What Happens When A Volcano Erupts Under A Glacier? | Popular Science

When Iceland’s Eyjafjallajökull volcano blew up in 2010, the relatively small eruption belched out a 30,000-foot-tall plume of ash that shut down airports throughout most of Europe for six days – so you can imagine that people have questions about what’s brewing these days.

Last week scientists registered the area’s largest earthquake since 1996, and they’ve spotted a magma welling beneath the ground, causing Iceland’s Met office to issue a code orange risk level to the aviation industry. On the scale, which comes from the International Civil Aviation Organization, the only thing riskier than orange is red. Now, the Iceland Review reports that areas north of the volcano are being evacuated.

Melting Lava isn’t necessarily a problem when it’s slowly powered onto ice. But when there’s an eruption (especially from under a glacier) things get wonky. We don’t expect to see the volcano break through the glacier it sits under, but it could potentially melt it and there’s two very different opinions about the potential of an ash cloud. Have a look at the video: it’s always fascinating to watching something so hot crawl over ice and cool.. scary stuff if you’re not careful
