Eniwetok Atoll in the South Pacific after the Mike shot; the detonation of the first thermonuclear (or hydrogen) bomb on October 31st 1952. Elugelab, the island upon which the test occurred, was wholly obliterated (it had been located just beyond the three linked islands). The blast was equivalent to 10.2 megatonnes of high explosive & created a mushroom cloud 35km high. The device consisted of a core of hydrogenous solid material flanked by twin fission (or atomic) bombs acting as triggers. The latter were required to elevate the hydrogen to its ignition temperature allowing the nuclear fusion reaction to take place.
