Loomis, WA – A minor earthquake was recorded early Saturday near the Washington–Canada border, according to updated data from the U.S. Geological Survey. The magnitude 2.7 quake struck about 8 kilometers east-southeast of Loomis in Okanogan County.
According to the USGS, the quake occurred at 9:36 a.m. UTC on Saturday, registering at a depth of 10 kilometers. Although considered a small event, it was strong enough to be felt locally, with at least three people submitting “Did You Feel It?” reports to the agency.
The quake’s epicenter sits just south of the international border and west of the Okanogan River Valley, an area that occasionally experiences low-level seismic activity. No damage or injuries were reported, and USGS officials note that earthquakes below magnitude 3.0 rarely cause structural impacts.
Light shaking was reported in nearby rural communities, though the tremor likely went unnoticed by many residents. The region has seen intermittent seismic activity in recent weeks, according to USGS nearby-seismicity records, which track quakes of magnitude 1.0 and above within a 250-kilometer radius.
Earthquakes in northern Washington are typically linked to a complex network of crustal faults stretching across the North Cascades and into British Columbia. While Saturday’s quake was minor, USGS encourages residents—especially those living in rural or mountainous areas—to remain aware of seismic hazards and ensure basic emergency kits are up to date.
No aftershocks have been reported as of Saturday morning, and seismic activity is expected to remain low. The event has been reviewed and confirmed by the USGS National Earthquake Information Center.
Residents who felt the shaking can contribute to the USGS citizen-science database by submitting a report on the agency’s website.
