Abstract
En este trabajo se han aplicado las técnicas A-DInSAR (Interfe rometría SAR Diferencial Avanzadas) para estudiar los movimientos
del terreno en el entorno de Boo, Asturias (N España). Para ello se
procesaron 57 imágenes SAR del satélite Sentinel-1 A entre febrero
de 2018 y enero de 2020 por medio del software PSIG (Persistent
Scatterer Interferometry de la División de Geomática del CTTC). Los
resultados permitieron identificar velocidades medias de deforma ción en la dirección suelo-satélite (LOS) que van desde –35,9 hasta
13,5 mm/año. Las evidencias detectadas durante el trabajo de cam po han permitido relacionar estas velocidades con movimientos de
ladera de pequeñas dimensiones y con patologías estructurales de
viviendas y edificaciones. Este estudio pone de manifiesto la utilidad
de las técnicas A-DInSAR para el estudio y análisis de estabilidad de
laderas en entornos urbanos
In this work, A-DInSAR (Advanced-Differential SAR Interferome try) 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 Fe bruary 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 the se velocities with small slope movements and structural pathologies of houses and buildings. This study reveals the usefulness of A-DIn SAR techniques for the study and analysis of slope stability in urban environments
