The piezoelectric blast gauges were thrown off scale and no records were obtained. The excess-velocity blast-yield measurement (precise measurement of the velocity of sound at the site of the explosion and then comparing it with the velocity of the blast wave) [126] provided among the most accurate measurements of the blast pressure. Another ...
The atomic bomb explosion generated a windstorm several kilometers wide that carried ash, dust, and debris over the mountain ranges surrounding Nagasaki. Approximately 20 minutes after the bombing, a black rain with the consistency of mud or oil came down carrying radioactive material for one to two hours before turning clear. [227]
After the war, the Hiroshima Branch reopened. "The Human Shadow of Death" and the Atomic Bomb Dome quickly became landmarks for the bomb's destructive power and the loss of life. [19] [20] To preserve the shadow, in 1959 Sumitomo Bank built a fence surrounding the stone, and in 1967 the stone was covered with tempered glass to prevent its ...
For the first time in nearly 60 years, Russian energy corporation Rosatom has released video of the most powerful nuclear bomb ever to be detonated on Earth, reported IFL Science. The enthralling ...
Despite the lethal radiation and blast zone extending well past her position at Hiroshima, [55] Takakura survived the effects of a 16 kt atomic bomb at a distance of 300 metres (980 ft) from the hypocenter, with only minor injuries, due mainly to her position in the lobby of the Bank of Japan, a reinforced concrete building, at the time.
A watch melted during the Aug. 6, 1945, bombing of Hiroshima, Japan, has sold for more than $31,000 at auction. The watch is frozen in time at the moment of the detonation of an atomic bomb over ...
Weighing 14 pounds and responsible for 80,000 deaths, the heart of the "Fat Man" atomic bomb was detonated on August 9, 1945, over the Japanese city of Nagasaki. Related: Iconic photos from WWII:
At 11:02 A.M., August 9, 1945 an atomic bomb exploded 500 meters above this spot. The black stone monolith marks the hypocenter. The fierce blast wind, heat rays reaching several thousand degrees and deadly radiation generated by the explosion crushed, burned, and killed everything in sight and reduced this entire area to a barren field of rubble.
