"The place deemed the safest in America by the government and military is Colorado. Specifically, Denver. Interestingly enough, there is a nuclear power plant in the vicinity, but only one, and Denver is known as a disaster-free area and by far the safest to survive a global cataclysm. There’s no oceans nearby and the “Mile High City” is exceedingly safe, even from a 1,000ft high tsunami roaring in from the Pacific. There are no known earthquake faults in the area, no nearby volcanic activity and the city is the furthest inland through very difficult terrain should a direct military attack/invasion be carried out on the U.S."
