    • Norge - et overraskende snøskred-land 

      Jaedicke, Christian; Kronholm, Kalle (Journal article, 2008)
      Det er ikke helt passende å påstå at vestlendinger, nordlendinger og finnmarkinger er forskjellige av natur. Men snøskredene i de tre regionene er åpenbart forskjellige: Skred utløses ofte av nedbør på Vestlandet, av ...
