were carried out to obtain the flow and
sliding parameters for Hoffellsjökull that resulted in a good
simulation of the observed 20th century evolution of the
glacier geometry. The obtained values for the rate factor
and the sliding parameter are A= 4.6× 10−15 s−1 kPa−3 and
C = 10× 10−15 m a−1 Pa−3, respectively.

Adaptive management (AM) involves learning from

and our intention is to run these models dur-
ing times of hazardous events and even on a daily
basis to further improve monitoring.
Avalanche monitoring has progressed. The em-
phasis is now on improving our services, especially
to the Icelandic Road and Coastal Administration
with regard to transport. The reason is that com-
munity structure has changed considerably in recent
years and the need

level in Skeidará waned. The last sign of a
crater explosion was seen at GRF early on 6
November, leaving only a weak tremor signal
from the remnants of the jökulhlaup. The
jökulhlaup fi nally ended in early December,
after ~0.8 km3 of water had drained from the
Grímsvötn lake (J. Hardardóttir, personal com-
munication, 2005).

Future improvements should be made in the light of applications within a larger toolbox of scenario
