Landslides recurrently impact the Italian territory, producing huge economic losses and casualties. Because of this, there is a large demand for monitoring tools to support landslide management strategies. Among variety remote sensing techniques, Interferometric Synthetic Aperture Radar (InSAR) has become one most widely applied studies. This work reviews InSAR-related applications studies in Italy. More than 250 papers were analyzed this review. The first application dates back 1999....
This work is focused on deformation activity mapping and monitoring using Sentinel-1 (S-1) data the DInSAR (Differential Interferometric Synthetic Aperture Radar) technique. The main goal to present a procedure periodically update assess geohazard (volcanic activity, landslides ground-subsidence) of given area by exploiting wide coverage high coherence temporal sampling (revisit time up six days) provided S-1 satellites. products are two updatable maps: map active areas map. These maps...
This paper illustrates the potential of Sentinel-1 for landslide detection, mapping and characterization with aim updating inventory maps monitoring activity. The study area is located in Molise, one smallest regions Italy, where processes are frequent. results achieved by integrating Differential Synthetic Aperture Radar Interferometry (DInSAR) deformation time series, Geographical Information System (GIS) multilayer analysis (optical, geological, geomorphological, etc.) shown. adopted...
This work describes a new procedure aimed to semi-automatically identify clusters of active persistent scatterers and preliminarily associate them with different potential types deformational processes over wide areas. consists three main modules: (i) ADAfinder, at the detection Active Deformation Areas (ADA) using Persistent Scatterer Interferometry (PSI) data; (ii) LOS2HV, focused on decomposition Line Of Sight (LOS) displacements from ascending descending PSI datasets into vertical...
Landslides in reservoir contexts are a well-recognised hazard that may lead to dangerous situations regarding infrastructures and people’s safety. Satellite-based radar interferometry is proving be reliable method monitor the activity of landslides such contexts. Here, we present DInSAR (Differential Interferometric Synthetic Aperture Radar) analysis Sentinel-1 images exemplifies usefulness technique recognize Rules Reservoir (Southern Spain). The integration results with comprehensive...
Multi-Temporal Interferometric Synthetic Aperture Radar (MTInSAR) data offer a valuable support to landslide mapping and activity estimation in mountain environments, where situ measures are sometimes difficult gather. Nowadays, the interferometric approach is more used for wide-areas analysis, providing useful information risk management actors but at same time requiring lot of efforts correctly interpret what satellite telling us. In this context, hot-spot-like analyses that select...
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...
Land subsidence resulting from groundwater extractions is a global phenomenon adversely affecting many regions worldwide. Understanding the governing processes and mitigating associated hazards require knowing spatial distribution of implicated factors (piezometric levels, lithology, ground deformation), usually only known at discrete locations. Here, we propose methodology based on Kriging with External Drift (KED) approach to interpolate sparse point measurements variables influencing land...
The detection of active movements that could threat the infrastructures and population is one main priorities risk management chain. Interferometric Synthetic Aperture Radar (InSAR) techniques represent most useful answers to this task; however, it difficult manage huge amount information derived from interferometric analysis. In work, we present a procedure for deriving impact assessment maps, over regional test site, using as starting point Sentinel-1 SAR (Synthetic Radar) images catalogue...
This work describes the set of tools developed, tested, and put into production in context H2020 project Multi-scale Observation Monitoring Railway Infrastructure Threats (MOMIT). project, which ended 2019, aimed to show how use various remote sensing techniques could help improve monitoring railway infrastructures, such as tracks or bridges, thus, consequently, detection ground instabilities facilitate their management. Several lines were opened by MOMIT, but authors this concentrated...
Displacement time series (TS) provides temporal and spatial information related to ground deformation. This study aims investigate behavior of deformation TS, including classification displacement trends periodicity evaluation, which ease the interpretation movements. To this end, we propose several modifications an existing automatic workflow Persistent Scatterers Interferometry (PSI) TS using new tests classify deformations into seven main trends: Stable, Linear, Quadratic, Bilinear, Phase...
The intensification of the effects climate change on mountainous geohazards underlines critical need for advanced tools to monitor like landslide and permafrost associated hazards. In this study, we present a novel active reflector specifically designed C-band synthetic aperture radar (SAR) applications, optimized Sentinel-1 missions. is engineered receive vertically polarized signals reflect them in both vertical horizontal polarizations, significantly improving signal-to-noise ratio DInSAR...
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.

ABSTRACT The island of Gran Canaria (Canary Islands, Spain) is characterized by a large variability volcanic rocks reflecting its evolution. geological map provided Geological Survey Spain at 1:25.000 scale shows more than 109 different lithologies and it too complex for environmental engineering purposes. This work presents simplified geotechnical with small number classes grouping up units similar behaviours. were grouped using about 350 rock samples, collected in the seven major islands...
The aim of this paper is to demonstrate how the integration differential interferometric synthetic aperture radar (D-InSAR) and levelling improves monitoring ground deformation phenomena, thereby enabling their complete understanding. complementarity between D-InSAR illustrated through a case study construction road tunnel beneath Glòries Square, Barcelona; employed continuously monitor works, notably dewatering site. This focuses primarily on data obtained from processing Sentinel-1A...
According to the United Nations Educational, Scientific and Cultural Organization (UNESCO) agency, World Heritage Sites (WHS) inscribed in List (WHL) must be safeguarded with an adequate protection system, order guarantee their integrity authenticity. Currently, many UNESCO sites are threatened by geohazards, but safeguard of these does not seem wide-ranging. Looking at standard list factors affecting Outstanding Universal Value (OUV) WHS, which has been adopted Committee 2008, it seems that...
This paper is focused on deformation monitoring using a Persistent Scatterer Interferometry technique and the interferometric SAR data acquired by Sentinel-1 satellite of European Space Agency. The first part describes procedure used to process analyze data. Two main approaches are described. one simplified approach that exploits two key properties data: high coherence 12-day interferograms reduced orbital tube. second full approach, where more sophisticate treatment employed. illustrates...
