A 5.9-magnitude earthquake has struck about 160 miles off the Oregon coast, but there are no reports of damage.

The quake was reported at about 3:40 p.m. local time Wednesday, west-northwest of the coastal city of Bandon, Ore.

The West Coast and Alaska Tsunami Warning Center says no tsunami is expected.

Doug Gibbons of the U.S. Geological Survey says the earthquake is not related to two massive earthquakes in Indonesia on Wednesday.

Gibbons says the earthquake was about 8 miles below the earth's surface.
