Seattle is another area I would worry about as far as preparedness for a Major earthquake. Most of the new skyrises are probably safe, but the Alaskan Way Viaduct would most certainly collapse (it was nearly destroyed due to a moderate eathquake 10 years ago, but due to local politics no suitable replacement/repair has been made), as would most of the waterfront, whose foundations have been eaten away by something I've heard called 'gribbles.' Additionally I would worry about many of the much older buildings downtown, which have also been damaged before by moderate earthquakes.
