“…Repeat DEMs obtained at different time periods can provide precise estimates of surface elevation change associated with many processes, including glacier change (e.g., Brun et al, 2017;Willis et al, 2018;Zheng et al, 2019;Shean et al, 2020), snow accumulation/melt (e.g., Deschamps-Berger et al, 2020;McGrath et al, 2019;, volcanic deformation (e.g., Bisson et al, 2021;Schaefer et al, 2012), and landslide or debris flow events (e.g., van Westen and Lulie Getahun, 2003). In particular for landslide research, previous studies have used DEM-differencing techniques to identify geomorphic changes (e.g., Corsa et al, 2022)) and precursory motion (e.g., Higman et al, 2018;Dai et al, 2020a) on timescales ranging from years (e.g., Shugar et al, 2021;Geertsema et al, 2022) to decades (e.g., Higman et al, 2018;Lacroix et al, 2020).…”
