On 15 August park rangers noted unusually high water in the Volgu River, which originates from a water-filled depression called Gengissig in a geothermal area of Kverkfjöll; the high water destroyed a walking bridge. The next day an overflight of the area by members of National Commissioner of the Icelandic Police (NCIP), the Icelandic Meteorological Office (IMO), and the Institute of Earth Sciences revealed that Gengissig was empty and that a phreatic explosion had deposited streaks of dark material on the rock and snow.

Deformation History


There is data available for 1 deformation periods. Expand each entry for additional details.


Deformation during 2007 Feb - 2008 Apr [uplift; Observed by GPS, InSAR]

Start Date: 2007 Feb Stop Date: 2008 Apr Direction: uplift Method: GPS, InSAR
Magnitude: 6.000 cm Spatial Extent: Unknown Latitude: Unknown Longitude: Unknown

Remarks: A deep dyke intrusion at Upptyppingar in the Kverkfjoll volcanic system was likely ehanced by a retreating ice cap.

Satellite radar and GPS data, and corresponding model results. a,b, Ascending track 230 spanning 27 June 2007 to 16 July 2008. c,d, Descending track 467 spanning 14 July 2007 to 28 June 2008. a and c show the observations with each colour fringe representing 28 mm of displacement toward the satellite. b and d show the modelled radar displacements together with horizontal GPS velocities, observed in black, with 95% confidence ellipses, and modelled in white. Also shown are the surface projections of the model source patches given in Fig. 3 (white rectangles), and catalogue earthquake epicentres for the entire intrusion period27 (black circles).

Photo Gallery


Kverkfjöll, seen here from the north, is a large subglacial volcano at the NE end of the Vatnajökull icecap. The Dyngjujökull glacier, an outflow sheet of the Vatnajökull icecap, appears in the foreground during a 1977 glacial surge. Two elliptical ice-filled calderas, 8 x 5 km in diameter, have been identified at Kverkfjöll volcano. An associated fissure swarm can be traced 60 km to the NE. Subglacial historical eruptions have been recorded since the mid-17th century.

Kverkfjöll volcano (upper right) is seen here from Snæfell mountain, located to the ENE across the Bruarjökull glacier, an outflow sheet of the vast Vatnajökull icecap. A fissure system extends 60 km to the NE of Kverkfjöll, which is the northernmost of a half dozen volcanoes located on the Vatnajökull icecap.
