Small quake rattles Willamette Valley
A small earthquake rattled the Willamette Valley Wednesday afternoon.
The Pacific Northwest Seismic Network reported that a 4.0 magnitude quake struck at about 5:24 p.m. Dec. 13, near Scotts Mills, about 13 miles east of Woodburn.
No major damage from the quake was reported.
The earthquake was along the Canby-Molalla fault, one of several northwest faults that crisscross the Portland area. The fault produced the 1997 5.6-magnitude Scotts Mills earthquake that shook the region early in the morning. It also produced a 5.2-magnitude quake in 1962 that shook Vancouver, Washington.
According to the U.S. Geological Service, the Portland area has experienced five earthquakes of magnitude 5.0 or greater in 150 years.
