As one of my friends from UK says: "Seattle looks like...London but with a Mountains..."
Volcanoes, Earthquakes is a natural thing and we are learning to live with our old Neighbors. ( Adams, MSH, Tacoma...)
In my opinion the most positive things here is a Light Railway.
Seattle is an extremely underrated world class city. Walkable, clean, safe, great schools, etc. Even a great football team!
I would move there in a heartbeat, except for the looming ultramassive earthquake that will kill everyone.
