Fractures, about four to six kilometers long, have formed north of Vatnajökull outlet glacier Dyngjujökull, northeast of Bárðarbunga, as reported by RÚV, visir.is and the Icelandic Met Office. Small calderas (also known as lows or cauldrons) have formed in the glacier and it cannot be ruled out that an eruption has started.
According to the Civil Protection Department, there is no indication of a flood yet, but the department's director Víðir Reynisson told RÚV television just now (at 10:20 pm) that it would be hard to explain what has occurred if not caused by an eruption.
Everyone concerned is very cautious in light of the false alarm on Saturday, but the new calderas are thought to have been formed by heat from below.
Iceland Review will provide updates as soon as reports arrive from the Icelandic Met Office and others.
