Another earthquake hits Pacific Northwest bringing total to 87 in past month

Early Friday morning, a 3.9 magnitude earthquake struck near Vancouver, British Columbia. The Pacific Northwest Seismic Network reported the tremor occurred about 2 a.m. in the Salish Sea, about 15 miles west of Vancouver.

The U.S. Geological Survey noted the quake originated 38 miles below the surface, causing mild tremors felt in Vancouver and on Vancouver Island. No immediate reports of damage or injuries were made.

If you experienced the earthquake, please report it to the USGS Earthquake Report.

In the past month, the Pacific Northwest has experienced 87 earthquakes of magnitude 1.5 or greater, according to earthquaketrack.com.

The good news is that it’s not necessarily an indication of a more severe earthquake. The bad news is a significant earthquake in the region is long overdue.

“An earthquake like this is going to shake the hell out of the coast,” Earth Sciences Information Officer for the Oregon Department of Geology and Mineral Industries, James Roddey, told the Bandon Western World.

Roddey said a recurring 9.0-average magnitude event is known as the Cascadia earthquake. It last struck the region in 1700, according to the USGS.
