Digital Elevation Models, Material Properties, and Landslide Scaling Data from Analogue Models of Volcanic Flank Collapse

This dataset contains the digital elevation models (DEMs), physical-property measurements, and landslide-scaling data generated from analogue experiments investigating volcanic flank deformation and landslide processes. The DEM dataset documents the three-dimensional topographic evolution of the experimental models at different stages of deformation and failure. The accompanying physical-property data include CM2 analogue-material parameters obtained from ring shear testing, together with the parameters and calculations used to establish the landslide scaling relationship and determine the landslide-equivalent scalar seismic moment. The dataset also includes the analogue landslide inventory and associated scaling analysis, documenting the location, geometry, volume, and other relevant characteristics of experimentally produced landslides. These data provide the primary quantitative measurements and derived parameters used for the analysis of model topography, material behavior, landslide characteristics, and their scaling to natural volcanic landslides.
