I thought I felt a little jiggling just north of downtown Seatt;e, but it wasn't strong enough to knock over even the most delicately balanced object or make any rattling noises in the house. So yes, I felt it, but it caused no damage.
Compare that with the 7.0 (later downgraded to a 6.8) Nisqually earthquake in early-2001, which wasted just about everything I owned. /ubbthreads/images/graemlins/jpshakehead.gif
