A volcanic bomb or lava bomb is a mass of partially molten rock larger than 64 mm (2.5 inches) in diameter, formed when a volcano ejects viscous fragments of lava during an eruption. Because volcanic bombs cool after they leave the volcano, they are extrusive igneous rocks. Volcanic bombs can be thrown many kilometres from an erupting vent, and ...
Taking this one stage further, the clue word can hint at the word or words to be abbreviated rather than giving the word itself. For example: "About" for C or CA (for "circa"), or RE. "Say" for EG, used to mean "for example". More obscure clue words of this variety include: "Model" for T, referring to the Model T.
The individual rock fragments are known as pyroclasts. Pyroclastic rocks are a type of volcaniclastic deposit, which are deposits made predominantly of volcanic particles. [ 1 ] [ 2 ] 'Phreatic' pyroclastic deposits are a variety of pyroclastic rock that forms from volcanic steam explosions and they are entirely made of accidental clasts.
The Mills bomb was inspired by an earlier design by Belgian captain Leon Roland, who later engaged in a patent lawsuit. [2] Col. Arthur Morrow, a New Zealand Wars officer, also believed aspects of his patent were incorporated into the Mills Bomb. [3] The Mills bomb was adopted by the British Army as its standard hand grenade in 1915 as the No ...
Diagram of S-mine in the delivery of steel ball fragments. Fragmentation is the process by which the casing, shot, or other components of an anti-personnel weapon, bomb, barrel bomb, land mine, IED, artillery, mortar, tank gun, autocannon shell, rocket, missile, grenade, etc. are dispersed and/or shattered by the detonation of the explosive filler.
Dazed survivors immediately feared that the explosion was the result of a bomb dropped from a German plane. [84] Troops at gun batteries and barracks immediately turned out in case the city was under attack, but within an hour switched from defence to rescue roles as the cause and location of the explosion were determined.
The original explosion will send out fragments that travel very fast. Debris and sometimes even people can get swept up into a blast wave, causing more injuries such as penetrating wounds, impalement and broken bones. The blast wind is the area of low pressure that causes debris and fragments to rush back towards the original explosions.
Fragments of plastic consistent with the material used on a Bombeat and pieces of loudspeaker mesh, were found embedded in other clothing which appeared to have been inside the bomb suitcase: a white, Abanderado-brand T-shirt; cream-coloured pyjamas; a fragment of a knitted, brown, woollen cardigan with the label "Puccini design"; a herringbone ...
