I can't remember where I read it, but because the PNW is a subduction zone, the last time there was a big quake 300 years ago there were some spots (like Whidbey) that raised/lowered 30 feet, and Willapa Bay changed a significant depth. Similar things happened up in Alaska during their Good Friday quake.
My question is, are there any estimations on which areas around Puget Sound might raise/lower and have a higher risk of permanent flooding after the quake?
