    Unless it breaks the water surface while still a hot gas bubble, an underwater nuclear explosion leaves no trace at the surface but hot, radioactive water rising from below. This is always the case with explosions deeper than about 2,000 ft (610 m). [6] About one second after such an explosion, the hot gas bubble collapses because:

  3. Gas explosion - Wikipedia

    A balloon filled with gaseous hydrogen exploding.. A gas explosion is the ignition of a mixture of air and flammable gas, typically from a gas leak. [1] In household accidents, the principal explosive gases are those used for heating or cooking purposes such as natural gas, methane, propane, butane.

  4. Mushroom cloud - Wikipedia

    en.wikipedia.org/wiki/Mushroom_cloud

    A detonation significantly below ground level or deep below the water (for instance, a nuclear depth charge) does not produce a mushroom cloud, as the explosion causes the vaporization of a huge amount of earth or water, creating a bubble which then collapses in on itself; in the case of a less deep underground explosion, this produces a ...

    Explosion of unserviceable ammunition and other military items The explosion of the Castle Bravo nuclear bomb. An explosion is a rapid expansion in volume of a given amount of matter associated with an extreme outward release of energy , usually with the generation of high temperatures and release of high-pressure gases .

  6. Implosion (mechanical process) - Wikipedia

    en.wikipedia.org/wiki/Implosion_(mechanical_process)

    In an implosion-type nuclear weapon design, a sphere of plutonium, uranium, or other fissile material is imploded by a spherical arrangement of explosive charges. This decreases the material's volume and thus increases its density by a factor of two to three, causing it to reach critical mass and create a nuclear explosion.

    The game Elite is widely considered to be the breakthrough game of the genre, [1] [2] [3] and as having successfully melded the "space trading" and flight sim genres. [4] Elite was highly influential upon later games of its type, although it did have some precursors. Games similar to Elite are sometimes called "Elite-clones". [5] [6] [7] [8]

    Littoral explosion at Waikupanaha ocean entry at the big island of Hawaii was caused by the lava entering the ocean. A steam explosion is an explosion caused by violent boiling or flashing of water or ice into steam, occurring when water or ice is either superheated, rapidly heated by fine hot debris produced within it, or heated by the interaction of molten metals (as in a fuel–coolant ...
