Our study, focused on South Tyrol (NE Italy), develops an updated and comprehensive activity classification system for all rock glaciers in the current regional inventory. Using multisource products, we integrate climatic, morphological, and  differential interferometric synthetic aperture radar (DInSAR) data in replicable routines and multivariate statistical methods, producing a comprehensive classification based on the updated Rock Glacier Inventories and Kinematic (RGIK) 2023 guidelines. Results leave only 3.5 % of the features non-classified, as opposed to 13–18.5 % in previous studies.
