“…How to include these factors and their associated probabilities in PTHA is not resolved. While advanced numerical models for landslide dynamics exist (e.g., Tinti et al, 1997;Jop et al, 2006;Savage et al, 2014;Si et al, 2018a;Si et al, 2018b;Kim et al, 2019;Wang et al, 2019;Gallotti and Tinti, 2020), their complexity and variety obfuscate understanding on which models are most suitable to be used. Furthermore, some models (e.g., Savage et al, 2014;Si et al, 2018a;Si et al, 2018b) are presently too comprehensive to be used in PTHA.…”
