Location map of the study area. Solid triangles mark the headscarp locations of the study landslides. Hollow triangles are the locations of other landslides of ~ 1020 cal BP (after Brooks 2015). Dotted lines are some major faults of interest in the region (after Atkinson et al. 2014, Bent et al. 2015, and Lamontagne et al. 2020)
