The eruption is thought to have began at 4AM in approximately the same place where an eruption occured Friday night.
Below are the pictures that Armann Hoskuldsson took this morning. No scientists are on site at the moment since weather conditions are very tough.
"This time it's a considerable eruption, which is evident by the 3 kilometer long lava flow that it formed in only 3 hours. The upstream from the fissure is considerable," says geophysicist Magnús Tumi Guðmundsson. More on his views and explanations in English here.
Magma started flowing in Holuhraun at 5:00 AM this morning. The eruption is located on the same fissure as the previous eruption on Friday morning, but is many times larger. This is the third eruption in the Bárðarbunga region in roughly a week, and the largest by far.
An eruption has started again in Holuhraun, just north of Dyngjujokull in Iceland. The eruption was visible from a live webcam at 5:49 AM local time.
