WASHINGTON (Reuters) - A magnitude 5.9 earthquake struck off the coast of Oregon on Wednesday and was followed a minute later by a smaller quake off the coast of central California, the U.S. Geological Survey said.
The Pacific Tsunami Warning Center said the quakes were unlikely to trigger a tsunami. The Oregon quake was initially reported as a magnitude 6.2 and the California one as a 5.3. Both were later downgraded.
It was not immediately known whether the quakes caused any damage or casualties.
