measurements
and analyses have been carried out, especially on the part that is in
the lake and regarding the depth of the sliding surface. If the bot-
tom of the slide reaches below the lake bottom, the total volume of
material that moved may be a lot more.
The water level of Lake Öskjuvatn rose 1–2 m after the rockslide. The
rise of the water level will be measured precisely because it gives

The hydrological simulations were performed with the Wa-
tershed Simulation and Forecasting System (WSFS) developed
and operated in the Finnish Environment Institute (Vehviläinen
et al., 2005). The WSFS is used in Finland for operational hydrolog-
ical forecasting and flood warnings (www.environment.fi/water-
forecast/), regulation planning and research purposes

of
Greenland and Antarctica appear to be driven by changes in basal sliding that are most likely
caused by variations in the amount and pressure of basal water. As a part of lidar mapping of
the surface of glaciers and ice caps in Iceland 2008–2012, some source areas for jökulhlaups
(glacier outburst floods) have been surveyed more than once. These include the Skaftá
cauldrons in western
