So I live in California and in my LIFETIME (!) there have been less than half a dozen earthquakes that have caused a death and even then maybe just one. Sure they are unpredictable, but your chance of dying in one is slim. In reality, they are generally pretty fun, if I am lucky enough to not be sleeping.
I would really hate if I had to deal with disasters that came year after year. That just ups your chances. Most people can dodge earthquake damage their whole life, but if you live in tornado or hurricane country then chances are you or someone you know has been touched by it.
The actual problem that we face in California is forest fires, but since I'm not and IDIOT who built my $3 mil home in the dry brush hills, I don't have to worry about that.
Having forewarning is fine and dandy, but the devastation in New Orleans was a product of people not being able to leave. That's right, poor people without the means to evacuate and a government that literally locked up and failed to mobilize.
But I've got to look back a few hundred years and say that the people who decided that draining a swamp that had seasonal floods to build their city there were as stupid and the rich people who live in the California hills.
