The Genbaku Dome in Hiroshima's Peace Park marks the World's first use of nuclear bomb as a weapon. The 6 August 1945 nuclear explosion was almost directly above the building (the hypocenter was 150 meters / 490 feet away), and it was the closest structure to withstand the explosion. The building has been preserved in the same state as immediately after the bombing, and now serves as the reminder of nuclear devastation and as a symbol of hope for world peace and elimination of all nuclear weapons. The three storey 1915 exhibition hall had been solidly built in ferro-concrete and brick. It was incinerated and its dome exploded, but surprisingly the steel frame survived. Today it is known as Hiroshima's Atomic Bomb Dome. (end quote) "but surprisingly the steel frame survived" And again ... "but surprisingly the steel frame survived" Let's recap. An atomic bomb leaves a steel framed building intact at Ground Zero, Hiroshima, but 56 years later, a kerosene fire melts and softens the steel in three seperate steel framed skyscrapers. The heat from the burning kerosene (restricted to a few floors) was so intense that it softened the steel framed structures and they collapsed, at free fall speeds, into their own basements. Why didn't the Hiroshima steel framed building soften and collapse? Does kerosene burn hotter than the epicentre of an atomic bomb? Why was the Japanese steel framed building capable of surviving the heart of a nuclear explosion, but WTC1, WTC2 and WTC7 all ...
