Safer Survival Distance From USA City Hordes
July 28, 2010During a previous post, Survival Retreat Safe Distance From City, I promised that I would build a USA map of all 276 cities with populations greater than 100,000 people, and draw a 300 mile diameter zone around each city (150 mile radius). After a fair amount of effort, here it is. This will represent my opinion of a worst case disaster scenario where for whatever reason, the hordes are leaving the cities in search of xyz. The majority, at best, will get no further than 150 miles (see the referenced post as to why).
There are two exceptions to what you see on this map. Although I plan to make a project of improving the map, it currently does not reflect the effects of the location and direction of highways and main roadways (the 150 mile radius – range still applies). For example there are regions within some of the 300 mile zones where there essentially are no roads, or the roads are very minor. Since most of the horde will mistakenly take to the highways, this will create some number of safer areas within some of the zones that are shown. The other exception is that there are some geographical obstacles and deterrence within some of these zones which most of the horde will not attempt to overcome, such as mountainous terrain.
The purpose of the map is to help identify your risk based on where you live and to help to identify ‘safer’ regions within the USA. I’ve included cities on the southern border of Canada which are populated greater than 100,000 since this may affect some of the northern states of the U.S.
The most surprising and interesting data to come out of this map for me was this… take a look at West Virginia, which is tucked right in the middle of the eastern U.S. and all of its population centers. Notice the good size chunk towards the southern end of the state which is free from any of the 300 mile zones. Huh… Interesting.
The rest is fairly obvious.

Hello
I’m one of bruce beach / ark two ‘s librarians
you can confirm me w/ him or fred walter.
one real BIG suggestion I have is this ;
can you convert your survivial blog
into PDF files by topics ?
as you yourself have written, the internet
has a lifetime about 5 secs past a power
blackout. that leaves people with NO way
to read the excellent work you’ve been writing
– and a collection of PDF files would be a very good way to fill that gap in coverage
thank you very much for doing a very good job in your blogging and writing

Thank you for the kind words. In fact, as you suggest, I recommend to everyone to print and keep hard copies of important documentation and information that would contribute to safer survival after a collapse (electrical power collapse, internet down, worse…) rather than relying on the internet, saved bookmarks on your browser, etc…
Having PDF electronic files is a good first step, having this information directly saved on your computer. This is good as long as you have electric power.
Also, lately, there has been more and more talk from officials in the US government regarding taking over the internet under certain conditions, or having a “kill” switch for the internet, all as rationale to deal with potential cyber attacks such as the recent cyber attacks that we have been hearing about. Makes you wonder if this is a convenient excuse to gain more control over a free flowing conduit of information, something that the government doesn’t control yet.
In any event, at some point I may consider a PDF portal. Thanks for the suggestion.
