yesterday, earthquake activity began in
Grímsvötn. The largest earthquakes were of magnitude 3 and several
were larger than magnitude 2.5. As the tremor levels increased, it
became more difficult to detect the earthquakes. After 19h, the
seismicity decreased at the same time that the tremor reached a
maximum.

days. Five earthquakes bigger then M3,0 were recorded
since noon yesterday, the largest M5,5 at 13:42 yesterday.
Smaller earthquakes were detected in north part of the dyke and around the eruption site. Weather conditions at
the moment, however, make smaller earthquakes difficult to detect.
GPS measurements show minor, irregular movements.
No change was detected in water monitoring

prior to significant earthquakes, adequate data are often lacking to test the hypothesis of
preseismic signals. Using earthquake data in order to detect such signals, errors in earthquake locations
and velocity models may give a false-positive temporal signals. For the detection of a low level
(~1.0%) preseismic change, good knowledge of seismic structure, high accuracy

avalanches. During this period, tremendous progress has been made in minimising
the impact of avalanches. Acceptable risk has been defined, and law and
regulations set about avalanche mitigation, prevention and fortification. In
many avalanche-prone towns and villages protection dams have been built (e.g.
in Siglufjörður, see photo). These engineering solutions and the Early Warning

Vision for Proactive Climate Change Adaptation in the Danish Water Sector
Speaker: Helle Katrine Andersen, DANVA hka@danva.dk
To inspire water utilities to develop climate change adaptation strategies and to implement
CC adaptation solutions The Danish Water and Waste Water Association (DANVA) has
developed a vision for Proactive Climate Change Adaptation in the Water Sector
