Gígjökull Glacier Outlet of Eyjafjallajökull by Extreme Iceland During the volcanic eruption of 2010, an immense jökulhlaup – an outburst flood of meltwater – came out of this hole under the glacier. Hundreds of people needed to be evacuated from the area.
This is the largest outlet of Eyjafjallajökull. It’s on the way to Þórsmörk (Thorsmork).
