  Institution description
  • The Icelandic Meteorological Office (IMO) is a governmental institute responsible for producing regular and specific weather forecasts. It's Avalanche Section is responsible for avalanche warnings, evacuations, hazard zoning and is the scientific advisor to the Icelandic government in the field of avalanche defense structures.
  • The Avalanche Section at the IMO was strengthened considerably after the avalanche disasters in the villages Súđavík and Flateyri in 1995. The staff increased from 2 to 8 and we have been able to broaden our range of expertise. Although the Office has since 1979 been responsible for issuing avalanche warnings, it has since December 1995 been given the added responsibility for ordering evacuations, both evaluating the extent of, and deciding upon their timing.
  • The IMO is responsible for avalanche hazard zoning in Iceland. New methods have being developed and tested in the hope that better and safer zoning will result. Research projects have been carried out regarding risk and risk management. Hazard maps have been made and are being made for several villages.
  • The government of Iceland has undertaken the task of constructing avalanche protection measures for the communities at risk. The brunt of the scientific part of that work has been carried out by the IMO resulting in a rapid buildup of expertise in that field. Several research projects and field experiments have been undertaken as part of the avalanche defense project. They include a pilot project installation of avalanche supporting structures, to investigate their effectiveness and decide upon design criteria for Iceland. The interaction between avalanches and deflecting walls and retarding mounds has been studied, and also snow accumulation around retaining walls and mounds. In addition, theoretical investigations and modelling are being performed regarding the flow of avalanches.
  • The IMO is also involved with several other kinds of research within the fields of meteorology and geosciences.
