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。
Merapi seems unlikely to explode on anything like this scale, but it has brought the risk of pyroclastic flows.
因此测量火山灰流的电荷量能够帮助科学家们更好的对火山灰的行动路线以及持续时间做出预判。
Measuring a plume's charges could therefore help scientists better estimate where the ash will go and how long it will stay aloft.
由于担心漂浮的火山灰可能阻塞飞机引擎,横贯欧洲大陆的火山灰流让途径欧洲飞往各地的航线被纷纷滞留。
The plume traveled to continental Europe, grounding flights around the world for days, due to fears of ash clogging plane engines. (Find out more about the risks volcanic ash poses to airplanes.)

使用现存的仪器就可以很简单的探测到电荷,因此一股携带电荷的火山灰流很容易进行追踪,即使火山灰流在可见范围内已经大面积扩散。
Electric charges are fairly easy to observe with existing instruments, so a charged plume should be easier to track, even after the visible plume has largely dispersed.
有时,动物和植物被浸泡在焦油或流沙中,被困在冰或熔岩流中,或被迅速落下的火山灰吞没后被保存下来。
On occasion, animals and plants have been preserved after becoming immersed in tar or quicksand, trapped in ice or lava flows, or engulfed by rapid falls of volcanic ash.
这个层状火山是由稠密的熔岩流以及火山灰和岩石碎片等喷发物所形成的连续层堆积而成的锥形火山,它位于一个更老的层状火山之上。
The current stratovolcano-a cone-shaped volcano built from successive layers of thick lava flows and eruption products like ash and rock fragments-is built on top of an older stratovolcano.
高达750摄氏度的火山熔岩伴随雷鸣般的咆哮声从山顶倾流而下,山口火舌吐出的火山灰高达四公里。
Searing 750-degree (Celsius) gas flowed down the mountainside in a thunderous roar, and deadly plumes spewed ash four kilometers above the crater.
杀伤机制:火山灰、火山碎屑流。
然而带电火山灰是在厚重的火山羽流中间被发现的,而不是在边缘。
But the electric volcanic ash was found in the middle of the thick plume, not on its edges.
除了熔岩流,埃特纳也几乎稳定、有节奏地喷发蒸汽、火山灰和熔融的岩石。
Besides lava flows, etna produces an almost constant, rhythmic discharge of steam, ash and molten rock.
