Climate change and landslides in subpolar Alaska: Less ice, more water

Landslide initiation processes in subarctic Alaska are complicated by the prevalence of ice-rich permafrost. Permafrost and permafrost thaw influence landslide type, frequency, and continued ground surface deformation, resulting in positive feedbacks between permafrost thaw and landsliding. Thaw-induced landslides in interior Alaska and rain-induced landslides across the state pose persistent hazards to vulnerable communities throughout Alaska.
