Short summary

This study explore the impact of landslides on Alpine terrain using a landscape evolution model called Hyland, which enables long-term topographical analysis. Our finding reveal that landslides are concentrated at two specific elevations over time and predominantly affect the highest and steepest slopes, particularly along ridges and crests. This study is part of a broader question concerning the origin of accelerated erosion during the Quaternary period.
