It is also considered likely that rainfall and snowmelt
in recent months have caused unusually high water pressure in cracks and
fractures in the area which further weakened the starting area of the landslide.The landslide causes considerable damageThe run-out angle of the landslide is 12–13° which means that the run-out
is relatively long in comparison with other large landslides. The slide

the uncertainty is great. For simplicity, the earthquakes are positioned with sea level as a referral plane.
Coloured patches on the surface represent the 20 most recent earthquakes. As the coloured patches move on they leave a gray color, which consequently shows where the activity has been. Doing is learning and our users are encouraged to test out the interactive possibilities:

Mechanic failure 12-14 October. A short break 8 Nov., processing failure due to connection problems. The apparent rise 11 November, when the station had to be lifted out of snow, has been corrected for. From 23 Nov. to 30 Dec no signal received (the station was out of sight of the relay station in Kverkfjöll). After trial
