This paper presents a simple analytical model for estimating rock glacier age by coupling the ratio of frontal advance to total rock glacier length and the ratio of debris volume in the rock glacier to present debris flux in the talus cone-rock
glacier transition zone. The model was applied to 2 rock glaciers at Prins Karls Forland, Svalbard. The main goal of the model is to produce a reasonable estimate of rock glacier initiation age and corresponding rockwall retreat rates, based on geometrical

The aim of this paper is an analysis of tephra accumulation on a pre-eruption winter snow cover and its influence on permafrost aggradation. Based on multi-annual field observations at the Hekla volcano, southern Iceland, a conceptual model
