Flow velocity variations and surface change of the destabilised Plator rock glacier (Central Italian Alps) from aerial surveys
Flow velocities were measured on the Plator rock glacier in the Central Italian Alps using a cor-relation image analysis algorithm on orthophotos acquired by drones between the years 2016 and 2020. The spatial patterns of surface creep were then compared to the Bulk Creep Factor (BCF) spatial variab...
