An underwater explosion (also known as an UNDEX) is a chemical or nuclear explosion that occurs under the surface of a body of water. While useful in anti-ship and submarine warfare, underwater bombs are not as effective against coastal facilities.
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 ...
The explosion, probably caused by a change in the plumbing under the hot spring, launched a plume of water and rock fragments 400–600 feet (120–180 m) into the air. [12] Although there were no injuries, the explosion forced the closure of Biscuit Basin for the rest of the 2024 season.
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. Explosions may also be ...
Dry ice bombs can explode within seconds due to the rapid sublimation of dry ice, injuring the handler. The abrupt release of high-pressure gas creates a loud noise, which can cause hearing damage even at substantial distances. Fragments thrown at high speeds can cut or puncture.
A thermobaric bomb is a type of explosive that utilizes oxygen from the surrounding air to generate an intense, high-temperature explosion, and in practice the blast wave typically produced by such a weapon is of a significantly longer duration than that produced by a conventional condensed explosive. The fuel-air bomb is one of the best-known ...
The explosion creates a bubble in the water, and due to the pressure difference, the bubble will collapse from the bottom. The bubble is buoyant, and so it rises towards the surface. If the bubble reaches the surface as it collapses, it can create a pillar of water that can go over a hundred meters into the air (a "columnar plume").
A thermobaric weapon, also called an aerosol bomb, or a vacuum bomb, [1] is a type of explosive munition that works by dispersing an aerosol cloud of gas, liquid or powdered explosive. [ 2 ] [ 3 ] The fuel is usually a single compound, rather than a mixture of multiple substances. [ 4 ]
