Résumé

The results of structure from motion photogrammetry and SAR interferometry as complementary techniques for measuring ground deformation induced by the massive open-pit landslide in Amyntaio, Greece (June 10, 2017), is presented in this paper. This unexpected slide damaged the entire westernmost marginal area of the pit, significant number of buildings, and infrastructures of the nearby village of Anargiri. The described methodology includes the generation of a multi-temporal dataset (from Sept. 2017 to Sept. 2018) of very high-resolution surface topography (at 10 cm), based on the analysis of imagery collected by Remotely Piloted Airborne Systems (RPASs). Satellite observations involved interferometric processing of TerraSAR-X data for a complementary estimation of ground displacement rates. Height differences from consecutive aerial photography campaigns as well as space-borne measurements provided valuable information on the evolution of the deformation and its spatial characteristics during the post-event period, an important aspect for future hazard and risk considerations.
