Landslides are widespread natural hazards that generate considerable damage and economic losses worldwide. Detecting terrain movements caused by these phenomena characterizing affected urban areas is critical to reduce their impact. Here we present a fast simple methodology create maps of vulnerable buildings slow-moving landslides, based on two parameters: (1) the deformation rate associated each building, measured from Sentinel-1 SAR data, (2) building generated landslide movement recorded...
Land subsidence associated with overexploitation of aquifers is a hazard that commonly affects large areas worldwide. The Lorca area, located in southeast Spain, has undergone one the highest rates Europe as direct consequence long-term aquifer exploitation. Previous studies carried out on region assumed ground deformation retrieved from satellite radar interferometry corresponds only to vertical displacement. Here we report, for first time, two- and three-dimensional displacement field over...
Land subsidence associated with groundwater overexploitation in the Alto Guadalentín Basin (Spain) aquifer system has been detected during last decades. In this work, for first time, we propose a new point cloud differencing methodology to detect land at basin scale, based on multiscale model-to-model comparison (M3C2) algorithm. This method is applied two open-access airborne LiDAR datasets acquired 2009 and 2016, respectively. First internal edge connection errors different flight lines...
Coastal regions in Southwest Europe have experienced major interventions and transformations of the territory with unprecedented urban development, primarily related to growing tourism activity. The coast is place where marine terrestrial processes converge, making it highly vulnerable effects climate change. However, lack information on frequency these extreme weather events their impacts hampers an accurate analysis consequences global This paper provides a detailed (EWE) that affected...
In this article, satellite radar data are analysed to control the deformation of buildings Murcia City (SE Spain) affected by subsidence. This phenomenon has occurred as a result groundwater overexploitation in drought periods, and special attention is paid most recent which between 2005 2008. first part work, study area presented followed description characteristics effects subsidence on urban area. Persistent scatterer interferometry used process base dataset measuring temporal spatial...
Alaşehir-Sarıgöl sub-basin (ASSB) in Türkiye faces severe water stress mainly due to intensive agricultural irrigation. This has led declining groundwater levels, aquifer compaction, and subsequent land subsidence. study aims evaluate the roles of tectonic activity withdrawal land-subsidence investigate additional factors like faults soft soil thickness. The P-SBAS algorithm was applied, using 98 123 Sentinel-1 SAR images ascending descending orbits, respectively, from 2016 2020. Independent...
A recent article using data from the European Ground Motion Service (EGMS) to assess vulnerability of Spanish coastline ground movements was published in October 2024 (López-Vinielles et al., 2024). The study, funded by “Plan de Recuperación, Transformación y Resiliencia - Financiado por la Unión Europea Next Generation EU” programme and conducted within framework RISKCOAST project (Ref. SOE3/P4/E0868), EGMS RASTOOL (Grant Agreement No....
Terrain surface displacements at a site can be induced by more than one geological process. In this work, we use advanced differential interferometry SAR (A-DInSAR) to measure ground deformation in Arcos de la Frontera (SW Spain), where severe damages related landslide activity and subsidence have occurred recent years. The are concentrated two residential neighborhoods constructed between 2001 2006. One of the neighborhoods, called La Verbena, is located head an active retrogressive that...
This paper analyses the performance of SAR-based results to support emergency management operations during volcanic crisis La Palma island. Tajogaite eruption began on September 19th 2021 affecting a high populated area and surrounding farmland, used for different agricultural purposes. SAR datasets obtained from Sentinel-1, COSMO-SkyMED, PAZ-TerraSAR-X Capella satellites, were processed calculate amplitude, coherence differential interferograms. These have permitted map morphology cone,...
Abstract Interferometric synthetic aperture radar (InSAR) is a remote sensing tool used for monitoring urban areas affected by geological hazards. Here we analysed the effectiveness of stabilization works on slow-moving landslide in Arcos de La Frontera (Cádiz, Spain) using persistent scatterer interferometric approach. The consisted jet grouting cement-based injections and were applied locally to stabilize most damaged neighbourhood. We processed large stack Sentinel-1 SAR satellite...
This work addresses the suitability of using X-band Synthetic Aperture Radar (SAR) data for operational geotechnical monitoring site scale slow moving landslides, affecting urban areas and infrastructures. The these studies requires high resolution data. We propose a procedure practical use SAR in landslides campaigns, that includes an appropriate dataset selection taking into account scenario characteristics, visibility analysis, considerations when comparing advanced differential...
Recent studies highlight the fragility of Mediterranean basin against climate stresses and difficulties managing sustainable development groundwater resources. In this work, main issues related to management have been identified from stakeholder’s perspective in following four representative water-stressed areas: coastal aquifer Comacchio (Italy), Alto Guadalentín (Spain), alluvial Gediz River (Turkey), Azraq (Azraq Wetland Reserve, Jordan). This has achieved by designing a methodology...

Land subsidence is a natural or anthropogenic process triggering the settlement of Earths surface. When this phenomenon induced by groundwater withdrawal, compaction unconsolidated sediments causes land displacement. Differential Interferometric Synthetic Aperture Radar (DInSAR) widely used nowadays to monitor over extensive areas. However, validation DInSAR measurements with in-situ techniques lacking in many case studies, reducing reliability further analyses. The aim study propose...
