Nagasaki nuclear bomb, 9 August 1945
Nagasaki nuclear bomb detonation. Video footage of the detonation of the nuclear bomb (Fat Man) dropped on Nagasaki, Japan, on 9th August 1945. The bomb was delivered by a US bomber during World War II. The atomic explosion, equivalent to 21,000 tons of TNT, generated a dense column of smoke and a mushroom cloud that rose over 18 kilometres into the air. This was the second atomic bomb used in warfare, following the atomic bomb over Hiroshima three days earlier. Over 220,000 people died in both cities, and thousands were injured. Japan surrendered a few days later.
