An explosion crater is a type of crater formed when material is ejected from the surface of the ground by an explosion at or immediately above or below the surface. Stylised cross-section of a crater formed by a below-ground explosion. A crater is formed by an explosion through the displacement and ejection of material from the ground.
The initial version was created in February 2012, with major upgrades in July 2013, [2] [3] [4] which enables users to model the explosion of nuclear weapons (contemporary, historical, or of any given arbitrary yield) on virtually any terrain and at virtually any altitude of their choice. [5]
Because the ADM was buried underground, the explosion blew tons of earth upwards, [15] creating a crater 300 ft (90 m) wide and 128 ft (39 m) deep. [16] The resulting mushroom cloud rose to a height of 12,000 ft (3,700 m) and subsequent radioactive fallout drifted in an easterly direction, travelling as far as 140 mi (225 km) from ground zero.
VEI and ejecta volume correlation. The volcanic explosivity index (VEI) is a scale used to measure the size of explosive volcanic eruptions.It was devised by Christopher G. Newhall of the United States Geological Survey and Stephen Self in 1982.
A subsidence crater is a hole or depression left on the surface of an area which has had an underground (usually nuclear) explosion. Many such craters are commonly present at bomb testing areas; one notable example is the Nevada Test Site , which was historically used for nuclear weapons testing over a period of 41 years.
The imagery shows a 200-foot-wide crater at the launch silo and damage around the launchpad, indicating there was a large explosion at some point during the test. Several fire trucks can be seen ...
Chinese scientists subsequently estimated that the second more powerful explosion involved the detonation of about 800 tonnes of ammonium nitrate, based on crater size and lethality radius (336 tons TNT equivalent, based on relative effectiveness factor of 0.42). [4] One month after the explosion, official reports listed 173 deaths and 797 ...
An aerial view taken from a helicopter shows a crater from an explosion after a likely WW2-era bomb exploded, on a taxiway at Miyazaki Airport in Miyazaki, southwestern Japan October 2, 2024, in ...
