A magnitude 4.6 earthquake shook Seattle and the Puget Sound region just before 3 a.m. Friday, according to the United States Geological Survey. “It’s been widely felt throughout the Seattle area,” said Paul Caruso, a USGS geophysicist. The shaking emanated from Three Lakes, Snohomish County, about nine miles east of downtown Everett. The earthquake was relatively shallow, originating about 14 miles beneath the surface, according to a USGS map. At most, the earthquake lasted a “couple seconds,” said Joan Gomberg, a USGS seismologist and affiliate faculty member at the University of Washington, though shaking can feel longer “because some houses reverberate a little bit.” There were no immediate reports of damage in Snohomish County, according to a tweet from the Sheriff’s Office. Police in nearby Lake Stevens reported no damage to city infrastructure. The Washington State Department of Transportation said in a tweet that the agency would be inspecting bridgesFriday morning, but had no reports of damage.
