Iceland lies on the convergence of two tectonic plates and is one of the most volcanically active areas in the world .

冰岛位于两大地壳板块的交界处，是世界上火山活动最活跃的地区之一。

In alaska in the aleutian islands-it 's a volcanically active area-and there 's a lot of flight pathways that would cross where that ash would potentially drift .

阿留申群岛的阿拉斯加是火山活跃区--这里有很多航线经过，而火山灰也很可能飘到这。

In fact , since seismic shifts are so closely related to volcanic action , geologists listen in to the seismic movements around volcanically active regions to predict when earthquakes might spark volcanic eruptions .

其实，既然地球板块移动与火山活动关系如此密切，那么地质学家可以通过测听火山活动地区的地壳运动来预测什么时候地震引发火山喷发。

Roger phillips , a planetary scientist at the southwest research institute , called the result " as close as possible to a smoking gun " in the hunt for evidence that venus is volcanically active .

罗格菲尔普斯（rogerphillips），西南研究所（southwestresearchinstitute）的一名行星科学家，将这个结果称为寻找金星火山是活火山的证据的过程中“无限接近的确凿证据”。

Knowing that venus is volcanically active could shed light on the mysterious geological history of earth 's sister planet , which does not have plate tectonics , meaning the planet 's surface does not evolve through a process of rigid plates slowly shifting across the underlying mantle .

知晓金星上的火山是活跃的可能能够为了解金星神秘的地质历史提供线索，金星没有板块构造，这意味着金星的地表并非从一个刚性板块在地幔底层缓慢移动的过程中演化而来。
