the volcano. Question: Should an eruption occur, where from the glacier can
the jökulhlaup be expected?Answer: It depends on the
location and type of the eruption. Three types of glacial outbursts can be
thought about:Floods resulting from an eruption
in the caldera, where the ice is up to 500 m thick. Large eruptions can melt of order 100,000 m3/s.
Jökulhlaups can be expected from Virkisjökull

revealed.
Gas measurements
Driving toward the western side of the crater a degassing vent releasing brownish gases was identified.
The site is 10 min walking across the lava field and presents decoloration of rocks. Some gas
measurements have been done with two different type of sensors (standard personal and Alphasens
ones).
Peak concentration of 7 ppm SO2 and 9 ppm CO were observed
