- Abstract
[EN] 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 the place where marine and terrestrial processes converge, making it highly vulnerable to the effects of climate change. However, the lack of information on the frequency of these extreme weather events and their impacts on the coast hampers an accurate analysis of the consequences of global change. This paper provides a detailed analysis of the extreme weather events (EWE) that have affected the Atlantic and Mediterranean coasts of Southwest Europe during the period from 1 January 2009 to 28 February 2020, as well as a quantification of their impacts: fatalities, injuries and economic damage. Official sources from France, Portugal and Spain were consulted, along with technical reports, scientific articles, etc., to generate a unified database. A total of 95 significant extreme events have caused 168 fatalities, 137 injuries and almost €4000 M in direct economic losses. Cyclone Xynthia (February 2010) on the French Atlantic coast stands out, having caused 47 fatalities, 79 injuries and substantial economic losses valued at €3000 M. The study shows a slight upward trend in the number of events recorded, especially during the last three years of the analysis, as well as in human losses and damages. The results reveal a higher exposure of the Mediterranean coast of Southwest Europe when compared to the Atlantic, especially the Spanish Mediterranean coast, with 61% of the fatalities recorded there during the study period. This is primarily due to a model of exponential tourism growth on the Mediterranean coast, with an enormous urban and infrastructure development during the last decades. Traditionally, the Mediterranean coast is less prepared to reduce the effects of marine storms, extreme events that are becoming more frequent and virulent in the context of c

- Abstract
[EN] Slope failures, subsidence, earthworks, consolidation of waste dumps, and erosion are typical active deformation processes that pose a significant hazard in current and abandoned mining areas, given their considerable potential to produce damage and affect the population at large. This work proves the potential of exploiting space-borne InSAR and airborne LiDAR techniques, combined with data inferred through a simple slope stability geotechnical model, to obtain and update inventory maps of active deformations in mining areas. The proposed approach is illustrated by analyzing the region of Sierra de Cartagena-La Union (Murcia), a mountainous mining area in southeast Spain. Firstly, we processed Sentinel-1 InSAR imagery acquired both in ascending and descending orbits covering the period from October 2016 to November 2021. The obtained ascending and descending deformation velocities were then separately post-processed to semi-automatically generate two active deformation areas (ADA) maps by using ADATool. Subsequently, the PS-InSAR LOS displacements of the ascending and descending tracks were decomposed into vertical and east-west components. Complementarily, open-access, and non-customized LiDAR point clouds were used to analyze surface changes and movements. Furthermore, a slope stability safety factor (SF) map was obtained over the study area adopting a simple infinite slope stability model. Finally, the InSAR-derived maps, the LiDAR-derived map, and the SF map were integrated to update a previously published landslides’ inventory map and to perform a preliminary classification of the different active deformation areas with the support of optical images and a geological map. Complementarily, a level of activity index is defined to state the reliability of the detected ADA. A total of 28, 19, 5, and 12 ADAs were identified through ascending, descending, horizontal, and vertical InSAR datasets, respectively, and 58 ADAs from the LiDAR change detection map. The

- Abstract
[EN] This paper analyses the performance of SAR-based results to support emergency management operations during the volcanic crisis of La Palma island. Tajogaite eruption began on September 19th 2021 affecting a high populated area and the surrounding farmland, used for different agricultural purposes. SAR datasets obtained from Sentinel-1, COSMO-SkyMED, PAZ-TerraSAR-X and Capella satellites, were processed to calculate amplitude, coherence and differential interferograms. These results have permitted to map the morphology of the volcanic cone, the evolution of lava flows and the regional displacements. The comparison of the results obtained with the different satellites has been useful to understand their performance during an emergency scenario triggered by a volcanic eruption. COSMO-SkyMED has provided the most useful information for the analysis of the cone morphology and the lava flows. Sentinel-1 showed the best performance for regional displacements monitoring, whereas PAZ results was the second best option for all the retrieved products.

Deformation processes, both natural (e.g., subsidence, landslides, active tectonics) and induced (e.g., associated with mining, construction. groundwater exploitation), result in significant socioeconomic losses worldwide. Accurate detection and classification of these processes are crucial for effective risk management. In this study, we present a novel approach for the automatic classification of deformation processes using Interferometric Synthetic Aperture Radar (InSAR) data and machine learning techniques. Specifically, we use a decision tree-based classification algorithm to train a model capable of recognizing and distinguishing different types of deformation processes using time series of displacements, grouped into Active Deformation Areas (ADAs). We test this methodology in a large area in SE Spain. Our results demonstrate promising performance, with an Area Under the Curve (AUC) > 0.95, identifying several covariates of morphometric, geological, hydrogeological, and geotechnical nature as key factors. This automatic classification of InSAR data holds significant implications for risk management associated with ground deformation, providing a potentially valuable tool for decision makers in urban planning and land management officials.

Minería - Abstract
En esta investigación se propone una metodología de análisis de estabilidad de taludes en zonas mineras basada en la combinación de técnicas de monitorización (remota e in situ) y modelización numérica, aplicable tanto a escala regional como local, y centrada en la aplicación de la interferometría radar satélite (InSAR) como principal técnica de monitorización. La aplicación de la metodología propuesta, cuyo fin último no es otro que el de reducir el riesgo asociado a la posible ocurrencia de roturas de talud (o simplemente a la existencia de inestabilidades de talud) en minería, facilita la interpretación de los resultados obtenidos con las diferentes técnicas aplicadas, y ofrece distintas posibilidades para la integración de los mismos, lo que permite aportar gran valor añadido a los datos InSAR satélite brutos. Además, la metodología puede utilizarse para realizar tanto análisis (predictivos) de inestabilidades de talud, como análisis (retrospectivos) de roturas de talud. El trabajo está estructurado en tres bloques. El primero de ellos describe cada una de las partes de la metodología desarrollada, incluyendo una descripción detallada de las técnicas de monitorización y modelización necesarias para aplicar el flujo de trabajo propuesto. El segundo, recoge los resultados obtenidos en tres zonas de estudio, seleccionadas principalmente atendiendo a criterios de aplicabilidad, tipología, complementariedad y disponibilidad de información. Finalmente, el tercer bloque resume las principales conclusiones de la investigación. La metodología consta de cuatro pilares: (i) aplicación de técnicas de monitorización multi-sensor (técnicas InSAR, técnicas de fotogrametría digital o SfM, y técnicas de navegación por satélite diferencial o DGNSS) multi-plataforma (satélite, aérea y terrestre), y de técnicas de validación de datos (validación de los resultados de monitorización), (ii) aplicación de métodos de análisis espaciotemporal de datos (análisis de los resultados de monitorización), (iii) aplicación de técnicas de modelización numérica (mediante modelización por elementos finitos o FEM), y (iv) aplicación de técnicas de integración de datos (integración de los resultados de monitorización y modelización). El segundo bloque presenta los resultados obtenidos tras aplicar la metodología en los tres casos de estudio considerados: la Sierra Minera de Cartagena-La Unión (Murcia), la mina de Las Cruces (Sevilla) y la mina de El Feixolín (León). Así, sobre la base de los trabajos llevados a cabo en la Sierra Minera, esta tesis documenta, por primera vez, la aplicación de técnicas FEM al análisis de estabilidad de taludes en zonas mineras a escala regional (análisis predictivo), así como la elaboración de mapas de peligrosidad por inestabilidad de taludes mediante la combinación de técnicas InSAR y FEM. Asimismo, gracias a los trabajos llevados a cabo en Las Cruces, este trabajo muestra las posibilidades que ofrece la combinación de técnicas InSAR, SfM y FEM a la hora de realizar análisis remotos (es decir, basados exclusivamente en la explotación de datos de teledetección) de roturas de talud en zonas de minería a cielo abierto a escala local (análisis retrospectivo). Por último, este estudio documenta por vez primera, en base a los trabajos realizados en El Feixolín, la aplicación de técnicas SfM a la monitorización de inestabilidades de talud en zonas mineras a escala local (análisis predictivo), poniendo además de manifiesto las ventajas asociadas a la adopción, para la gestión del riesgo por inestabilidad de taludes, de programas de monitorización basados en la combinación de técnicas InSAR y SfM. Estos trabajos han ayudado a demostrar la eficacia de la metodología propuesta para analizar, en los casos de estudio investigados, características geomorfológicas, áreas fuente, volúmenes movilizados, desplazamientos a lo largo de la línea de vista del satélite, aspectos sobre la predictibilidad de la rotura, diferencias de elevación, desplazamientos 3D, factores condicionantes y desencadenantes, y mecanismos de rotura. Aunque, en todos los casos, la aplicación de la metodología desarrollada en esta tesis se ha centrado en el análisis de inestabilidades y roturas de talud en zonas mineras, conviene señalar que dicha metodología puede utilizarse para analizar todo tipo de movimientos de ladera. ----------ABSTRACT---------- This research proposes a methodology for slope stability analysis in mining areas, based on the combination of (remote sensing and in situ) monitoring and numerical modeling techniques, applicable at both regional and local scales, and focusing on the application of satellite radar interferometry (InSAR) as the main monitoring technique. The application of the proposed methodology, its ultimate aim being none other than to reduce the risk associated with the possible occurrence of slope failure (or simply the existence of slope instabilities) in mining, facilitates the interpretation of the results obtained with the different techniques applied, and offers different possibilities for their integration, which allows to provide great added value to the raw satellite InSAR data. Furthermore, the methodology can be used to perform both (predictive) analyses of slope instabilities and (retrospective) analyses of slope failures. The work is structured in three sections. The first describes each part of the methodology developed, including a detailed description of the monitoring and modeling techniques needed to apply the proposed workflow. The second one gathers the results obtained in three study areas, selected mainly according to criteria of applicability, typology, complementarity, and availability of information. Finally, the third section summarizes the main conclusions of the research. The methodology consists of four pillars: (i) application of multi-sensor (InSAR techniques, digital photogrammetry techniques or SfM, and differential satellite navigation techniques or DGNSS), multi-platform (satellite, airborne and terrestrial) monitoring techniques, and of data validation techniques (validation of the monitoring results), (ii) application of spatiotemporal data analysis methods (analysis of the monitoring results), (iii) application of numerical modeling techniques (using finite element modeling techniques or FEM), and (iv) application of data integration techniques (integration of the monitoring and modeling results). The second section presents the results obtained by applying the methodology in the three case studies considered: Sierra Minera de Cartagena-La Unión (Murcia), Las Cruces mine (Seville) and El Feixolín mine (Leon). Thus, on the basis of the work conducted at Sierra Minera, this thesis reports for the first time the application of FEM techniques to perform slope stability analysis in mining areas on a regional scale (predictive analysis), as well as the elaboration of slope instability hazard maps by combining InSAR and FEM techniques. In addition, thanks to the study carried out at Las Cruces, this work shows the possibilities offered by the combination of InSAR, SfM and FEM techniques to perform remote analysis (i.e., based exclusively on the exploitation of remote sensing data) of slope failures in open-pit mining areas on a local scale (retrospective analysis). Finally, this study documents for the first time, based on the investigations conducted at El Feixolín, the application of SfM techniques to the monitoring of slope instabilities in mining areas on a local scale (predictive analysis), further highlighting the advantages associated with the adoption, for slope instability risk management, of monitoring programs based on the combination of InSAR and SfM techniques. The proposed methodology has proven to be effective for analyzing, in the investigated case studies, geomorphological features, source areas, mobilized volumes, displacements along the satellite line of sight, aspects on the failure predictability, elevation differences, 3D displacements, conditioning and triggering factors, and failure mechanisms. Although, in all cases, the application of the methodology developed in this thesis has focused on the analysis of slope instabilities and failures in mining areas, it should be noted that this methodology can likewise be used to analyze all types of instabilities and failures affecting natural and man-made slopes.

- Abstract
[EN] The island of Gran Canaria (Canary Islands, Spain) is characterized by a large variability of volcanic rocks reflecting its volcanic evolution. The geological map provided by Geological Survey of Spain at 1:25.000 scale shows more than 109 different lithologies and it is too complex for environmental and engineering purposes. This work presents a simplified geotechnical map with a small number of classes grouping up units with similar geotechnical behaviours. The lithologies were grouped using about 350 rock samples, collected in the seven major islands of the Archipelago. The geotechnical map was used to model rockfall hazard in the entire island of Gran Canaria, where rockfalls are an important threat. The rockfall map was validated with 128 rockfall events along the GC-200 road, located in the NW sector of Gran Canaria. About 96% of the events occurred along sections of the road where the number of expected trajectories is high or moderate.

- Abstract
Aquifer overexploitation can lead to the irreversible loss of groundwater storage caused by the compaction or consolidation of unconsolidated fine-grained sediments resulting in land subsidence. Advanced Differential SAR Interferometry (A-DINSAR) is particularly efficient to monitor progressive ground movements, making it an appropriate method to study depleting aquifers undergoing overexploitation and land subsidence. The Guadalentín River Basin (Murcia, Spain) is a widely recognized subsiding area that exhibits the highest rates of groundwater-related land subsidence recorded in Europe (>10 cm/yr). The basin covers an extension of more than 500 km2 and is underlain by an overexploited aquifer-system formed by two contiguous hydraulically connected units (Alto Guadalentín and Bajo Guadalentín). Although during the last years the piezometric levels have partially stabilized, the ongoing aquifer-system deformation is evident and significant, as revealed by the A-DInSAR analysis presented. In this work, we submit the first vertical and horizontal (E-W) decomposition results of the LOS velocity and displacement time series of the whole Guadalentín Basin obtained from two datasets of Sentinel-1 SAR acquisitions in ascending and descending modes. The images cover the period from 2015 to 2021 and they were processed using the Parallel Small BAseline Subset (P-SBAS) implemented by CNRIREA in the Geohazards Exploitation Platform (GEP) on-demand web tool, which is funded by the European Space Agency. The output ascending and descending measurement points of P-SBAS lie on the same regular grid, which is particularly suited for the geometrical decomposition. Time series displacements are compared to a permanent GNSS station located in the Bajo Guadalentín basin.

- Abstract
[EN] Detecting and monitoring slope movements is essential to better understand their causes and mitigate their adverse consequences. Satellite radar interferometry (InSAR) techniques allow to generate deformation maps at high resolution (both spatial and temporal), especially since 2014, when the European Space Agency's Sentinel-1 mission (6-day revisit frequency) became operational. The application of InSAR is, however, constrained by a number of limitations. The main one relates to the inability of the technique to measure rapid deformation phenomena. In the case of Sentinel-1, for example, the maximum measurable deformation rate (along the satellite line of sight) is about 0.85 m/year. In this context, the application of digital photogrammetry (SfM) orthoimagery correlation techniques constitutes a directly applicable alternative for the remote monitoring of rapid slope movements. Moreover, whereas the application of InSAR monitoring techniques in densely vegetated areas is often impractical given the decorrelation produced by strong changes in the vegetation cover, the application of SfM monitoring techniques allows more effective analyses to be conducted in areas with abundant vegetation.

[EN] The pilotSTRATEGY (2021-2026) is investigating geological CO2 storage sites in industrial regions to support development of large-scale carbon capture and storage (CCS). It is focused on deep saline aquifers–porous rock formations filled with brine several kilometres below ground – which promise a large capacity for storing captured CO2. The goal of the characterisation is to assess the site’s containment, injectivity, capacity, integrity, hydrodynamics, and monitorability in order to ensure safe and permanent storage of CO2. PilotSTRATEGY covers the initial stages of project development up to the pre-final investment decision (pre-FID), regulatory approval and permitting of storage, and applied on selected structures of Paris Basin in France, the Lusitanian Basin in Portugal and the Ebro Basin in Spain, and in lower detail, in West Macedonia in Greece and Upper Silesia in Poland.

The presence of IGME in other administrations (ministries, autonomous communities, hydrographic confederations, city councils) is vital and is one of its symbols of identity. Our presence in numerous autonomous communities allows a very close knowledge of the territory . Undoubtedly, all these changes have generated uncertainties in the staff of the Institute, but little by little they will become certainties revealed in the improvement of the services and infrastructures of the IGME, including the GeoMining Museum. Proof of this is the Recovery and Resilience Plan, which has made it possible to acquire new equipment that will also contribute to the modernization of our laboratories. This Proceedings book is tangible proof of the excellence of the scientific-technical work carried out at the IGME, and of the quality of its infrastructures. It shows a modern IGME aligned with the Sustainable Development Goals and focused on the Ecological Transition. And above all, it shows a magnificent human team, capable of carrying out multidisciplinary research, in collaboration with many other institutions. The scientific-technical conferences have been a success in terms of participation, contents and organization. They would not have been possible without a great team made up of Jorge Jódar, Teresa Llorens, Jorge Colmenar, César Husillos, Blanca Martínez, Juan López and Ignacio Marzán, thanks to all of them for their enthusiastic work and for making the IGME have a Happy Birthday.

[EN] Aquifer overexploitation can lead to the irreversible loss of groundwater storage caused by the compaction or consolidation of unconsolidated fine-grained sediments resulting in land subsidence. Advanced Differential SAR Interferometry (A-DINSAR) is particularly efficient to monitor progressive ground movements, making it an appropriate method to study depleting aquifers undergoing overexploitation and land subsidence. The Guadalentín River Basin (Murcia, Spain) is a widely recognized subsiding area that exhibits the highest rates of groundwater-related land subsidence recorded in Europe (>10 cm/yr). The basin covers an extension of more than 500 km2 and is underlain by an overexploited aquifer-system formed by two contiguous hydraulically connected units (Alto Guadalentín and Bajo Guadalentín). Although during the last years the piezometric levels have partially stabilized, the ongoing aquifer-system deformation is evident and significant, as revealed by the A-DInSAR analysis presented. In this work, we submit the first vertical and horizontal (E-W) decomposition results of the LOS velocity and displacement time series of the whole Guadalentín Basin obtained from two datasets of Sentinel-1 SAR acquisitions in ascending and descending modes. The images cover the period from 2015 to 2021 and they were processed using the Parallel Small BAseline Subset (P-SBAS) implemented by CNR-IREA in the Geohazards Exploitation Platform (GEP) on-demand web tool, which is funded by the European Space Agency. The output ascending and descending measurement points of P-SBAS lie on the same regular grid, which is particularly suited for the geometrical decomposition. Time series displacements are compared to a permanent GNSS station located in the Bajo Guadalentín basin., This study has received funding in framework of the RESERVOIR project (Sustainable groundwater RESources managEment by integrating eaRth observation deriVed monitoring and flOw modelIng Results), funded by the Partnership for Research and Innovation in the Mediterranean Area (PRIMA) programme supported by the European Union (Grant Agreement 1924; https://reservoir-prima.org/).

Deslizamiento ladera ,Satélite InSAR ,Ortoimagen - Abstract
[EN] Detecting and monitoring slope movements is essential to better understand their causes and mitigate their adverse consequences. Satellite radar interferometry (InSAR) techniques allow to generate deformation maps at high resolution (both spatial and temporal), especially since 2014, when the European Space Agency's Sentinel-1 mission (6-day revisit frequency) became operational. The application of InSAR is, however, constrained by a number of limitations. The main one relates to the inability of the technique to measure rapid deformation phenomena. In the case of Sentinel-1, for example, the maximum measurable deformation rate (along the satellite line of sight) is about 0.85 m/year. In this context, the application of digital photogrammetry (SfM) orthoimagery correlation techniques constitutes a directly applicable alternative for the remote monitoring of rapid slope movements. Moreover, whereas the application of InSAR monitoring techniques in densely vegetated areas is often impractical given the decorrelation produced by strong changes in the vegetation cover, the application of SfM monitoring techniques allows more effective analyses to be conducted in areas with abundant vegetation.

- Abstract
[EN] Groundwater is one of the most important hydric resources of the Spain territory. Nevertheless, heavy groundwater withdrawal generates severe consequences, being land subsidence one of them. The Interferometric Synthetic Aperture Radar (InSAR) technique have been recently exploited to detect and monitor aquifer related deformations. In the present work, relationship between piezometric levels drawdowns and land subsidence has been studied for the higher withdrawals areas within Almonte-Marismas aquifer system (which holds the Doñana Natural Space). Four datasets of radar satellite images, obtained from Sentine-1 satellite, have been processed using the InSAR technique in the period 2014 - 2020. Results show that in some of these areas, like those surrounding El Rocío and Matalascañas villages, the correlation between these two variables is high., [ES] El agua subterránea es uno de los recursos hídricos más importantes en el territorio español. La gran cantidad de agua que se retira de ellos puede tener graves consecuencias, entre las que destaca, en algunos acuíferos, la subsidencia del terreno. La técnica de interferometría radar (InSAR), ha sido desarrollada en las últimas décadas para detectar y monitorear las deformaciones relacionadas con los acuíferos. En este trabajo se estudia la posible relación existente entre la variación de los niveles piezométricos y el movimiento del terreno en zonas con grandes extracciones del acuífero Almonte-Marismas (sobre el que se ubica el Espacio Natural de Doñana). Para ello, se han analizado los datos de deformación del terreno obtenidos del satélite Sentinel-1 en el periodo 2014-2020 Los resultados muestran que, en alguna de estas zonas, como las cercanas a las poblaciones de El Rocío y Matalascañas, la correlación entre ambas variables es alta.

- Abstract
When an active landslide is first identified in an artificial reservoir, a comprehensive study has to be quickly conducted to analyse the possible hazard that it may represent to such a critical infrastructure. This paper presents the case of the El Arrecife Landslide, located in a slope of the Rules Reservoir (Southern Spain), as an example of geological and motion data integration for elaborating a preliminary hazard assessment. For this purpose, a field survey was carried out to define the kinematics of the landslide: translational in favour of a specific foliation set, and rotational at the foot of the landslide. A possible failure surface has been proposed, as well as an estimation of the volume of the landslide: 14.7 million m3. At the same time, remote sensing and geophysical techniques were applied to obtain historical displacement rates. A mean subsidence rate of the landslide around 2 cm/year was obtained by means of synthetic aperture radar interferometry (InSAR) and ground-penetrating radar (GPR) data, during the last 5 and 22 years, respectively. The structure-from-motion (SfM) technique provided a rate up to 26 cm/year during the last 14 years of a slag heap located within the foot of the landslide, due to compaction of the anthropical deposits. All of this collected information will be valuable to optimise the planning of future monitoring surveys (i.e. differential global positioning systems, inclinometers, ground drilling, and InSAR) that should be applied in order to prevent further damage on the reservoir and related infrastructures.

- Abstract
Subsidence, the lowering of Earth's land surface, is a potentially destructive hazard that can be caused by a wide range of natural or anthropogenic triggers but mainly results from solid or fluid mobilization underground. Subsidence due to groundwater depletion (1) is a slow and gradual process that develops on large time scales (months to years), producing progressive loss of land elevation (centimeters to decimeters per year) typically over very large areas (tens to thousands of square kilometers) and variably affects urban and agricultural areas worldwide. Subsidence permanently reduces aquifer-system storage capacity, causes earth fissures, damages buildings and civil infrastructure, and increases flood susceptibility and risk. During the next decades, global population and economic growth will continue to increase groundwater demand and accompanying groundwater depletion (2) and, when exacerbated by droughts (3), will probably increase land subsidence occurrence and related damages or impacts. To raise awareness and inform decision-making, we evaluate potential global subsidence due to groundwater depletion, a key first step toward formulating effective land-subsidence policies that are lacking in most countries worldwide.

- Abstract
Persistent scatterer interferometry (PSI) is a group of advanced interferometric synthetic aperture radar (SAR) techniques used to measure and monitor terrain deformation. Sentinel-1 has improved the data acquisition throughout and, compared to previous sensors, increased considerably the differential interferometric SAR (DInSAR) and PSI deformation monitoring potential. The low density of persistent scatterer (PS) in non-urban areas is a critical issue in DInSAR and has inspired the development of alternative approaches and refinement of the PS chains. This paper proposes two different and complementary data-driven procedures to obtain terrain deformation maps. These approaches aim to exploit Sentinel-1 highly coherent interferograms and their short revisit time. The first approach, called direct integration (DI), aims at providing a very fast and straightforward approach to screen-wide areas and easily detects active areas. This approach fully exploits the coherent interferograms from consecutive images provided by Sentinel-1, resulting in a very high sampling density. However, it lacks robustness and its usability lays on the operator experience. The second method, called persistent scatterer interferometry geomatics (PSIG) short temporal baseline, provides a constrained application of the PSIG chain, the CTTC approach to the PSI. It uses short temporal baseline interferograms and does not assume any deformation model for point selection. It is also quite a straightforward approach, which improves the performances of the standard PSIG approach, increasing the PS density and providing robust measurements. The effectiveness of the approaches is illustrated through analyses performed on different test sites., This work has been partially funded by AGAUR, Generalitat de Catalunya, through a grant for the recruitment of early-stage research staff (Ref: FI_B 00741) and through the Consolidated Research Group RSE, “Remote Sensing” (Ref: 2017-SGR-00729).

- Abstract
The island of Gran Canaria (Canary Islands, Spain) is characterized by a large variability of volcanic rocks reflecting its volcanic evolution. The geological map provided by Geological Survey of Spain at 1:25.000 scale shows more than 109 different lithologies and it is too complex for environmental and engineering purposes. This work presents a simplified geotechnical map with a small number of classes grouping up units with similar geotechnical behaviours. The lithologies were grouped using about 350 rock samples, collected in the seven major islands of the Archipelago. The geotechnical map was used to model rockfall hazard in the entire island of Gran Canaria, where rockfalls are an important threat. The rockfall map was validated with 128 rockfall events along the GC-200 road, located in the NW sector of Gran Canaria. About 96% of the events occurred along sections of the road where the number of expected trajectories is high or moderate.

- Abstract
This work describes the set of tools developed, tested, and put into production in the context of the H2020 project Multi-scale Observation and Monitoring of Railway Infrastructure Threats (MOMIT). This project, which ended in 2019, aimed to show how the use of various remote sensing techniques could help to improve the monitoring of railway infrastructures, such as tracks or bridges, and thus, consequently, improve the detection of ground instabilities and facilitate their management. Several lines of work were opened by MOMIT, but the authors of this work concentrated their efforts in the design of tools to help the detection and identification of ground movements using synthetic aperture radar interferometry (InSAR) data. The main output of this activity was a set of tools able to detect the areas labelled active deformation areas (ADA), with the highest deformation rates and to connect them to a geological or anthropogenic process. ADAtools is the name given to the aforementioned set of tools. The description of these tools includes the definition of their targets, inputs, and outputs, as well as details on how the correctness of the applications was checked and on the benchmarks showing their performance. The ADAtools include the following applications: ADAfinder, los2hv, ADAclassifier, and THEXfinder. The toolset is targeted at the analysis and interpretation of InSAR results. Ancillary information supports the semi-automatic interpretation and classification process. Two real use-cases illustrating this statement are included at the end of this paper to show the kind of results that may be obtained with the ADAtools.

- Abstract
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 to be a reliable method to monitor the activity of landslides in such contexts. Here, we present a DInSAR (Differential Interferometric Synthetic Aperture Radar) analysis of Sentinel-1 images that exemplifies the usefulness of the technique to recognize and monitor landslides in the Rules Reservoir (Southern Spain). The integration of DInSAR results with a comprehensive geomorphological study allowed us to understand the typology, evolution and triggering factors of three active landslides: Lorenzo-1, Rules Viaduct and El Arrecife. We could distinguish between rotational and translational landslides and, thus, we evaluated the potential hazards related to these typologies, i.e., retrogression (Lorenzo-1 and Rules Viaduct landslides) or catastrophic slope failure (El Arrecife Landslide), respectively. We also observed how changes in the water level of the reservoir influence the landslide’s behaviour. Additionally, we were able to monitor the stability of the Rules Dam as well as detect the deformation of a highway viaduct that crosses a branch of the reservoir. Overall, we consider that other techniques must be applied to continue monitoring the movements, especially in the El Arrecife Landslide, in order to avoid future structural damages and fatalities.

- Abstract
[EN] An enquiry-based and participatory analysis approach is carried out to identify the strengths and weaknesses in the heterogeneous legislations across Europe that regulate the integration of landslide hazard into urban planning. Twenty one national and eight regional Geological Surveys (GSs) have participated in the analysis. The GSs report almost 4000 recent (2015–2017) damaging landslides events resulting in 39 fatalities and 155 injuries, destruction to housing, infrastructure and properties. In addition, 11 countries report 18 MORLE events over the past 10 years responsible for 150 fatalities and severe economic impacts. Results also reveal almost 48 million people living in areas with high and very high degrees of landslide-susceptibility (around 1 million km2 according to ELSUS v2). This work shows that almost half the participating countries (10 countries) have no legal guidance in the National Land Bill to stipulate consideration of landslides in urban planning practices, and mapping tools are often not adapted to a standard required to inform sustainable development. Furthermore, there is a wide range of laws and a large heterogeneity of mapping methods, scales and procedures. A relevant deficiency detected in many countries is the lack of landslide maps at a detailed resolution for urban planning. Additionally, some case studies of suboptimal urban development practices in areas of known instability have been discussed; they are found to be related to weak rule of law and/or absence of good governance. This paper shows inconsistencies across Europe in the handling of landslides and proposes a series of key actions to improve this situation, highlighting the need for a common regulatory framework to deal with this geohazard appropriately.
