Hibakujumoku (Japanese: 被爆樹木; also called survivor tree or A-bombed tree in English) is a Japanese term for a tree that survived the atomic bombings of Hiroshima and Nagasaki in 1945. The term is from Japanese: 被爆, romanized: hibaku, lit. 'bombed, A-bombed, nuked' [1] and Japanese: 樹木, romanized: jumoku, lit. 'trees and shrubs'. [2]
The resulting explosion released the equivalent energy of 21 ± 2 kt (87.9 ± 8.4 TJ). [139] Big Stink spotted the explosion from 160 kilometers (100 mi) away, and flew over to observe. [209] The bomb destroyed the Roman Catholic Urakami Tenshudo Church. Bockscar flew on to Okinawa, arriving with only sufficient fuel for a single approach ...
Developed between 1956 and 1961 as the Soviet Union engaged in a nuclear arms race with the United States, the Tsar Bomba - the King of Bombs - was the largest hydrogen bomb ever and was claimed ...
The detonation produced a crater 1.9 km (6,200 ft) in diameter and 50 m (160 ft) deep where Elugelab had once been; [9] the blast and water waves from the explosion (some waves up to 6.1 m (20 ft) high) stripped the test islands clean of vegetation, as observed by a helicopter survey within 60 minutes after the test, by which time the mushroom ...
[55] [56] In January 2016, North Korea claimed to have successfully tested a hydrogen bomb, [57] although only a magnitude 5.1 seismic event was detected at the time of the test, [58] 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 ...

A transient condensation cloud, also called a Wilson cloud, is observable surrounding large explosions in humid air.
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.
