Mount Vernon, Washington – A minor earthquake shook parts of Skagit County early Tuesday morning, waking some residents near Mount Vernon and the U.S.-Canada border. The 2.9 magnitude tremor struck at 1:59 a.m. PDT, about 3 kilometers west of the city, according to the Pacific Northwest Seismic Network.
The quake was centered at a depth of 8.7 kilometers and was reviewed by seismologists at the University of Washington. While light, it was widely felt throughout the Mount Vernon area, with at least five reports submitted through the USGS “Did You Feel It?” system. The shaking was classified as intensity level IV, indicating light shaking and no expected damage.
No major disruptions have been reported, but the early morning jolt served as a reminder of the region’s seismic sensitivity. Residents near the Canadian border—including in Burlington, Sedro-Woolley, and northern Whidbey Island—may have experienced light vibrations or a brief rumble.
Officials recommend checking emergency kits and reviewing home earthquake safety plans, especially for residents living near known fault zones in western Washington.
No aftershocks have been recorded as of Tuesday morning, but seismologists will continue to monitor the area throughout the week.
