Concrete, WA – A magnitude 2.5 earthquake was recorded Tuesday morning just west-southwest of Concrete in Skagit County, according to seismic monitoring agencies.
According to the Pacific Northwest Seismic Network (PNSN) and the University of Washington, the quake struck at 8:06 a.m. PST (15:06 UTC) on Tuesday, with an extremely shallow depth of 0.2 kilometers, which can increase the chance of light shaking near the epicenter.
The earthquake was centered approximately 4 kilometers (2.5 miles) west-southwest of Concrete, about 70 miles north of Seattle, placing it within a region that frequently experiences small seismic events tied to local fault systems.
As of Tuesday morning, no injuries or damage had been reported. The event was marked as reviewed, indicating scientists have confirmed the magnitude and location. Officials continue to monitor for aftershocks, though none had been immediately reported.
Because of its modest magnitude, the quake was unlikely to cause structural damage, but residents close to the epicenter may have noticed a brief jolt or rumble, especially given the shallow depth.
The USGS and PNSN encourage residents who felt the shaking to submit a “Did You Feel It?” report, which helps researchers better understand how earthquakes affect communities across Washington.
Washington sits along the seismically active Pacific Northwest, where small earthquakes occur regularly and serve as reminders of the region’s larger seismic risk.
