Underground volcanic eruption in Iceland

There has been a small volcanic eruption under Europe’s largest glacier in Iceland. No eruption has yet breached the surface of the glacier but on Saturday authorities raised the warning code for aviation to red, the highest level, and closed the airspace above the Bardarbunga volcano after the eruptions began. On Sunday Iceland lowered its aviation alert level from red to orange, implying that there is still the possibility of an above ground eruption but the threat was not imminent.

Thousands of earthquakes have been recorded under the glacier over the past week. An Icelandic police statement said "Because of pressure from the glacier cap, it is uncertain whether the eruption will stay sub-glacial or not." Authorities have previously warned that any eruption could result in flooding north of the glacier. Several hundred people have been evacuated from the surrounding area.

The 2010 eruption of the Eyjafjallajokull volcano produced an ash cloud that caused more than 100,000 flights to be cancelled across the UK and the rest of the world.
