“Hard to Explain what Happened if not Caused by an Eruption”
Rifts, about four to six kilometers (2.4 to 2.6 miles) long, have formed in Vatnajökull outlet glacier Dyngjujökull northeast of Bárðarbunga, according to the Icelandic Met Office and RÚV, visir.is .
Small calderas have also formed in the glacier and it cannot be ruled out that an eruption has started. The new calderas are thought to have been formed by heat from below.
According to Víðir Reynisson, director of the Civil Protection Department, there is no indication of a flood yet, but it would be hard to explain what has occurred if not caused by an eruption.
Seismic activity in Bárðarbunga was greater last night than the night before, with 500 earthquakes between midnight and 6 am. That included two larger earthquakes, one 5.3 about 2.5 km southeast of Bárðarbunga and another of 5.2 some 9.6 km east-northeast of Bárðarbunga.
