I'd never have expected to read "major world cities" and "Naples" in one=20 sentence :) I think if you go down to the "world" level of Naples, Italy, there are=20 many cities that don't expect a significant natural disaster. Naples has=20 only 1M habitants and besides that not much world significance, so you'd=20 have to include all cities with 1M+ habitants. Quite a few of them out=20 there... In Germany there are Berlin, Hamburg and M=FCnchen. I don't think any of=20 these expects a significant natural disaster -- unless the sea level=20 rises significantly, in which case Hamburg probably is affected. In Brazil, there are Bras=EDlia, Rio de Janeiro, S=E3o Paulo, and a number= =20 of less known cities (around ten or so, I think). I'm not aware of any=20 significant natural disaster waiting for any of them (of course, again=20 with the exception of possible significant sea level rise which would=20 affect the cities near the ocean -- of the three listed above, that's=20 only Rio de Janeiro).
