Volcano warning: 'Something is brewing under Europe' Geologists make incredible discovery

火山警告：“欧洲地下正在酝酿着什么”地质学家有了令人难以置信的发现

A VOLCANIC mantle plume under northwest Europe is showing potential signs of activity as geologists suspect "something is brewing" deep underground.

欧洲西北部的火山地幔柱显示出潜在的活动迹象，地质学家怀疑地下深处“正在酝酿着什么”。

Scientists from the US have found new evidence of volcanism in Europe, linked to an ancient mantle plume extending up to 248 miles (400km) underground. GPS monitoring data crowd-sourced from European antennas shows slight movements in the Earth's surface - a potential sign of a rising mantle plume. Mantle plumes are upwellings of scorching hot rock within the planet's mantle that can feed active volcanism.

美国科学家发现了欧洲火山活动的新证据，火山活动与延伸至地下248英里(400公里)的古老地幔柱有关。来自欧洲天线的GPS监测数据显示了地球表面的轻微运动，这是地幔柱上升的潜在迹象。地幔柱是地球地幔内炽热岩石的上升流，为火山活动提供了原料。

Scientists believe one such mantle fed ancient volcanism in the mountainous Eifel region in western Germany and eastern Belgium.

科学家们认为，坐落于德国西部和比利时东部之间的艾费尔山区，这样的地幔助长了古代火山活动。

The region is known for its many maars - shallow volcanic craters filled with water.

该地区以其众多的玛珥低平火山口（maar）——以盛满水的浅火山坑而闻名。

A large explosion rocked Eifel some 13,000 years ago, comparable in power to the 1991 eruption of Mount Pinatubo in the Philippines.

大约13000年前，艾费尔发生了一次大爆炸，其威力堪比1991年菲律宾皮纳图博火山(Mount Pinatubo)喷发。

Scientists from the University of Nevada, Reno; and the University of California, Los Angeles suspect the plume is still active.

来自内华达大学雷诺分校和加州大学洛杉矶分校的科学家怀疑该地幔柱仍然活跃。

Study lead author Corné Kreemer said: "Most scientists had assumed that volcanic activity in the Eifel was a thing of the past.

研究报告的第一作者克雷默·科恩（Corne Kreemer）说:“大多数科学家都认为艾菲尔火山的活动已成为过去。

"But connecting the dots, it seems clear that something is brewing underneath the heart of northwest Europe."

“但把这些点连在一起，似乎可以清楚地看到，在欧洲西北部的心脏地带，正在酝酿着某种东西。”

The researchers combined data from commercial and privately owned GPS antennas all over western Europe to chart how the ground is moving vertically and horizontally

研究人员结合了来自西欧各地的商用和私人GPS天线的数据，绘制了地面垂直和水平移动的图表。

Surface movement can reveal how the planet's crust is pushed stretched and sheared.

地表运动可以揭示地球的地壳是如何被挤压、拉伸和断裂的。

The new study revealed that the land in the Eifel region is moving upward and outward.

新的研究表明，艾菲尔地区的土地正在向上和向外移动

The movement covers a large area of land centred on Eifel and including Luxembourg, eastern Belgium and Limburg, a southern province of the Netherlands.

这场运动覆盖了以艾费尔为中心的大片土地，包括卢森堡、比利时东部和荷兰南部的林堡省。

Professor Kreemer said: "The Eifel area is the only region in the study where the ground motion appeared significantly greater than expected.

克雷默教授说:“艾菲尔地区是研究中唯一地震动明显大于预期的地区。

"The results indicate that a rising plume could explain the observed patterns and rate of ground movement."

“结果表明上升的羽流可以解释观测到的地面运动的模式和速度。”

The study's results complemented the findings of another study published in Geophysical Journal International.

这项研究的结果补充了发表在《国际地球物理杂志》上的另一项研究的发现。

The previous study found seismic evidence of magma moving under the Laacher See, a volcanic caldera lake in western Germany.

之前的研究发现，地震证据表明，岩浆在德国西部的拉切湖(Laacher See)之下移动。

Both studies suggest the Eifel region still sits on top of an active volcanic system.

两项研究都表明，艾菲尔地区仍然位于一个活跃的火山系统之上。

Although the study's do not warn of an immediate risk of eruption, the findings imply there could be an increased volcanic and seismic risk in this part of Europe.

尽管该研究没有警告火山爆发的直接风险，但研究结果表明，在欧洲的这个地区，火山爆发和地震的风险可能会增加。

The researchers said: "This does not mean that an explosion or earthquake is imminent, or even possible again in this area.

研究人员说:“这并不意味着即将发生爆炸或地震，或者灾害可能再次发生在这个地区。”

"We and other scientists plan to continue monitoring the area using a variety of geophysical and geochemical techniques in order to better understand and quantify any potential risks."

“我们和其他科学家计划使用各种地球物理和地球化学技术继续监测该地区，以便更好地理解和量化任何潜在风险。”

The study was published in Geophysical Journal International.

这项研究发表在《国际地球物理杂志》上。

In their paper, the researchers wrote: "The fact that the Eifel Anomaly is located above the Eifel plume suggests that the plume causes the anomaly.

在他们的论文中，研究人员写道:“事实上，艾菲尔异常位于艾菲尔羽流之上，这表明异常是由羽流造成的。

"Indeed, we show that buoyancy forces induced by the plume at the bottom of the lithosphere can explain this remarkable surface deformation."

“事实上，我们表明，由岩石圈底部的羽流所产生的浮力可以解释这种显著的表面变形。”
