The Icelandic Coast Guard airplane TF-SIF is taking off from Reykjavík airport for Bárðarbunga. Yesterday the scientists onboard TF-SIF detected a 4-6 km long row of 10-15 m deep and 1 km wide cauldrons on the surface of Vatnajökull glacier. Conditions for surveillance from air were not good when the cauldrons were detected, making it hard to estimate precisely their size. Conditions today are very good, bright and sunny, which will help the scientists to observe the surface of the glacier. News from the flight can be expected around noon.
