像宽干谷这样爆裂的火山口形成于蒸汽喷发的过程中，在那里，上升的岩浆与地表下的水接触形成了蒸汽喷发。
Volcanic explosion craters such as Dallol form during phreatic eruptions—where rising magma comes into contact with water beneath the surface of the Earth, causing a steam explosion.
这座单体火山拥有几乎是世界上最大的完整火山喷口，这个直径约为6.5公里（4英里）的锅型火山口，是当熔岩从火山内腔流过时，上部的岩浆岩坍塌而形成的。

Three crater lakes are located on the eastern summit of Keli Mutu.
这次火山喷发使山体产生了一个500米（2000英尺）的裂缝并导致了数个熔岩喷泉，它们在火山口周围形成了多个由泡沫填充岩（矿渣）组成的小山丘。
The eruption opened a 500-meter (2,000-foot) fissure, and also produced lava fountains that built several hills of bubble-filled lava rocks (scoria) along the vent.
火山熔岩从火山口的北边流淌下来，形成漩涡状的暗黑色岩体(图片已旋转，右边是北方，)。
Forming a paisley pattern, the dark volcanic rocks north of SP Crater result from lava flows. (This image has been rotated and north is at right.)
山顶有小圆形火山口，直径大约1千米，周围是80到300米高的墙（喷发岩形成的）。

When the enormous magma chamber at Santorini finally collapsed to form the existing caldera, enormous tsunamis (tidal waves) spread outward in all directions.
它溢过火山口的边沿，形成200英尺宽的一道沉重的熔岩流，缓缓地流动着穿过谷底，任何不能从它经过的地方逃离的东西必死无疑。
It came over the edge in a heavy stream, 200 feet wide, and travelled slowly across the valley, bringing certain death to everything that could not move from its path.
该超单元的形成与幔源基性岩浆上侵及同源岩浆分异产生的中偏基性—中性岩浆多次侵入有关，属热气球式膨胀与火山口塌陷复合就位机制。
Its formation was related to the intrusion of basic magma(mantle source)to multi-time intrusions of basicly medium to medium magma which differentiated from the same magma. The co…
