The fireball created by the explosion had a maximum radius of 2.9 to 3.3 km (1.8 to 2.1 mi). [20] [21] [22] The maximum radius was reached several seconds after the detonation, during which the hot fireball lifted up due to buoyancy. While still relatively close to the ground, the fireball had yet to reach its maximum dimensions and was thus ...
The bomb was detonated on November 1, 1952, on Elugelab Island yielding 10.4 megatons, almost 500 times the yield of the bomb dropped on Nagasaki, resulting in the total vaporization of the island. Eight megatons of the yield were from fast fission of the uranium tamper, creating massive amounts of radioactive fallout.
The fireball created by Ivy Mike had a maximum diameter of 5.8 to 6.56 km (3 + 5 ⁄ 8 to 4 + 1 ⁄ 8 mi). [ 5 ] [ 6 ] [ 7 ] This maximum is reached a number of seconds after the detonation and during this time the hot fireball invariably rises due to buoyancy .
The explosions constituted what was then the loudest human-made sound in history, and could be heard in London. The largest single charge was the Lochnagar mine south of La Boisselle with 60,000 lb (27 t) of ammonal explosive. The mine created a crater 300 ft (90 m) across and 90 ft (30 m) deep, with a rim 15 ft (5 m) high.
The disaster was the largest man-made explosion of the time and caused extensive damage to Richmond, Dartmouth, and the Miꞌkmaq neighborhood of Tufts Cove. 4-6 December 1918 United States: Sayreville, New Jersey ~100 100+ T.

Developed between 1956 and 1961 as the Soviet Union engaged in a nuclear arms race with the United States, the Tsar Bomba - the King of Bombs - was the largest hydrogen bomb ever and was claimed ...

At Kwajalein, 1,400 [nautical] miles [2,600 km; 1,600 mi] to the west, a dense overcast extended the length of the eastern horizon to a height of 5 or 8 degrees. At 0900 GMT a brilliant white flash burned through the clouds rapidly changing to an expanding green ball of irradiance extending into the clear sky above the overcast.
