An earthquake and aftershock have been reported off the coast of south-central Oregon.

The United States Geological Survey says an initial quake with a preliminary magnitude of 6.2 struck just after 1:30 a.m., more than 170 miles (264 kilometers) west of Coos Bay, about 220 miles southwest of Portland.
  Â
Robert Sanders of the USGS says there is no tsunami threat associated with the quake. He says people as far away as Portland reported feeling the tremblor.
  Â
Dispatch with the Coos Bay police says there have been no reports of damage or injury.

The quake was located at a depth of about 6 miles (10 kilometers).

About two hours later, an aftershock with a preliminary magnitude of 3.5 struck the area.
