Abstract

In this work, A-DInSAR (Advanced-Differential SAR Interferometry) techniques have been applied to study ground motion in the surroundings of Boo, Asturias (N Spain). For this purpose, 57 SAR images from the Sentinel-1 A satellite were processed between February 2018 and January 2020 by means of the PSIG (Persistent Scatterer Interferometry of Geomatics Division of CTTC) software. The results allowed identifying mean deformation velocities in the Line-of-Sight direction (LOS) ranging from –35.9 to 13.5 mm year–1. The evidence detected during the fieldwork has allowed relating these velocities with small slope movements and structural pathologies of houses and buildings. This study reveals the usefulness of A-DInSAR techniques for the study and analysis of slope stability in urban environments.
