subsidence crater造句

• If it does, a subsidence crater is created.
• More mysterious are photographs of a landscape dotted with subsidence craters from underground testing.
• Hundreds of subsidence craters dot the desert floor.
• Subsidence craters are created as the roof of the cavity caused by the explosion collapses.
• If this chimney reaches the surface, a bowl-shaped subsidence crater may form.
• Note subsidence craters at center, apparently from the attempts to plug the leaking well.
• This causes the surface to depress into a sink ( which subsidence craters are sometimes called, see more : sink hole ).
• A " surface collapse feature ", also known as a subsidence crater, was formed by material collapsing into the cavity formed by the explosion.
• The Yucca Flat section of the NTS is covered with subsidence craters resulting from the collapse of terrain over radioactive underground caverns created by nuclear explosions ( see photo ).
• A subsidence crater in nearby Area 5 is home to a number of storage containers holding contaminated scrap metal and debris, and is subject to periodic monitoring of radioactivity levels.
• A caldera, which is a large subsidence crater, can form in a stratovolcano, if the magma chamber is partially or wholly emptied by large explosive eruptions; the summit cone no longer supports itself and thus collapses in on itself afterwards.
• Detonations significantly below ground level or deep below the water ( for instance, nuclear depth charges ) also do not produce mushroom clouds, as the explosion causes the vaporization of a huge amount of earth and water in these instances, creating a bubble which then collapses in on itself; in the case of a less deep underground explosion, this produces a subsidence crater.
