Abstract

We present a point-based inventory of landslide events at Møns Klint, Denmark. It is compiled from a Danish Nature Agency (Naturstyrelsen) event list, quality-controlled by adding sources where possible and georeferenced from the listed place names to derive best-estimate cliff localities representing potential source areas. The dataset is provided as a GeoPackage and an Excel file containing metadata on date/temporal precision, location, event type, size class and source. The inventory contains 63 events, spanning from 1801 to 2024. Limitations include locality name uncertainty, variable temporal precision, uncertainty in landslide size and type, and reporting bias related to spatial accessibility and uneven documentation through time. The inventory suggests that landslides are relatively evenly distributed across the cliff. They occur throughout the year but cluster in winter and spring. The inventory provides a baseline for operational monitoring and hazard communication at Møns Klint and supports further research on event frequency, spatial distribution and links between landsliding and potential drivers such as coastal erosion, hydro-meteorological forcing and freeze–thaw processes. The dataset may also serve as a template for developing a national landslide-event inventory for Denmark.
