A 16-inch (41 cm) natural gas pipeline ruptured under the stored ammonium perchlorate and added fuel to the later, larger explosions. There were seven detonations in total, the largest being the last. Two people were killed and hundreds injured. The largest explosion was estimated to be equivalent to 0.25 kilotons of TNT (1.0 TJ).
The Halifax Explosion was one of the largest artificial non-nuclear explosions. An extensive comparison of 130 major explosions by Halifax historian Jay White in 1994 concluded that it "remains unchallenged in overall magnitude as long as five criteria are considered together: number of casualties, force of blast, radius of devastation ...
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. A. Gillespie Company Shell Loading Plant explosion – Munitions explosion at an ammunition plant in New Jersey
The Tsar Bomba is the single most physically powerful device ever deployed on Earth, the most powerful nuclear bomb tested and the largest human-made explosion in history. [64] For comparison, the largest weapon ever produced by the US, the now-decommissioned B41 , had a predicted maximum yield of 25 Mt (100 PJ).
While hundreds of detonations were spread over three days, the totality of the event ranked as one of the largest man-made non-nuclear explosions in history. Some of the strongest individual blasts, from exploding storehouses or railcars of ammunition, broke windows as far away as Manhattan and Asbury Park , more than 20 miles (32 km) distant.
The Soviet Union detonated a 50-megaton yield hydrogen bomb known as Tsar Bomba over Novaya Zemlya, in the largest man-made explosion ever. Too large to be fit inside even the largest available warplane, [118] the weapon was suspended from a Tupolev Tu-95 piloted by A.E. Durnovtsev, a Hero of the Soviet Union. [119]
[2] [3] [4] The explosion was the worst peacetime military accident ever recorded in Cyprus, with a yield of approximately 481 tons TNT equivalent, as determined by the official investigation into the accident. [5] It was the largest artificial non-nuclear explosion of the 21st century until the 2020 Beirut explosions.
The test was held at the Suffield Experimental Station in Alberta and was the largest ever man-made, non-accidental explosion in Canada. The test was also the first of its kind using a stacked TNT block hemisphere of such magnitude, a method repeated in six subsequent tests such as Operation Sailor Hat and Prairie Flat .
