Killing mechanism: ash, pyroclastic flows.

杀伤机制：火山灰、火山碎屑流。

Pyroclastic flows are some of the most fearsome hazards posed by erupting volcanoes.

火山碎屑流是由火山喷发而引起的最可怕自然灾害。

Merapi seems unlikely to explode on anything like this scale, but it has brought the risk of pyroclastic flows.

默拉皮火山似乎不可能爆发到这种程度，但是它能够带来危险性极强的火山灰流。

More recently, pyroclastic flows from Mount Merapi in Indonesia caused most of the casualties during the volcano's 2010 eruption.

2010年，印度尼西亚的默拉皮(Mount Merapi)火山爆发，火山碎屑流造成了大量的人员伤亡。

Lava flows, pyroclastic flows, lahars and volcanic tsunamis are the major hazards that threaten the life and property of the people.

其中对人类生命财产构成严重威胁的火山灾害有熔岩流、火山碎屑流、火山泥流和火山海啸。
