Snow avalanches at Interpraevent 2021

The 14th Interpraevent congress, that was planned to be arranged in Bergen in May 2020, was postponed one year and hosted digitally from Norway last week. Some of the presentations were dealing with snow avalanches in Norway and the rest of Europe.

Interpravenet is an international research society, based in Klagenfurt in Austria, «that works to set up preventive protection against disasters and supports interdisciplinary research to protect our living space against flooding, debris flow, avalanches and mass movements». Therefore, it deals with more natural hazards than ‘Norskred’ does. However, it focuses on risk assessments in general terms that could also be relevant for snow avalanche mitigation.

Anyhow, for the benefit of Norskred members; below you will find some publicly available highlights from the congress redgarding snow topics.

The congress in 2021 was arranged by NVE, NGI and NPRA.

Digitital excursions (storymaps)

Since the congress was held digitally, the planned excursions were obviously impossible to perform. Instead, a handful storymaps were made from different locations in Norway. Three of them dealt with snow avalanches. Click on images or links below to join «digital excursions» (Storymaps) to Stavbrekka in Skjåk, Ryggfonn in Stryn, and Aga and Bleie in Ullensvang.
