I also live on the U S West coast (Seattle area). We get lots of quakes, little ones that rattle the dishes and once in a while a larger one. Biggest I've been through here was about 7.0. I was at work in a hundred year old building, on fill near the harbor. It gave us a good shake, and the facade of the building across the street fell off and landed on the road.
It left all of us rattled for a couple days.
