Interesting developments detailed in the latest on the Bárdarbunga Volcano, published by the incredible Carl of the Volcano Café. Recommended reading once more. Reblogged with much gratitude.

During a scientific over flight a marked and unexpected drop was noticed in the caldera floor of the Bárdarbunga Central Volcano. The drop was 15 meters, and is as such the largest deformation of a caldera in Iceland. It is interpreted as the result of magma leaving the magmatic reservoir under the caldera floor.
If this number is valid for all of the 11 by 7km caldera it equals to a volume of drained magma of 808 million cubic meters, or just shy of a cubic kilometer. This does not take into account magma that has come into the system during this episode

Since the appropriate Icelandic authorities have today publicly mentioned the possibility of a large, acidic and explosive eruption at Bardarbunga, we now feel free to inform you that this possibility has been discussed by the Dragons, behind closed doors, for well over a week. The key information comes from this official IMO graphic:
The first premise is that earthquakes do not occur in molten rock. Nor do they form a clearly visible ring shape such as the above except under one circumstance – they do so around a body of liquid, in this case magma. A conservative estimate places the size of this body of magma at 8 km diameter, height unknown but most likely on the order of 3 – 6 km, depth also unknown but relatively shallow. Using simple geometry, 4 x Pi x r3 / 3…

Thank you Alvin for posting this update on the Bardabunga Volcano in Iceland. A huge amount of magma has moved so very, very quickly, with a number of potential scenarios being examined as a consequence.
I’m keeping an eye on the Azores Islands, by the way. ‘Why?’, I hear you asking. M3.2 and M3.6 affecting the Azores yesterday evening, Universal Time. Just keep a close eye on the Azores, that is all…
The Extinction Protocol
August 2014 – ICELAND – The magma from Iceland’s Bardarbunga volcano could be moving towards another large volcanic system. Data recorded by a team from the University of Cambridge suggests that 50 million cubic meters of molten rock has moved in the last 24 hours. If it continues on a northern trajectory it could feed into the Askja volcanic system, potentially triggering a large eruption. Prof Bob White said: “It’s headed straight for it.” But he cautioned that volcanoes were hard to predict. “It’s moving at about 4km a day towards Askja, and if it keeps going it will get there in a few days,” he told BBC News. “We know there is a lot of molten rock sitting under the ground beneath Askja, which is a major volcanic system. If this molten rock hits that, we know it is likely to trigger it to erupt. “But who knows, it…
