So you'd move your entire life because there might be a natural disaster?
I can't even imagine how long it's been since you were in a city.
Have you ever been through a major earthquake? This was the week after we went through our earthquake that I was looking into it (and I am still living here 5 years later.) I couldn't get in touch with my (small) children and mother for hours and they were about 10 miles from the epicenter- and what I felt at 45 miles away was pretty major (turns out it was deep, so the distance didn't matter as much, but I didn't know in the immediate aftermath). All communications were down (syst overload) and I was not able to reach my then husband or my dad at work, either (dad's work had significant damage, we later found.) I finally found out my kids and parents were safe about 4 hours after it happened. So, yeah, I was just a little traumatized. Obviously, I have weighed the risks and my options and decided I am better off where I am.

I'm in a major city every day of the work week. I don't walk around afraid of life.
