Third day of continued eruption from the Grimsvötn volcano, Iceland.
From the second reconnaissance flight yesterday, it was observed that the eruption occurs from a circular vent approx. 1km in diameter in the south-eastern part of the Grimsvötn caldera.

At the homepage of Prof. Magnus Tumi Gudmundsson a detailed map showing the location of the eruption vent as well as additional pictures can be found.
The eruptive activity is pulsating resulting in changing eruption column height from 8-9km up to 13-14km

The distal ash plume has been observed in Norway, Finland and Sweden.
