Bardarbunga volcano update: Eruption continues with little changes

Mittwoch Sep 10, 2014 15:51 | VON: T

No significant changes have occurred. The eruptive activity at Holuhraun continues at similar levels as during the previous days. Lava fountains were strong from the central vents on the main fissure this morning.
Adapted from IMO's latest status report:
Lava flows continue to travel east and north, where lava is flowing in the river bed of Jökulsá á Fjöllum. No explosive activity due to the lava and river water interaction has been observed, but steam rises from the lava.
The eruption is producing significant amounts of SO2 gas, dangerous for people if caught in the plume near the eruption site. Smell of sulfur has been reported as far as Norway.
Earthquake activity has continued to slow down. Only around 80 earthquakes have been recorded during the first half of the day. The largest two earthquakes, M 5.5 and M 4.9 occurred on the northern rim of Bárðarbunga caldera. Low frequency tremor is similar to what has been observed in the last few days.
GPS observations show insignificant crustal movements supporting the assumption that the amount of magma flowing into the dyke continues to be similar to the magma erupted to the surface.

Three scenarios are still considered most likely:

1 Subsidence of the Bárðarbunga caldera stops and the eruption on Holuhraun declines gradually.
2 Large-scale subsidence of the caldera occurs, prolonging or strengthening the eruption on Holuhraun. In this situation, it is likely that the eruptive fissure would lengthen southwards under Dyngjujökull, resulting in a jökulhlaup and an ash-producing eruption. It is also possible that eruptive fissures could develop in another location under the glacier.
3 Large-scale subsidence of the caldera occurs, causing an eruption at the edge of the caldera. Such an eruption would melt large quantities of ice, leading to a major jökulhlaup.

Other scenarios cannot be excluded
