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.
