Determining the power of explosions is difficult, but this was probably the largest planned explosion in history until the 1945 Trinity atomic weapon test, and the largest non-nuclear planned explosion until the 1947 British Heligoland detonation (below). The Messines mines detonation killed more people than any other non-nuclear deliberate ...
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 ...
An independent estimate by the International Monitoring System of the Comprehensive Nuclear-Test-Ban Treaty Organization based on infrasonic data obtained an explosive yield equivalent to 0.5–1.1 kt of TNT, [72] making it the sixth-largest accidental artificial non-nuclear explosion in human history.
The joint explosion ranks among the largest non-nuclear explosions, surpassing the mines on the first day of the Somme fired 11 months before. The sound of the blast was considered the loudest man-made noise in history.
The explosion used 7400 tons (6700 metric tons) of surplus World War II ammunition, which was placed in various locations around the island and detonated at 1 p.m. on 18 April 1947 by the Royal Navy. The energy released was 1.3×10 13 J, or about 3.2 kilotons of TNT equivalent [ 1 ] making it the largest artificial non-nuclear explosion at that ...
It may still include entries for which the cause is unclear or still under investigation. For a list based on power or death toll see largest artificial non-nuclear explosions or the explosions section of list of accidents and disasters by death toll. This list also contains notable explosions that would not qualify for the articles mentioned ...
The single-most important thing to remember if a nuclear bomb is supposed to explode, he says, is to shelter in place. "There were survivors in Hiroshima within 300 meters of the epicenter ...
The joint explosion of these mines ranks among the largest artificial non-nuclear explosions. Eight big and eleven tiny charges were buried deep in the chalky earth to make up the 19 mines. They were "overcharged" to throw up high lips for screening and to give advantage to the attackers if they were able to capture the resulting craters. [1]
