    • All-weather avalanche activity monitoring from space? 

      Bühler, Yves; Bieler, Claudia; Pielmeier, Christine; Wiesmann, Andreas; Caduff, Rafael; Frauenfelder, Regula; Jaedicke, Christian; Bippus, Gabriele (The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2014)
      Information on avalanche activity or on non-activity on local and regional scale is of great value for avalanche warning services, traffic authorities and experts responsible for safety in communities or ski resorts. In ...

    • Analysis of an artificially triggered avalanche at the nepheline syenite mine on Stjernøya, Alta, Northern Norway 

      Frauenfelder, Regula; Jónsson, Árni; Lied, Karstein; Schwerdtfeger, Dirk; Bergum, Guro; Bühler, Yves; Stoffe, Lukas (The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2014)
      Since 1961, a Nepheline Syenite mine is operated on the island of Stjernøya in the Altafjord, Northern Norway. The facilities are located in Lillebukt, on the southern side of the island. Above the facilities, the Nabbaren ...

    • Automated Avalanche Deposit Mapping From VHR Optical Imagery 

      Lato, Matthew J.; Frauenfelder, Regula; Bühler, Yves (The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2012)
      Using eCognition we developed an algorithm to automatically detect and map avalanche deposits in Very High Resolution (VHR) optical remote sensing imagery acquired from satellites and airplanes. The algorithm relies on a ...

    • Can big data and random forests improve avalanche runout estimation compared to simple linear regression? 

      Toft, Håvard B.; Müller, Karsten; Hendrikx, Jordy; Jaedicke, Christian; Bühler, Yves (Peer reviewed; Journal article, 2023)
      Accurate prediction of snow avalanche runout-distances in a deterministic sense remains a challenge due to the complexity of all the physical properties involved. Therefore, in many locations including Norway, it has been ...

    • Remote sensing of snow avalanches: Recent advances, potential, and limitations 

      Eckerstorfer, Markus; Bühler, Yves; Frauenfelder, Regula; Malnes, Eirik (Journal article, 2015)
      Snow avalanches are the main natural hazard in snow covered mountainous areas worldwide, frequently threatening lives and infrastructure. Avalanche research is inherently risk research, working towards avalanche risk ...
