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

爆发引发地震、海啸和屑流，摧毁这片土地，夺万印度尼西亚人的生命。

Even worse is the damage caused by pyroclastic flows.

更糟糕的是屑流造成的破坏。

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

屑潮是灰、岩石和气体的过热风。

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

炽热的屑流，从坡上冲下，将湮灭它们所接触到的一切。

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

除熔岩，喷发时还伴有在地幔中形成的灼热气体，这种现象叫做屑流。

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

炽热的灰和有毒气体以一种被称为屑潮的波浪形式涌出。

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

人们要么被活埋在灰中，要么立即被屑浪潮杀死。

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 人死于屑流、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.

另一股屑涌动冲过谷，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被一股屑熔岩流彻底摧毁，并被埋在巨大的灰下。

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

其中包括灰，历史学家认为灰以每小时 4 到 6 英寸的速度下落，以及屑的涌动。

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

没有高峰或磨冰川, 没有大量的石油或贵金属矿藏, 没有一丝屑流的痕迹。

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屑流——即熔岩块、灰和气体的混合物冲下斜坡（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.

这些喷发向大气中喷射超过 1,000 立方公里的灰、浮石和其他屑物质，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人在爆发中死亡，9人仍下落不明，十人受伤，官员称这座仍然很危险，因为它产生至少两股屑流。
