Abstract
This work presents retreat measurements obtained along a 400 m long cliff section located in the Podes Peninsula (43º 37‘ 35’ ‘N, 5º 54’ 4 ‘’ W; Peñas Cape, N Spain). In this cliff, 30 m high and developed on Devonian limestone, dolomite and marl, active coastal erosion and slope movements are observed (Jiménez-Sánchez et al., 2019). The methodology included i) the acquisition and processing of SAR data from Sentinel-1 satellite (from 2018 to 2020), ii) the generation of ground deforma- tion velocity maps and deformation time series by means of the PSIG software and the GEP service, iii) the comparison of DInSAR results with the displacement measurements from 9 topographic nails and 12 pheno survey markers installed in the area and obtained with a total station between 2018 and 2020. The results confirm the need to combine several monitoring techniques in the analysis of retreating cliffs.
