That's a scary prospect, though possibly soon a very real one. I would anticipate a large E.Q. to spur the volcanoes into action, maybe N cal Mendo3x or maybe the much dreaded Cascadia rupture, which would certainly mean a lot of trouble for this whole side of N. America, BIG E.Q., then BIG TSUNAMI, then Volcanoes immediately erupting, then Lahars, not to mention the small HUMAN factor that could also present some danger(looters etc). SURE could wait a while for that one and be happy about it! Thanks Petra, let's talk more soon...before the volcanoes butt in...mb. Enjoy!
