WOODBURN, Ore. - A magnitude 4.0 earthquake struck east of Woodburn on Wednesday evening, officials said. KGW reported its viewers reported shaking across the metro region.
The earthquake struck at 5:24 p.m., about 17 kilometers deep, according to the Pacific Northwest Seismic Network. The epicenter was directly east of Scotts Mills, a town of about 350 people in Marion County.
There have been no reports of damage yet, according to the Marion County Sheriff's Office.
An earthquake struck in nearly the same spot in 1993. That earthquake was called the "Spring Break quake" and had a magnitude of 5.6.
Seismologists expect at least a magnitude 8.0 earthquake hit the Northwest, with a one in three chance of "the big one" happening in the next 50 years. That earthquake is expected to cause widespread damage in Oregon and Washington.
