喷火山口

Much of Yellowstone National Park is a giant collapsed volcano, or a caldera.

黄石国家公园的大部分地方是一座坍塌的大火山，或是一个喷火山口。

The park sits in the massive collapsed caldera of Copahue volcano.

A church on Thera overlooks the lava island of Nea Kameni, in the center of the caldera.

在希腊的Santorini 岛，宙斯神的教堂位于熔岩岛的沙丘，在喷火山口中心。

The volcano, which has been active for nearly a century, has a lake of molten lava at the center of its caldera.

Based on statistical results and the volcanic lithology and facies map, high cracks surface pore concentrates at diatreme subfacies and cryptoexploisve sub-facies of volcanic conduit facies, inner subfacies of extrusive facies, pyroclastic flow subfacies and base surge subfacies of explosive facies, lower subfacies of effusive facies which are close to the volcanic edifices center. Holes surface pore focus on upper and middle subfacies of effusive facies which locates in the edifice slope.

将物性结果结合平面岩性岩相图，确定出裂缝面孔率高的区域主要集中在火山机构中心附近的火山通道相火山颈亚相和隐爆角砾岩亚相、侵出相内带亚相、爆发相热碎屑流和热基浪亚相、喷溢相下部亚相；气孔面孔率高的区域集中在距离火山口较近的斜坡处，亚相主要为喷溢相上部、中部亚相。

Of them, we proposed the term of the Toyon volcanogroup in the first time. All the volcanoes can be subdivided into two types: central-eruption-typeand flood-basalt-type, building a series of volcanic mechanism, including calderas, volcanicnecks and cone sheets.

托云火山岩是由多个近于同时喷发的火山口的喷出物复杂堆积的产物，这些火山口可以划分成中心式火山和溢流玄武岩两种类型，它们共同组成了托云火山群。

Because spouts rock magma cooling and the contraction, the volcano crown caves in along with it, forms the size not to wait for, the shape to vary, the endophragm steep 10 craters, the crater diameter 50-500 meters, deep 401,145 meters, elevation 90,011,000 meters.

由于喷出的岩浆冷却和收缩，火山顶部随之塌落，形成大小不等、形状不一、内壁陡峭的10个火山口，火山口直径50-500米，深40一145米，海拔900一1000米。

The next day, four giant explosions occurred, the third of which blew away the northern two-thirds of the island and caused 120-foot tidal waves that killed 36,000 people on the nearby islands of Java and Sumatra.

喀拉喀托火山上四个火山口同时喷发。第三个火山口喷出的岩浆蔓延覆盖了小岛北部的三分之二的面积，引发了高达120英尺的潮汐，另外在小岛附近的爪哇和苏门达腊岛的36.000人也因此丧命。

Flashes of lightning add to the drama of an eruption as Tavurvur Volcano spews lava in the Rabaul Caldera in Papua New Guinea.

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
