The Nagasaki Atomic Bomb exploded on August 9, 1945, 11:02 am, about 500 meters above 171 Matsuyama-cho, Nagasaki City. This was an aerial photograph of the situation damaged immediately after the Nagasaki Atomic Bomb. The hypocenter "Ground Zero" was about 2.5 km upstream of the Uragami River from the upper left corner of the aerial photograph. At field-battle order No.17, the original aiming point 114016 was on the Nigiwai bridge on the way of Nakashima River. For that purpose, this had been an aerial photograph focusing mainly on the Nagasaki bay area and the aiming point of Nakasaki Atomic Bomb. The periphery of the hypocenter "Ground Zero" at the upper left corner was completely ashamed in a moment. Nagasaki city was surrounded by mountains in the east and west, while the disaster area completely destroyed the houses reached about 2.5 km south east to Nagasaki Port, extended more than about 2 km of Hiroshima Atomic Bomb. The damage suffered into the semi-rupture ranged from the hypocenter to about 4 km southward.
