4.7-magnitude earthquake strikes off Oregon Coast; no damage reported


A 4.7-magnitude earthquake roiled ocean waters off the coast of Oregon Sunday.

The temblor struck at 5:49 p.m. about 196 miles from Bandon at a depth of just over 6 miles, according to the United States Geological Survey. There are no reports of damage or that anyone on land felt it.

The quake occurred along the Blanco Fracture Zone, a system of “strike-slip faults” off Cape Blanco in southern Oregon.

Earthquakes of magnitude 4.0-4.9 are considered “light.” Such quakes off the Oregon coast are common and suggest continued strain building along the Cascadia Subduction Zone.

Experts say there’s a 10-15% likelihood of a severe earthquake along the Cascadia Subduction Zone in the next 50 years. Such a quake might devastate much of the Oregon coast and cause significant damage in Portland.
