A new thermal image of the Holuhraun eruption site, shot from the air, reveals a glowing underground lava river. The river originates in the crater, flows under solidified lava to the northeast and extends 14 km (8 miles) to the edge of the new lava field.
Scientists say there is a slight and ongoing decrease in volcanic and seismic activity at the site of the Holuhraun volcanic eruption in Iceland, which has been going on for over three months.
Photographer Ragnar Axelsson (aka RAX) made this third flight over the Holuhraun eruption on Monday.
Pollution from the eruption in Holuhraun has resulted in acid snow which has been accumulating in the highlands. Scientists are concerned that the acid levels in rivers and lakes may rise sharply when the snow melts in the spring.
Sulfur dioxide (SO2) pollution from the eruption in Holuhraun in Höfn, Southeast Iceland, has reached 1,340 mµ/m3 this morning. The pollution is expected to move to North and Northeast Iceland this afternoon.
If the Holuhraun volcanic eruption continues as it has done, then both the sinking of Bárðarbunga and the eruption itself can be expected to continue for at least several more months.
Over the last day there have been four earthquakes of equal strength measured in the area around the Holuhraun volcanic eruption.
The Scientific Advisory Board has reviewed data about the development of events in Bárðarbunga volcano and the volcanic eruption in Holuhraun from the beginning of the unrest until present day. The new lava field is the largest in Iceland since the Laki eruption (1783-1784) and probably the third...
