The U.S. Geological Survey reported a 3.5 magnitude earthquake near Coulee City at 8:48 a.m. Monday. The earthquake was 2.6 miles deep.
No damage was reported, according to the Grant County Sheriff’s Office.
“For a magnitude 3.5 or so like that, I would not really expect any damage,” said Harold Tobin, Pacific Northwest Seismic Network director. “I would expect people in the region relatively close to it to feel it, and I’ve heard a little bit of people making self-reports, but not a huge amount so far.”
To track self-reports, Tobin checks USGS’ “Did You Feel It?” map. By Monday evening, nine people had submitted information for the map.
The earthquake had an epicenter west of the reservoir and southwest of Grand Coulee Dam.
Tobin said that while it’s important to always be prepared for earthquakes, this one should not cause any undue alarm.
