Unfortunately, Washington state is probably next. I have family there. In fact, one of my uncles is clearing out his belongings and trying to get things in order to leave Seattle specifically because of what happened in Japan.
I'm not sure science is good enough to tell us exactly where the large EQ is going to happen. But for sure, Seattle is "in the zone".
I too have family there. My mon, my sister and her family, and my brother. It will be catastrophic. I've made mention of this many times to them.
What I get back is variations on a theme.
"It won't happen." "It won't happen here!" "It won't happen to us." And the like.
So be it....they have the knowledge....and they've made their choice.
