The Chgega landslide, in northern Tunisia, represents a paradigmatic mass movement. It can be classified as a complex landslide, or more specifically as vast rock spreading that evolved into a block slide. It involves a great block of limestone—about 900 m long and 400 m wide—sliding over ductile clays and marls. The viscoplastic creep of the clays drives the landslide and creates, in its crown, a graben ~800 m long and ~120 m wide that breaks the summit of Chgega Mountain. Using Interferometric Synthetic Aperture Radar (InSAR) technologies, we demonstrate that this complex landslide is currently active and moreover shows progressive movement without clear episodic accelerations. The velocity of the limestone block is just above 2 mm/yr. The occurrence of gravity-induced joints indicates that the movement has an orientation towards 333° of azimuth on average, conditioned by the landscape around Chgega. These results were obtained through the analysis of a 3D model and a high-resolution orthoimage created from photographs acquired by an Uncrewed Aerial Vehicle (UAV). We may conclude that the landslide movement is determined by normal faults with directions N060°E and N140–150°E. This characterization of the Chgega landslide can serve as the basis for future studies about the origin of this slope movement. Furthermore, the data provided here may support the recognition of Chgega as a singular geological point that deserves to be declared a geosite.

Reads? 0 Downloads? 0 Abstract Cite All recommendations 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 up to 2 cm/yr 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 higher rate, up to 26 cm/yr during the last 14 years, due to compaction of a slag heap located within the foot of the landslide. 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.

Reads? 0 Downloads? 0 Abstract Cite All recommendations The tropical Northern Andes of Colombia are one the world's most biodiverse places, offering an ideal location for unraveling the linkages between the geodynamic forces that build topography and the evolution of the biota that inhabit it. In this study, we utilize geomorphic analysis to characterize the topography of the Western and Central Cordilleras of the Northern Andes. We supplement our topographic analysis with erosion rate estimates based on gauged suspended sediment loads and river incision rates from volcanic sequences. In the northern Central Cordillera, an elevated low-relief surface (2,500m in elevation, ~40x110 km in size) with quasi-uniform lithology and surrounded by knickpoints, indicates a recent increase in rock and surface uplift rate. Whereas the southern segment of the Central Cordillera shows substantially higher local relief and mostly well graded river profiles consistent with longer term uplift-rate stability. We also identify several areas of major drainage reorganization, including captures and divide migrations that are supported by our erosion and incision rate estimates. These changes in the topography coincide with the proposed location of a slab tear and flat slab subduction under the northern Central Cordillera, as well as with a major transition in the channel slope of the Cauca River. We identify slab flattening as the most likely cause of strong and recent uplift in the Northern Andes leading to ~2 km of surface uplift since 8-4 Ma. Large scale drainage reorganization of major rivers is probably mainly driven by changes in upper plate deformation in relation to development of the flat slab subduction geometry; however, other factors such as climate and emplacement of volcanic rocks likely play secondary roles in this process. Several isolated biologic observations above the area of slab flattening suggest that surface uplift isolated former lowland species on the high elevation plateaus, and drainage reorganization may have influenced the distribution of aquatic species.

Reads? 0 Downloads? 0 Abstract Cite All recommendations The European Space Agency’s Geohazard Exploitation Platform (GEP) (https://geohazards-tep.eu/#!) is a web-based platform through users can perform independent analysis by exploiting satellite data. This platform hosts several thematic apps that allow to identify, monitor and asses hazard related to geological processes such as volcanism, land subsidence or landslides. The Sentinel-1 CNR-IREA SBAS service is one of these thematic apps that consists on a Differential SAR Interferometry (DInSAR) processing chain for the generation of Earth deformation time series and mean velocity maps of surface ground displacement. In the last decades, DInSAR techniques have proved to be powerful tools to detect and monitor active processes related to geological ground instability issues. In this context, the Sentinel-1 GEP service seems to be a promising way to perform independent and high temporal resolution DInSAR analysis from any part of the world in just 24 hours. At present time, GEP continues being fine-tuned and users are working to validate the obtained results by comparing them with other data. In this way, it is possible not only to evaluate the advantages and limitations of the platform and but also to acquire new information about geological active processes around the world. In this work, we present an overview of different locations in the Mediterranean Basin and northwestern South America where we are accounted for previous knowledge of active landslide activity. Where there was previous InSAR analysis, we compared recent InSAR velocity maps with displacement rates that we obtained by the Sentinel-1 CNR-IREA SBAS tool to check their reliability. Moreover, we explored areas with no previous monitoring information but field evidence of ground instability. Beyond this, we considered this service as a successful tool to perform preliminary analyses of Sentinel-1 images in non-investigated areas to spot hazards and to delimit zones for performing detailed investigations. Additionally, some other unsatisfactory results allowed us to draw conclusions about technical constrains of the GEP tool and further asses its usefulness. ?

Reads? 0 Downloads? 0 Abstract Cite All recommendations The Camorro Fault is located at the foot of the northern slope of a limestone karstic massif that is called ‘Sierra de Las Chimeneas’, in the central sector of the Betic Cordillera (Southern Spain). The fault shows a well-marked surface expression. It is a 6 km-length strike-slip with extensional component fault that forms part of the Torcal Shear Zone. This fault can be continued 7 km eastward along the foot of northern slope of the ‘Torcal de Antequera’ (Málaga), World Heritage Site since 2016. The Camorro fault plane is well-exposed in some sectors while in others, the fault plane has been either affected by karstification processes or partially covered by talus deposits. One of the most characteristic geomorphological features of the ‘Sierra de Las Chimeneas’ area is an impressive rock avalanche deposit, covering an area of 2.2 km 2 and for which we estimated a volume of 0.48 Hm 3 . Given the characteristics of the rock avalanche deposit, we consider that it could be triggered by an earthquake on the Camorro Fault. This hypothesis is supported by other investigations that have already referred to quaternary paleoseismicity in this area. Previous archaeological research revealed a period of human occupation in a cave (‘Cueva del Toro’) located in the ‘Torcal de Antequera’ that point out evidences about the occurrence of a cataclysm in the late Copper Age (about 5000 years ago). Other studies have also suggested a possible connection between seismic events and megalith-building near Antequera. Beyond this, an archaeoseismic analysis in the megalithic site of Antequera (also World Heritage Site since 2016) found deformation structures probably linked to oscillations between the megalith orthostats during an earthquake. According to all of mentioned research, the Camorro Fault could be a good candidate to account for such prehistoric earthquake. Further geochronological work remains to be done, specially focused on dating (e.g. by cosmogenic isotopes) the fault scarp of the Camorro Fault and the associated rock avalanche deposits. If cosmogenic and archaeological dates coincide, we could attribute all the mentioned observations to an earthquake of severe magnitude in an area where the population ignore that hazard. Thus, we could contribute not only to the history of human occupation of the World Heritage Site but also providing insights into the earthquake recurrence and seismic hazard of the region.

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.

Reads? 0 Downloads? 0 Abstract Cite All recommendations Two orthogonal extensional systems produced the extensional collapse of the Tell and Atlas thrust belts in northern Tunisia during the Late Miocene to Pliocene in a context of NW‐SE plate convergence between Africa and Eurasia. The older extensional system shows several Low‐Angle Normal Faults (LANF) and associated high‐angle faults with ENE‐directed transport that produced half‐grabens and hanging‐wall syncline basins during the late Tortonian to Messinian. The direction of extension swinged towards the SE during the Messinian‐Pliocene, cutting into, and tilting the previous detachments. Extension was accompanied by the extrusion of 8 Ma rhyodacites and Messinian basalts, together with the development of mineralized fault breccias. Plio‐Quaternary NW‐SE directed shortening formed inversion arrowhead structures, reverse faults, re‐folded extensional roll‐over anticlines and folded the LANFs. ENE‐directed extension is concomitant with the opening of the Tyrrhenian basin. We consequently think that both processes are related and that tearing of the Calabrian slab along the Northern Tunisia coast drove the ENE‐directed extension. Meanwhile, the SE‐directed extension that followed was probably related to SE‐directed peeling of the Tunisian continental lithospheric mantle during NW subduction of the Maghrebian margin. This extension propagated eastwards from the late Tortonian until the Pliocene following the SE migrating subduction front, and favoured by lateral slab tearing along the Tunisian Atlas dextral STEP boundary. This new hypothesis for the tectonic evolution of Northern Tunisia shows for the first time the importance of crustal extension in the denudation of the Tunisian Atlas and Tell foreland thrust belts and its relation to deep mantle tectonic mechanisms.

This paper presents the evaluation of a surface velocity map that is generated by this platform. The map was produced through an unsupervised Multi-temporal InSAR (MTI) analysis applying the Parallel-SBAS (P-SBAS) algorithm to 25 ENVISAT satellite images from the South of Spain that were acquired between 2003 and 2008. This analysis was carried out using a service implemented in the GEP called “SBAS InSAR”. Thanks to the map that was generated by the SBAS InSAR service, we identified processes not documented so far; provided new monitoring data in places affected by known ground instabilities; defined the area affected by these instabilities; and, studied a case where GEP could have been able to help in the forecast of a slope movement reactivation. This amply demonstrates the reliability and usefulness of the GEP, and shows how web-based platforms may enhance the capacity to identify, monitor, and assess hazards that are associated to geological processes.

This humid climate produces weathered bedrock prone to landsliding. Ash fall from explosive eruptions kills the vegetation cover and intensifies erosion processes. These eruptions, hydrothermal activity and associated earthquakes destabilize the slopes of river valleys, and even the volcanic edifices, producing landslides and large debris avalanches. All these processes mobilize an extra sediment input that is deposited in the piedmont lowlands forming the Santa Clara megafan. The megafans described in the literature mainly grow according to climatic fluctuations; however, sedimentation in the Santa Clara megafan is also controlled by endogenic processes with longer recurrence periods. Analysis of this megafan provides new insight into the origin and evolution of these landforms. In volcanic regions, active volcanism should be considered when investigating the formation of some megafans. ACS Style Jorge Pedro Galve; Guillermo E. Alvarado; José Vicente Pérez-Pe?a; Mauricio M.

Reads? 0 Downloads? 0 Abstract Cite All recommendations Bilogora Mt. area is a transpressional structure located in the NE of Croatia, linked with the tectonic evolution of the Drava Depression. The structure formed during Pliocene and Quaternary due to inversion of NW-striking Drava Depression Boundary Fault, which originated as a normal fault and was reactivated as a dextral strike-slip fault. During Pliocene and Quaternary time, Bilogora Mt. area underwent more of 400 m of differential uplift, while still ongoing tectonic deformation is documented by historical and instrumental seismicity (3.5 ≤ ML ≤ 5.6). In this geomorphic study, the recent deformation in the Bilogora Mt. area, although obscured by landscape evolution variables, was assessed using DEM-based landscape morphometry and set of morphometric indexes. Local relief and slope angle variability distributions were combined with morphometric indexes computed at the scale of the drainage basin. We analyzed hypsometric curves with hypsometric integral (HI), basin asymmetry (AF) and parameters of longitudinal stream profiles (Cf, Cmax, Δl/L, θ and ksn). Analyzed morphometric parameters were combined into a cumulative index of relative tectonic activity (RTA). This index summarizes drainage basin response to the possible recent tectonic activity. Results suggest that most of the tectonic activity is probably located along the NE front of the Bilogora Mt. area, in its NW and central part. This activity could be likely related to recent tectonic activity along the Kalnik Mt. Fault zone and Drava Depression Boundary Fault zones, respectively. A subordinate area characterized by recent tectonic activity could be suggested within southernmost part of study area. Quaternary activity in this area is probably related to NE-striking faults in vicinity of the town Daruvar that continue towards the northeast into the study area. Though methodology presented here represents a good reconnaissance tool of possible ongoing deformation, this study will be followed by detailed fieldwork and paleoseismological investigations at the identified locations.

The qualitative and quantitative analysis is based on filtered topography, local relief, swath-profile analysis, anomalies on stream orientation, bulk erosion volume, hypsometry, and steepness index (k(sn)). All these parameters are intimately linked to river incision and development of drainage pattern, having been calculated to assess the role of folding and faulting on the evolution of the Sierra Nevada. Moreover, uplift rates in the core of the Sierra Nevada have been deduced from an extrapolation of the position of Late Tortonian to Pliocene coastline deposits. These data have been compared to apatite (U-Th)/He, fission-track and Be-10 cosmogenic data from SE Spain in order to evaluate the consistency among uplift, thermal histories and denudation rates. Our preferred tectonic scenario is one that favors fast exhumation of the western Sierra Nevada in a NW SE overall compressive setting produced by the convergence between the Nubia and Africa plates. Sub-perpendicular to this compression, a westward 4 mm/year extensional hanging-wall displacement promotes uplift and unroofing of the western part of Sierra Nevada.Spanish Ministry of Science and Innovation CGL-2011-2992 ACS Style J.M.

Reads? 0 Downloads? 0 Abstract Cite All recommendations In the present work, we show the case of Marina del Este resort, located in the southern Mediterranean coast of Spain (Costa del Sol). A medium-scale landslide has been recognized when the area was virgin. In 1977 started the initial works for urbanizing the area; later, buildings and facilities expanded uphill covering the landslide body. This case is characterized by a long history of corrective drainage and mitigate measures without success. An analysis of the landslide activity has been carried out by applying different approaches and based on the combination of the following: (1) geomorphological analysis, (2) PSInSAR technique application (ENVISAT 2003–2009), (3) an assessment of building and infrastructure damages, (4) rainfall time series analysis and (5) ground monitoring (2010–2011) data interpretation. Results show that, from 2003 to 2009, the landslide was active with velocities ranging from 5 to 15 mm/year. During the exceptional rainy period in winter 2009–2010, the movement velocity increased about ten times (velocities ranging from 40 to 90 mm/year) causing widespread damages in the resort. Buildings with high degree of damage are located at the toe of the landslide, close to the marina, where some dwellings have been evacuated. Marina del Este is a good example to show that landslides on coastal and steep slope areas are very vulnerable to reactivations and require thorough studies before any anthropic modification.

Reads? 0 Downloads? 0 Abstract Cite All recommendations A geomorphologic description of the Dúdar landslide (Granada, S Spain) has been carried out using a high-resolution digital elevation model derived from LIDAR (Light Detection and Ranging) data. We have analysed the significant changes that the landslide caused in the drainage system of the Aguas Blancas and Darro rivers, which in turn are the consequence of the tectonic activity of the north-eastern border of the Granada Basin. These modifications comprise river diversions and active incision within the body of the landslide, making it susceptible to future reactivations. A stability back-analysis of the landslide has been performed to identify the mechanism of failure and the most-likely triggering factors. This analysis shows that a low-to-moderate magnitude earthquake (Mw 5.0–6.5) related to the active faults in the Granada Basin seems to be the main triggering factor of the Dúdar landslide.
