<p>Due to Global Warming the future weather is not expected to be similar to the past. Earthquakes, hurricanes, tornadoes, and floods could occur anywhere on earth. We detail secure habitats for the hostile weather. Tornado has no effect on buildings with circular exteriors. A hurricane finds it extremely difficult to uproot a hemisphere or a hemi ellipsoid in which the radius of an upper floor is less than that of a lower floor. Floods do not affect a building with entry above ground when the flood height is less than the entry. A building with triangles formed by pillars and beams is more resistant to earthquake than without any triangle. Our buildings have above the floor entry; have circular exteriors; have triangles in the structural frame; and are hemisphere or hemi ellipsoid shaped with the radius of an upper floor being less than that of a lower floor.</p> |
