A minor earthquake with a 3.1 magnitude was recorded at Monday morning in the Portland region. The Pacific Northwest Seismic Network reports the quake at 6:15 a.m. was centered about 11 miles northwest of Portland and was relatively deep, at 12 miles.
It was felt in in the outlying towns Scappoose, Oregon City and Woodburn in Oregon and in Vancouver, Brush Prairie and Ridgefield in Washington state.
Geologist Scott Burns at Portland State University told KATU-TV the quake may be related to a smaller quake Sunday of 2.3 magnitude. Burns said quakes stronger than 2.5 can generally be felt.
"It reminds us we live in earthquake country and that we need to be prepared," Burns said. But he said the Monday quake should produce little if any damage.
