7 Earthquakes Reported Off The Coast Of Oregon In The Last 24 Hours

Scientists say a cluster of 7 earthquakes ranging in magnitude up to 5.9 have struck off the coast of the Pacific Northwest, but haven’t been strong enough to generate tsunamis. The sixth and seventh quakes in the series struck Monday evening. They were the weakest so far, at magnitude 3.9 and 4.2. The quakes have been shallow – about 6 miles deep. They’ve been clustered in an area about 300 miles west of Coos Bay, Oregon, along what’s known as the Blanco Fracture Zone. U.S. Geological Survey scientist Julie Dutton says that’s a well-known place for earthquakes. The first quake came a few minutes before midnight Sunday, Pacific time, at magnitude 5.8.
