Earthquake rattles Seattle area, 4.6 Magnitude one week after California, followed by series of aftershocks, Washington state overnight. Two earthquakes shook the Puget Sound region in Washington state early Friday morning, with the temblors felt into British Columbia and across the Cascade Mountains into the eastern part of the state.
The U.S. Geological Survey reports that a 4.6 magnitude earthquake rattled the Three Lakes area, about 40 miles northeast of Seattle. That was followed minutes later by a 3.5 magnitude aftershock near the city of Monroe, some 30 miles northeast of Seattle.
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.”
West Seattle Blog said that the quake "isn't huge but certainly the strongest in the region in quite some time," pointing out that it was the first quake "of at least 4 magnitude since February 2017."
The epicenter was near Three Lakes, Wa., about 35 miles north of Seattle, and tremors were felt across the Puget Sound region. There were no early reports of injuries and the U.S. Geological Survey (USGS) said there was no tsunami risk.
The shaking came from Three Lakes, Wash., about 40 miles northeast of Seattle, but could reportedly be felt all the way to the Canadian border.
A tsunami was not expected, according to a tweet by the U.S. National Tsunami Warning Center. Surveillance video obtained by KIRO-TV showed the moment the earthquake hit Everett, Washington.
