September 7th Earthquake Felt From Portland to Salem

Shortly before 10:00 pm on Friday, September 7th, the region known as Scotts Mills, Oregon, near Woodburn, was again shaken by an earthquake.  This crustal quake was on the same fault that carried the Spring Break quake of March, 1993.  That earthquake, measuring a magnitude 5.6, did some considerable damage to the area, including damage to the State Capitol building in Salem. Parts of the Capitol building were closed for repair for 2 years while the building was seismically retrofitted with additional concrete and steel bars.  This recent September quake, a magnitude 3.5, was not big enough to do any significant damage, but was felt from near Salem to just north of Portland.
