A mushroom cloud is a distinctive mushroom-shaped flammagenitus cloud of debris, smoke, and usually condensed water vapour resulting from a large explosion. The effect is most commonly associated with a nuclear explosion, but any sufficiently energetic detonation or deflagration will produce a similar effect.
Free-air gravity anomaly over the Chicxulub structure (coastline and state boundaries shown as black lines). The Chicxulub crater (pronunciation: [t͡ʃikʃuˈlub] ⓘ cheek-shoo-LOOB) is an impact crater buried underneath the Yucatán Peninsula in Mexico.
The second explosion was much larger and involved the detonation of about 800 tonnes of ammonium nitrate (approx. 256 tonnes TNT equivalent). [ 4 ] [ 5 ] Fires caused by the initial explosions continued to burn uncontrolled throughout the weekend, resulting in eight additional explosions on 15 August.
GIF was one of the first two image formats commonly used on Web sites, the other being the black-and-white XBM. [5] In September 1995 Netscape Navigator 2.0 added the ability for animated GIFs to loop. While GIF was developed by CompuServe, it used the Lempel–Ziv–Welch (LZW) lossless data compression algorithm patented by Unisys in 1985.

During the war, white phosphorus mortar bombs, shells, rockets, and grenades were used extensively by American , Commonwealth , and, to a lesser extent ...
Blast from a US Navy fuel–air explosive used against a decommissioned ship, USS McNulty, 1972 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.
The largest explosion had an estimated yield of 0.25 kiloton TNT equivalent (similar to a 1.0 kiloton nuclear explosion in free air). [2] USDOL concluded that the initiation mode of the fire was undetermined. It stated that smoking, sparking of electrical equipment, or frictionally ignited gas are among the probable igniting sources. [9]
