Re: Denver, Seattle or San Fransico?
Well it was put together by a COC of Washington county in PA....isn't that where the Johnstown flood(s) took place? Maybe the COC wanted to gloss over some embarrasing facts.

Still it's a handy map to show what regions have what potential disasters. All they need to add now is flooding, wildfires, poisonous animals, and potential Al'Qaeda nuclear testing sites.
