There is a difference between being risk adverse and stupid. I'm one of those rare people that isn't afraid of anything... literally. I'm freakish that way. I have no problems with people wanting to live in dangerous places, I just find it hard to give them my sympathy when they've been hit several times and still won't move. It's dumb to put your life in danger intentionally and it's dumb financially to build your home in a high risk area. Here's the thing... if you live in a psuedo dangerous area and you've had no problems then stay. As soon as you get wiped out though... it's time to frikkin move. "Lightning strikes twice" is a horrible saying, because it strikes twice all the time! Metaphorically speaking of course.
I don't get your logic either. I'm sitting here trying to think of a single place in the world that is hurricane, earthquake, tornado or volcano prone (and I mean REALLY prone, not this you get a little bit of nothing once in a while or it might erupt 300 years from now) I'm coming up empty.
The beach is a horrible place to live. Sure it's nice to vacation there, but the salt and sand gets in everything, it's hot all the time, you have to deal with idiot tourists. No thank you. Then you've got LA, our resident earthquake hot-spot. Bad traffic, even worse pollution AND you've got all the hassles of living near the ocean on top of that. Again, no thank you. The midwest is tornado alley... enough said on that one.

I can't really think of any nice places to live under a volcano.... Hawaii is nice, but most of the main islands are no longer active. You've got Mt. Fuji, but it isn't really active either... heck it's a popular toursit activity to hike to the top.
About the only nice place to live that fits your description is Japan. I've got a fondness to Japan... but I've never visited, so I might hate it once I get there. Like the other places on the list it looks really good on tv and in film... once you actually get there though... well let's just say I'll stick to my mountains even if they are being rapidly destroyed by mountain top removal.

Don't misunderstand, I really get the sentimental attachment to where you grow up, I'm still living in the same place after all of these years. But when thinking of where I'd actually be willing to move, none of these danger zones come into mind... it's not even the risk, they just don't seem like nice places to live.
