[56] [57] In January 2016, North Korea claimed to have successfully tested a hydrogen bomb, [58] although only a magnitude 5.1 seismic event was detected at the time of the test, [59] a similar magnitude to the 2013 test of a 6–9 kt (25–38 TJ) atomic bomb. These seismic recordings cast doubt upon North Korea's claim that a hydrogen bomb was ...
The medical effects of the atomic bomb upon humans can be put into the four categories below, with the effects of larger thermonuclear weapons producing blast and thermal effects so large that there would be a negligible number of survivors close enough to the center of the blast who would experience prompt/acute radiation effects, which were observed after the 16 kiloton yield Hiroshima bomb ...
Energy from a nuclear explosion is initially released in several forms of penetrating radiation. When there is surrounding material such as air, rock, or water, this radiation interacts with and rapidly heats the material to an equilibrium temperature (i.e. so that the matter is at the same temperature as the fuel powering the explosion).
The hydrogen bomb, which carried the force of 50 million tons of conventional explosives, was detonated in a test in October 1961, 4,000 meters over the remote Novaya Zemlya archipelago above the ...
Beginning with the Teller–Ulam breakthrough in March 1951, there was steady progress made on the issues involved in a thermonuclear explosion and there were additional resources devoted to staging, and political pressure towards seeing, an actual test of a hydrogen bomb. [6]: 137–139 A date within 1952 seemed feasible.
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. [65] For comparison, the largest weapon ever produced by the US, the now-decommissioned B41 , had a predicted maximum yield of 25 Mt (100 PJ).

The "human shadow" at the entrance of the Sumitomo Bank was approximately 260 metres (850 ft) from the hypocenter of the atomic bomb explosion at Hiroshima. It is thought that the person had been sitting on the stone step waiting for the bank to open when the heat from the bomb burned the surrounding stone white and left the person's shadow ...
