But the electric volcanic ash was found in the middle of the thick plume, not on its edges.

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。

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.

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。
