The lava eruption on Holuhraun in Iceland (Askja) extended over a 3-km2. This corresponds to a magma discharge of 300 to 500 cubic meters per second. From observations, the volume of erupted lava is between 16 and 25 million cubic meters. The eruption has not created any ash-fall.Gas and steam rises to a couple of hundred meters above the eruption site, extending up to 1,200 m downwind. In connection with the FUTUREVOLC project, a gas monitoring station has been set-up near to the eruption site. Gas measurements indicate a high level of sulphur dioxide (So2). People could be exposed to highly dangerous gas levels close to the eruption. It is essential that those working near the eruption site are equipped with gas sensors and gas masks.
Seismic activity in the area in still stable. Over 10.000 earthquakes have been recorded. Most of the seismicity is occurring on the northern end of the dyke intrusion, covering a 15-km-long region that extends partly beneath Dyngjujökull and north of the ice margin.
