Bardarbunga volcano update: Eruption continues

The eruption continues with little changes. While most of the lava now remains on top of the already emplaced lava field, more than 75 square km large, several lateral outbreaks are active as well.
Thermal image from 1 Dec. shows considerable magmatic activity in the lava and in just over 24 hours it has stretched about 450 m to NNA through the new extrusion at the northeastern margin. West of the lava lake, the lava river now branches towards north. The southern margin is also active; a new extrusion seems to be forming due south from the lava lake and something similar is taking place just east of that. On this image, the plume appears like a brownish cloud over the middle part of the lava field and pillows of steam still seem to hover over the eastern part. Contrarily, the green effects are simply artefacts and tricks of light. (Image: Institute of Earth Sciences)
The most active one, to the north, has advanced more than 450 m in a single day.
Seismic activity remains high under the volcano - yesterday, 2 earthquakes above magnitude 2 occurred under Bárðarbunga. No significant earthquake activity occurs under the erupting dyke, suggesting the situation is stable.

The eruption continues at similar intensity as during the past weeks. It also continues to produce spectacular images and videos such as this one from an overflight in late November: ... [mehr]

These two images were posted on the twitter account of the University of Iceland after their recent field expedition. As the lava field continues to expand, new branches of red hot rivers reach its edge and cascade down on the sandy plain below in a spectacular ‘water’fall of glowing lava. Scientists report that by now the Holuhraun lava field covers almost 75 square kilometres which represents an area bigger than the Reykjavik metropolitan area. ... [mehr]

The eruption at Holuhraun continues strongly. The only apparent change is that during the past days, the intensity of lava output seems to be less stable and fluctuating. ... [mehr]

Winter conditions continue to make it difficult to study the fissure eruption at Holuhraun. Rare opportunities for visual observation however revealed that the Baugur crater ceased to eject tall lava fountains and transformed into an elongated, boiling lava lake. Magma seems to be welling up in this lava lake at the same effusion rate as early November. The two images accompanying this update are snapshots from a stunning video recently shot by Jon Gustafson. ... [mehr]
Bardarbunga volcano update: Continuing eruption formed a 70 km² lava flow and caused 44 m of caldera subsidence since its onset on August 31
Sonntag, Nov 09, 2014
The volcanic eruption at Holuhraun gives no signs of weakening and continues to eject an impressive lava fountain from the central Baugur crater at a rate similar to the past few weeks. This record-breaking eruption started on the 31st of August 2014 and formed a more than 17 km long lava flow. Using the successive outlines of this lava flow as drawn on a radar image from the Icelandic Coast Guard, researchers from the Institute of Earth Sciences estimated that by now the lava has covered an area of 70 km². ...
