4 major earthquakes strike along West Coast, Mexico in last day

The West Coast of the United States and Mexico have been hit by a series of powerful earthquakes in the last day.

The latest was a  magnitude 6.9 earthquake that shook Baja California early Thursday morning, the U.S. Geological Survey reported.

The earthquake, which occurred at 12:15 a.m., was centered about 360 miles southeast of San Diego, on the western edge of the Gulf of California.

A smaller quake, a magnitude 6.2, shook the same area at 12:06 a.m.

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.
