this rock type originates in the magma chambers that underlie volcanoes 这种岩石源自火山底下的岩浆库。
in caldera, thrusting jets of air rise through fine sand, mimicking the development and collapse of a volcanic magma chamber 的上升气流穿透细沙层喷射而出,模拟岩浆室在火山内的形成与塌陷。
as the land above the magma chamber collapses, immense gray clouds called pyroclastic flows burst out horizontally all around the caldera 当岩浆库上方的陆地崩陷,称为火山碎屑流的巨大灰色云雾,会突然由火山臼的周围向外水平散开。
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 这样的发现表示新一波的火山作用已经开始,而重新填满的岩浆库,更有可能造成灾难性的爆发。
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岩浆房最后倒塌,形成了现有的喷火山口,巨大的海啸(潮汐波)向各个方面向外伸展。
