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。
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.
