Bardarbunga volcano update: no significant changes in ongoing eruption
Freitag Okt 03, 2014 19:29 | VON: T
Eruptive activity at the Holuhraun fissure continues with little changes. Large amounts of lava continue to erupt from the active fissure vents. Lava fountains are now mostly hidden inside the growing cinder cones along the fissure.
SO2 gas output remains very significant - IMO estimates that 35,000 tons per day are being released each day into the atmosphere, producing a gas plume typically drifting eastwards and affecting air quality in eastern Iceland.
The caldera of Bardarbunga central volcano continues to subside at approx. 0.5 m per day, presumably as a result of magma draining from underneath there into the dyke, totaling more than 30 m so far - a process now often called "slow caldera collapse". Earthquake activity overall has decreased, but is still present under the northern extrusive dyke.
No one can predict the future development of this large and unusual eruption: The most likely scenarios are that 1) it might go on for a while to come, gradually decrease; 2) it could result in catastrophic collapse of the caldera with a resulting potentially large explosive eruption there; 3) it could open new eruptive fissures above the intrusion, possibly under the ice and cause large floods and ash emissions.
It could as well do something completely different. The next weeks to months will probably tell!

Eruptive activity at the Holuhraun fissure remains stable. The lava flows continue to expand towards the north and particularly to the east, now over a snow-covered landscape as winter conditions set in. ... [mehr]

No significant changes have occurred at the ongoing eruption in Holuhraun and the seismic crisis. The eruption itself continues with steady, very large lava output and is on its way to become the largest event in the past 150 years on Iceland. ... [mehr]

The fissure eruption in Holuhraun continues with similar intensity as during the past days and shows no sign of stopping soon. The latest satellite images indicate that the lava now flows into two main branches, one (the older one) to the north and a new one to the east. ... [mehr]
