摘要：

We used C-band data from the ESA satellites (ERS, ENVISAT and SENTINEL-1) to map ground motion patterns in the vicinity of Evinos dam in central Greece. The stability of the body of the dam was also examined. In the dam reservoir area, we obtained displacements up to 17 mm/year along the line of sight (LOS) in the vicinity of village Klepas (ENVISAT dataset; 2003-2010). Several active landslides in the InSAR data were confirmed on the field (September 2017). Regarding the dam body, ENVISAT data show no significant deformation (less than 7 mm/year along the LOS). The SENTINEL-1 data (up to 2017) continue to show the same behaviour, however, a periodic signal and differential deformation on the dam body of the order of -8 mm/year along the LOS were detected and needs further investigation. We also mapped small ground motions inside several villages upstream the dam. A new landslide inventory for the dam upstream area was created from optical data.
