magnitude.

The quake was relatively shallow, about 6 miles down, and no tsunami alert was issued as a result, Gutierrez said.

Minor earthquakes are common in that region of the Pacific Ocean, along the Cascadia subduction zone.
