A nuclear explosion is an explosion that occurs as a result of the rapid release of energy from a high-speed nuclear reaction.The driving reaction may be nuclear fission or nuclear fusion or a multi-stage cascading combination of the two, though to date all fusion-based weapons have used a fission device to initiate fusion, and a pure fusion weapon remains a hypothetical device.
Much of the destruction caused by a nuclear explosion is from blast effects. Most buildings, except reinforced or blast-resistant structures, will suffer moderate damage when subjected to overpressures of only 35.5 kilopascals (kPa) (5.15 pounds-force per square inch or 0.35 atm).
The explosion of Tsar Bomba, according to the classification of nuclear explosions, was an ultra-high-power low-air nuclear explosion. [citation needed] The mushroom cloud of Tsar Bomba seen from a distance of 161 km (100 mi). The crown of the cloud is 65 km (40 mi) high at the time of the picture.

High-altitude nuclear explosions are the result of nuclear weapons testing within the upper layers of the Earth's atmosphere and in outer space. Several such tests were performed at high altitudes by the United States and the Soviet Union between 1958 and 1962. The Partial Test Ban Treaty was passed in October 1963, ending atmospheric and ...
Fukushima nuclear accident. Coordinates: 37°25′17″N 141°1′57″E. Fukushima nuclear accident. Part of the 2011 TÅhoku earthquake and tsunami. The four damaged reactor buildings (from left: Units 4, 3, 2, and 1) on 16 March 2011. Hydrogen-air explosions in Units 1, 3, and 4 caused structural damage. [1] Date.
A nuclear weapon[a] is an explosive device that derives its destructive force from nuclear reactions, either fission (fission bomb) or a combination of fission and fusion reactions (thermonuclear bomb), producing a nuclear explosion. Both bomb types release large quantities of energy from relatively small amounts of matter.
Rope trick effect. Nuclear explosion milliseconds after detonation. From the Operation Teapot test series in Nevada, 1955, showing fireball and rope trick effects. Rope trick is the term given by American nuclear physicist John Malik to the curious lines and spikes which emanate from the fireball of nuclear explosions under certain conditions ...
A nuclear electromagnetic pulse (nuclear EMP or NEMP) is a burst of electromagnetic radiation created by a nuclear explosion. The resulting rapidly varying electric and magnetic fields may couple with electrical and electronic systems to produce damaging current and voltage surges. The specific characteristics of a particular nuclear EMP event ...
