Don't forget how close you live to a nuclear power plant and also your relative location to minute -man missle sites and their location to geographic faults. (In addition missle sites are primary targets in the event of war.) Also, your relative location to international trade winds in case of nulear war in the middle east or volcanic erruptions. I guess this is not really classified as natural disasters but is part of the picture. I hope this makes sense. I can't write very well.

Thanks!
