To gain insights into the spatio-temporal nature of calving, we use… Read More

During this period, the rock slope weakened while the precursor movements increased progressively, in particular… Read More

Risk assessment approaches and decision-making strategies have traditionally assumed the stationarity of climatic conditions, including the persistence of historical patterns of natural variability and the likelihood of extreme events. However, climate… Read More

Glacier shrinkage – accelerated over the last decades due to climate change – is exposing large areas in mountain regions worldwide. But an even dire consequence of the melting ice is the forming of more glacier lakes, which are… Read More

(2020). Remote thermal detection of exfoliation sheet deformation. Landslides. https://doi.org/10.1007/s10346-020-01524-1 A growing body of research indicates that rock slope failures, particularly from exfoliating cliffs, are promoted by rock deformations induced by daily temperature cycles. Although previous research has described how these deformations occur, full three-dimensional monitoring of both the deformations and the associated temperature changes has not yet… Read More
