needs to be based on an understanding of the dynamics of granular flows against obstructions that lead to a change in the flow direction, slow the flow down or cause it to stop. Laboratory experiments have been performed in recent years with granular material in order to shed light on the dynamics of avalanche flow over and around braking mounds and catching dams and to estimate the retarding effect

to volcanic eruptions must be made. An integrated risk assessment consists of an evaluation of potential hazard and the vulnerability of society, followed by an estimate of the corresponding risk and of feasible counter-measures in order to prevent accidents and minimise economic damage.
The work on a general risk assessment will be organized in accordance with the risk assessment framework

that the avalanche would have been many times larger, and that it might have reached the health care centre, if the supporting structures had not reduced the released snow volume by an order of magnitude.
This is the first example of supporting structures preventing or reducing the size of a snow avalanche in Iceland.
Supporting structures for preventing snow avalanches have been installed

Substantial changes have taken place in the climate of the Nordic countries in the last 20-30 years and changes on the same order of magnitude are expected until the middle of the 21st century. It was clear from many presentations at the conference that energy companies have already taken recent changes in climate and the consequent changes in hydrology into account in their operations. The companies
