2008: Dendrogeomorphology as a tool to unravel snowavalanche activity; preliminary results from the Fnjóskadalur test site, Northern Iceland. Norsk Geografisk Tidsskrift
Snow avalanches are a major hazard for many settlements and transportation corridors in northern Iceland. At many sites the occurrence of snow avalanches during the past century has not been recorded. Visible damage, such as tilting, scars and decapitation of trees and shrubs (Betula pubescens) grow...
