The blast caused earthquakes, tsunamis and pyroclastic flows that decimated the land and took tens of thousands of Indonesian lives.

火山爆发引发了地震、海啸和火山碎屑流，摧毁了这片土地，夺走了数万印度尼西亚人的生命。

In addition to lava, volcanoes may erupt with searing hot gas formed in the mantle, in a phenomenon called pyroclastic flow.

除了熔岩，火山喷发时还伴有在地幔中形成的灼热气体，这现象叫做火山碎屑流。

Blazing pyroclastic flows, racing down mountainsides, would annihilate  everything they touch.

炽热的火山碎屑流，从山坡上冲下，将湮灭它们所接触到的一切。

Even worse is the damage caused by pyroclastic flows.

更糟的是火山碎屑流造成的破坏。

Hot ash and noxious gas billow out in a wave known as a pyroclastic surge.

炽热的火山灰和有毒气体以一为火山碎屑潮的波浪形式涌出。

Pyroclastic surges are super-heated winds of ash, rock, and volcanic gases.

火山碎屑潮是火山灰、岩石和火山气体的过热风。

People were  either buried alive in the ash or were instantly killed by the pyroclastic surges.

人们要么活埋在火山灰中，要么立即火山碎屑浪潮杀死。

About 92,000 people died due to pyroclastic flows, a tsunami triggered by the eruption, and famines from the weather changes.

大约 92,000 人死于火山碎屑流、火山爆发引发的海啸以及天气变化造成的饥荒。

Another pyroclastic surge rushes across the valley, crashes into Pompei, and sheers off the upper levels of the town's buildings.

另一股火山碎屑涌动冲过山谷，冲入庞贝，并从该镇建筑物的上层滑落。

Pompeii and nearby Herculaneum were utterly annihilated by a wave of  pyroclastic lava flow and buried beneath immense piles of ash.

庞贝古城和附近的赫库兰尼姆一股火山碎屑熔岩流彻底摧毁，并埋在巨大的火山灰下。

These include the ash, which  historians believe fell at a rate of four to six inches an hour, and the pyroclastic surges.

其中包括火山灰，历史学家认为火山灰以每小时 4 到 6 英寸的速度下落，以及火山碎屑的涌动。

There are no alpine peaks or grinding glaciers, no great deposits of oil or precious metals, not a hint of a pyroclastic flow.

没有高山山峰或磨冰川, 没有大量的石油或贵金属矿藏, 没有一丝火山碎屑流的痕迹。

You would probably need to run away as fast and as far as possible to get away from the hot spewing lava and the deadly pyroclastic cloud.

你可能需要尽可能快的跑开，远离喷出的炽热熔岩和致命的火山碎屑云。

And one thing that's a threat to them are pyroclastic flows, when a mix of lava blocks, ash and volcanic gas rush down the slopes of a volcano.

对它们构成威胁的是火山碎屑流——即熔岩块、火山灰和火山气体的混合物冲下火山斜坡（的过程）。

These eruptions spew more than 1,000 cubic kilometers of volcanic ash, pumice, and  other pyroclastic materials into the atmosphere, usually with catastrophic consequences for  life and Earth's climate.

这些火山喷发向大气中喷射了超过 1,000 立方公里的火山灰、浮石和其他火山碎屑物质，通常会给生命和地球气候带来灾难性后果。

At least 14 people were killed in the eruption, nine are still missing, dozens were injured and officials say the mountain is still dangerous because it's produced at least two pyroclastic flows.

至少14人在火山爆发中死亡，9人仍下落不明，数十人受伤，官员这座山仍然很危险，因为它产生了至少两股火山碎屑流。
