4 major earthquakes strike along West Coast, Mexico in last day
On Wednesday afternoon, a magnitude 5.9 earthquake struck in the Pacific Ocean about 160 miles west of the coast of Oregon, the U.S Geological Survey said, but no tsunami developed.
The Oregon earthquake, which occurred at 3:42 p.m., appeared to be centered near where seismic plates intersect.
A second, much larger quake, registering 7.0, was felt near Michoacán, Mexico, a few minutes later.
None of the quakes caused significant damage or injuries, and no tsunami warnings were issued.
