PORTLAND, Ore. — A magnitude 5.9 earthquake has struck about 160 miles off the Oregon coast, but there were no reports of damage, and no tsunami generated.

The quake was reported at about 3:40 p.m. local time Wednesday (12:40 p.m. HST), 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.

Two powerful earthquakes struck within 12 hours yesterday in Mexico. Around 9 p.m. Wednesday (HST) a 6.9 quake hit in the Gulf of Mexico near Guerro Negro. The earlier quake was centered in unpopulated mountains between Mexico City and Acapulco. That quake measured 6.5. Neither temblor sent a tsunami.
