Abstract

This paper describes and emphasises the role of rapid snowmelt as a mechanism for the release of debris flows in a sub-polar basaltic fjord setting. Post-event mapping of erosional and depositional landforms showed strong geomorphic impacts of debris flows and their role in mass transfer in a mountainous environment. The denudation rate for the single event is estimated. The use of a new lichen growth curve provides relative dating of previous unreported events. Finally, the paper estimates the mean return period for debris-flow events in the Gleidarhjalli area as 4-5 years, thus constituting a serious threat to the community
