The Scotts Mills, Oregon earthquake on March 25, 1993

At 5:34 a.m. on March 25, 1993, much of northwestern Oregon and southwestern Washington was shaken by one if the largest historic earthquakes ever observed in the region. The Richter magnitude 5.6 earthquake occurred near the small town of Scotts Mills, 48 km south of Portland, Oregon. The March 25 earthquake was felt over a large part of the Pacific Northwest extending from Seattle, Washington, in the north to the town of Roseburg in southern Oregon. Due in large part to the moderate size of the event and its location in a rural setting, only minor injuries occurred, principally from falling objects and broken glass.
