As a surface process occurring at the interface between the atmosphere and the crust, landslides are regulated by multiple factors, including topography, precipitation, erosion processes, and vegetative land cover. Earthquake shaking and fault creep associated with tectonic activities further destabilize hillslopes, produce loose materials, and facilitate landslide movements in the form of dynamic failures or temporary acceleration. Quantifying landslide dynamics is still challenging due to the stochastic nature and subjective simplification of mechanical models and lab analogues. Observations of morphologic features and surface deformation provide direct evidence to help infer the underlying rheology, basal geometry, and hydroclimatic feedbacks. This study will present explicit spatiotemporal deformation details from the Slumgullion landslide in Colorado and SF East Bay Hills landslides in California, resolved by …
