“…The movements are currently active as the fresh cracks observed in the buildings and broken gypsum marks on fissures demonstrate ( Figure 4A). Fernández et al [31] measured the movements in this place analyzing ERS1/2 images with the SmallArea PSI approach [37]. Their data fit well with the measurements given by GEP although the time span is different ( Figure 5).…”

“…The high plains of the study area are intra-mountainous basins that are filled by Neogene sediments, surrounded by low-relief Mesozoic materials from the External Zone of the Betics. A great variety of mass movements have been described in these high plains [30], as well as documented human-induced subsidence [19,21,[31][32][33].…”

Abstract:The analysis of remote sensing data to assess geohazards is being improved by web-based platforms and collaborative projects, such as the Geohazard Exploitation Platform (GEP) of the European Space Agency (ESA). 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 technique has been mostly applied for monitoring tectonic motions (Kimura and Yamaguchi, 2000;Bürgmann et al, 2006;Delouis et al, 2002;Johanson and Bürgmann, 2005;Wright et al, 2004;Bürgmann et al, 2002). It has also been used successfully for surface effects of subsidence induced by natural causes or man made activities (Poland et al, 2006;Amelung et al, 1999;Tomas et al, 2005;Dixon et al, 2006;Fernandez et al, 2009). However, InSAR technique, for deformation monitoring, depends a lot on local conditions such as topography, vegetation, atmosphere as well as resolution of data.…”

Toppling failure of rock slopes is a complicated mode due to a combination of both continuous and discontinuous deformation, especially in dealing with anti-dip rock slopes. In this paper, a novel continuum-based discrete element method (CDEM), which is useful in modeling the entire progressive process from continuous to discontinuous deformation, is proposed to analyze the deformation characteristics, the failure mechanism and the evolution process of a large-scale open pit slope with a typical anti-dip structure. To simulate the slope deformation, the shear strength reduction method (SSR) is adopted to represent the strength degradation of rock mass in the deterioration process. The simulated results are validated using data obtained from a field investigation and continuous monitoring by employing an advanced remote sensing technique called ground-based interferometric synthetic aperture radar (GB-InSAR). To analyze the evolution trend of the anti-dip slope, the subsequent toppling failure mode is predicted using the validated CDEM models. Based on a case study of a slope at the Fushun open pit mine (in Fushun, China), the unique geological structure with various joints and discontinuities, groundwater, intense rainfall, and mining activities are identified as the main triggers for different failure stages. The comparison between the field data and the simulation shows that CDEM accurately depicts the rock deformation and the failure pattern of the studied slope. The proposed numerical modeling techniques can be used for predicting failures of other similar excavated rock slopes. The simulated evolution process and the recorded deformation patterns help engineers to gain a better understanding of rock mass movement of anti-dip slopes, and the presented methodology could be utilized for similar studies and engineering designs.
