Article: What Happens When A Volcano Erupts Under A Glacier?

A major volcano in Iceland is showing signs of erupting. It is under a glacier. What will happen?

Short answer, no one knows what will happen this time.

Iceland has experienced several eruptions like this over the last few years. It depends on how thick the ice is, how thick the lava is, how much lava coming out, and several other factors.

Because one recent volcanic eruption in Iceland caused plane flight issues all over Europe, this one is being closely monitored.
