Iceland’s authorities have raised its aviation warning level to red following a new eruption from a fissure near the Bardarbunga volcano.

The eruption was described as “a very calm lava eruption” by the met office and it could not be seen on seismometers.

Planes are banned from flying within 6,000 feet of the volcano peak, however this should not impact on most commercial planes which fly higher than that.

Iceland’s Eyjafjallajokull volcano erupted in 2010, which led to severe disruptions to air travel.
