The Sploid blog has published a video of the largest nuclear explosions in history, beginning with Ivy Mike, the world's first hydrogen bomb that the US detonated in 1952.
It exploded on the island of Elugelab in the Marshall Islands in the Pacific Ocean with a force of 10.4 megatons of TNT; the detonation was detected 5,000 miles (8,000 km) away in California and vaporized the island.
For comparison, the atomic bomb dropped on Hiroshima yielded 15 kilotons of TNT, and the bomb that exploded over Nagasaki yielded 20 kilotons (0.2 megatons).
The US developed a hydrogen bomb after the Soviet Union carried out its first nuclear test in 1949. The Soviet's atomic bomb, called "First Lightning," yielded 22.4 kilotons of TNT and exploded at the Semipalatinsk Test Site, on the Steppe in northeast Kazakhstan.
