This dome home, a patented-steel reinforced concrete structure, properly called a thin-shell dome, was designed by structural engineers to withstand almost any natural or man-made disaster you can name. These buildings have withstood tornadoes, hurricanes, and earthquakes – some measuring over 7.0 on the Richter scale – and in every case they have come away with no structural damage at all. Not only that, but a bomb shelter built with this exact type of construction, was tested at a U. S. military facility against a simulated nuclear explosion in the multi-kiloton range and was completely undamaged by the test. Amazingly, a burning candle inside the shelter was not even extinguished by the blast. Every other shelter tested in this trial sustained some measure of damage.
