The magma from Iceland’s Bardarbunga volcano could be moving towards another large volcanic system. “We know there is a lot of molten rock sitting under the ground beneath Askja, which is a major volcanic system. If this molten rock hits that, we know it is likely to trigger it to erupt.

“But who knows, it may just stop. It is still at 5km-depth, and it is possible it could freeze there and not a lot more will happen. That is perfectly plausible.”

Exciting, lets hope its settled down for our visit in February!

An orange alert indicates that a volcano is showing “escalating unrest with increased potential of eruption”, or is erupting without any major volcanic ash emissions.

A red alert means that an eruption is “imminent”, or is underway with “significant emission of volcanic ash into the atmosphere”.

The ash cloud produced by the 2010 Eyjafjallajokull eruption led to hundreds of thousands of passengers being affected by flight restrictions.
