Bardarbunga volcano update: Eruption continues, fluctuating lava supply rates
Dienstag Nov 25, 2014 15:58 | VON: T
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.
Earthquakes and subsidence of the Bardarbunga caldera since 12 Sep (Icelandic Met Office)
It is thought that most of the magma comes from decompressing mantle material at approx. 10 km depth, i.e. directly from the Icelandic hot spot. The observed fluctuations could (but not necessarily does) mean that the magma supply has starting to decrease overall and/or that the dyke started to close up.
Earthquake activity under the caldera remains strong with frequent quakes in the magnitude 3-4 and occasional ones of magnitudes 5-5.4.
Subsidence of the caldera continues with little changes and amounts to 25 meters since 12 Sep.

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

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. ...

The Holuhraun fissure eruption continues with amazing stability. By now, more than 1 cubic kilometers of magma has been erupted and covers almost 70 square km (which implies an average thickness of 15 meters). ... [mehr]
