Persistently unstable hillslopes in Northern California are ideally suited to the study of the dynamics and morphological signature of earthflows, as the deeply sheared melange lithology, high seasonal rainfall, and fast uplift rates promote widespread deep-seated landsliding. In addition to identifying multiple active landslides in the region, L-band InSAR reveals varying deformation rates in the accumulation, transport, and toe regions of the Boulder Creek earthflow. Downslope displacement rates up to 1.8 m/yr are observed on the earthflow over a I-year period. The pattern of deformation is similar to that observed from 1944-2006 inferred from aerial photography. Interferograms highlight spatially variable rates controlled by lithology and gullies, and movement correlates with seasonal rainfall with a phase lag of ~2 months.en-USEarthflows -- California -- Boulder CreekThesis
