Öræfajökull
The summit caldera of this stratovolcano is 3 km × 4 km (1.9 mi × 2.5 mi) and the volcano is 20 km (12 mi) in diameter. It is the most southern of the volcanoes in the Öræfi volcanic belt (Öræfajökull volcanic belt), which is possibly an embryonic rift parallel and to the east of the Eastern volcanic zone. The presently active summit caldera may have a subcaldera within it. Eruptions in this area are most likely to result in jökulhlaups that will produce floods at the outlets of the Kviarjökull and Virkisá catchments as these overlap the present caldera. There is possibly an old caldera to the north of the current caldera and flank eruptions could produce jökulhlaup from other outlet glaciers. The topographical map on this page can be enlarged to show this detail.
