Landslide susceptibility is commonly assessed using physics-based slope stability models. However, modeling the three-dimensional (3D) mechanics of discrete landslides, on a regional scale, remains challenging. This presentation will discuss RegionGrow3D, a new slope stability approach that models the area, volume, and location of potential landslides across broad regions. This model is paired with forensic estimates of soil shear strength to create a landslide susceptibility framework. Using this framework, rainfall and seismically induced landslide susceptibility is characterized for a study area in the Oregon Coast Range, USA. • Mathews N (2022) A regional-scale three-dimensional susceptibility model for enhanced evaluation of rainfall- and seismically induced landsliding.
