Simulation and modeling output and geospatial data from the 2023 Peters Dome landslide (Alaska)

This data release includes four files supporting Toney and others (2026), a study of the 2023 Peters Dome landslide. The Peters Dome landslide was a 6.1 million m3 ice–rock avalanche in Denali National Park and Preserve (Alaska) that occurred on September 13, 2023, local time. The coordinates of the source area are (63.1423°, -151.1871°). The files are: A CSV file of the forces exerted on the Earth by the landslide as inferred from displacement seismograms (peters_dome_15-200_s_jackknife.csv), a NetCDF file of numerical flow model outputs for a simulation of the Peters Dome landslide (shaltop_run_0520.nc), a post-event digital elevation model (DEM) created from a stereo optical image pair (setsm_aligned_UTM5N_DEM_resampled.tif), a shapefile containing outlines of the Peters Dome landslide source and deposit geometry (dem_diff_source_sar_diff_total.zip), an image of Figure 7 from Toney and others (2026) (toney_et_al_figure_7.png), and a metadata file (simulation_and_modeling_output_and_geospatial_data_from_the_2023_Peters_Dome_landslide_Alaska.xml).
