I'd rather live here (S. calif) than Seattle. They are overdue for a big one. Every 300 years or so. And Mount Rainier could blow simultaneously. The last big quake they had was ~350 years ago (dated from geological records).
I've seen magnitude estimates of 8.5-9.5. This would seriously damage Bill Gates' property values.

Seriously, though, the Pacific Plate keeps turning and we can expect techtonic and volcanic activity at any time anywhere along the Pacific Coast.
Heck, just for fun, I'll post the current earthquake map for California.
It was dated from records of aa giant tsunami in Japan as 1699 and caused great sinking and upheavels all along the NorthWesr coast. Indian legends abound about it. Core samples taken here in Humboldt Bay (Eureka) and Crescent City show sediment almost 2 feet thick. As a comparison the Crescent City Tsunami in 1961 that killed several people and did millions in damage left sediment 3 inches thick. This event was caused by the great Anchorage quake .
