This rock type originates in the magma chambers that underlie volcanoes 這種巖石源自火山底下的巖漿庫(kù)。
In caldera , thrusting jets of air rise through fine sand , mimicking the development and collapse of a volcanic magma chamber 的上升氣流穿透細(xì)沙層噴射而出,模擬巖漿室在火山內(nèi)的形成與塌陷。
As the land above the magma chamber collapses , immense gray clouds called pyroclastic flows burst out horizontally all around the caldera 當(dāng)巖漿庫(kù)上方的陸地崩陷,稱為火山碎屑流的巨大灰色云霧,會(huì)突然由火山臼的周圍向外水平散開。
Such findings would imply that a new cycle of volcanism had commenced ? and that the newly engorged magma chamber had more potential to explode catastrophically 這樣的發(fā)現(xiàn)表示新一波的火山作用已經(jīng)開始,而重新填滿的巖漿庫(kù),更有可能造成災(zāi)難性的爆發(fā)。
When the enormous magma chamber at santorini finally collapsed to form the existing caldera , enormous tsunamis ( tidal waves ) spread outward in all directions 圣多里尼火山的巨大巖漿房最后倒塌,形成了現(xiàn)有的噴火山口,巨大的海嘯(潮汐波)向各個(gè)方面向外伸展。
A magma chamber is a large underground pool of liquid rock found beneath the surface of the Earth. The molten rock in such a chamber is under great pressure, and given enough time, that pressure can gradually fracture the rock around it creating outlets for the magma.
