A small lava-eruption has been detected under the Dyngjujökull glacier.
The Icelandic Coast Guard airplane TF-SIF is flying over the area with representatives from the Civil Protection and experts from the Icelandic Met Office and the Institute of Earth Sciences. Data from the equipment on board is expected later today.
Data from radars and webcameras are being received, showing no signs of changes at the surface.
The estimate is that 150-400 meters of ice is above the area.
The aviation color code for the Bárðarbunga volcano has been changed from orange to red.
Scientists at the Icelandic Met Office believe that a small sub-glacial volcanic eruption has now started under the icecap of Dyngjujökull glacier in the Northern part of Vatnajökull glacier. Because of this the National Commissioner of the Icelandic Police has raised the alert phase to emergency phase.
