A couple hundred people reported to the U.S. Geological Survey that they felt the tremors.
The Pacific Northwest Seismic Network (PNSN) reported two minor, overnight earthquakes near Bellingham and Bremerton.
Just before midnight, a 2.4 magnitude earthquake hit the Bremerton area near Wild Cat Lake.
At 1:40 a.m., a slightly stronger earthquake — with a magnitude of 3.0 — was measured about 5 miles outside of Bellingham. The quake was reported by 190 people in 11 zip codes as of 7 a.m. Thursday.
According to the U.S. Geological Survey, earthquakes measured under a magnitude 3 are felt by “very few under especially favorable conditions.” Earthquakes measured around or above a magnitude 3 are usually “felt only by a few persons at rest, especially on upper floors of buildings.”
