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 ...
The hydrogen bomb, which carried the force of 50 million tons of conventional explosives, was detonated in a test in October 1961. Russia releases secret footage of 1961 'Tsar Bomba' hydrogen ...
In the initial microseconds after the explosion, a fireball is formed around the bomb by the massive numbers of thermal x-rays released by the explosion process. These x-rays cannot travel very far in standard atmosphere before reacting with molecules in the air , so the result is a fireball that rapidly forms within about 10 metres (33 ft) in ...
A 21-kiloton underwater nuclear weapon test, the Baker shot of Operation Crossroads, showing a Wilson cloud Mushroom cloud with multiple condensation rings from the Castle Union 6.9 Mt hydrogen bomb test. A transient condensation cloud, also called a Wilson cloud, is observable surrounding large explosions in humid air.
The Mark 16 nuclear bomb was a large American thermonuclear bomb (hydrogen bomb), based on the design of the Ivy Mike, the first thermonuclear device ever test fired.The Mark 16 is more properly designated TX-16/EC-16 as it only existed in Experimental/Emergency Capability (EC) versions.
[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 ...
I scanned the trees and saw that a maple tree had "exploded". The explosion caused a big crack in the tree about three feet high. When a winter wind stirs the frozen trees, they sometimes appear to burst vertically. When it was 40 degrees below zero at night, I lay awake and listened to the trees explode. That's a true wilderness thermometer!
