Summary: This study explores the integration of artificial intelligence (AI) and empirical techniques for evaluating rock slope stability, using the Q(slope) system as a framework. By incorporating fuzzy set theory into the Q(slope) classification, a novel approach is proposed to effectively quantify and accommodate uncertainties in coastal regions. The preliminary tests conducted on slope instabilities within coastal zones indicate promising results, affirming the precision and dependability of the proposed AI-based approach. However, further validation efforts are required to establish the reliability and effectiveness of this innovative method across diverse scenarios.

Summary: The stability of rock slopes with weak planes was evaluated using empirical slope mass rating (SMR) and kinematic analysis, and a mechanical-based method was used to study the effects of weak plane orientations. The results showed that the SMR values and numerical safety factors exhibited similar trends, indicating the rationality of the approach. The determination of the lateral limit angle in kinematic analysis was found to be subjective, requiring consideration of actual conditions for accurate assessment.

Summary: This research focused on the Langjia landslide in Qinghai Province of China to explore the failure mechanism and mode of deep relaxation rockslide in cold and arid areas of the plateau. The main precondition for the landslide was found to be deep relaxation tension cracks, triggered by strong weathering and disintegration of argillaceous cemented conglomerate on the sliding surface. The influence of rainfall, snow melting, and temperature accelerated the development of cracks and weathering process, leading to the formation of a sliding surface of mud rock with gravel.

Summary: Cracks have a significant influence on slope stability, especially for slopes with soil strength governed by a linear criterion. This study analyzes rock slopes with cracks using a nonlinear rock model. The kinematic approach of limit analysis is used to consider open cracks and provide rigorous bounds to limit loads. The depth range of vertical cracks in the Hoek-Brown rock mass is derived for different crack boundary conditions. The presence of cracks reduces tensile stress but maintains compressive stress in rock slopes.

The methodology provides a powerful tool for understanding the local dynamics of DsGSDs in relation to strategic infrastructures and inhabited areas, aiding in infrastructure maintenance and territorial planning.

Summary: Measuring glacier elevation change is crucial for various purposes, such as estimating glacier mass balance, calibrating climate models, and assessing the impact of global warming. In this study, we explored the potential of clinometry as a technique to quantify glacier elevation changes. By analyzing shadow positions in monoscopic optical images, we were able to measure a glacier thinning rate of -1.9 +/- 1.7 ma(-1) between 2017 and 2021 for the Aletsch Glacier (Switzerland), consistent with previous observations.

Summary: The coastal region of southwest Saudi Arabia contains a thick sequence of Late Oligocene basalts in the Jizan Group. These basalts lack primary permeability but are cross-cut by fractures. The area is composed of half-grabens and exhibits a highly fractured nature. This makes it suitable for the injection and mineral carbonation of carbon dioxide from industrial sources.

Summary: In this study, the fault and fracture network of the Middle Triassic carbonate platform of the Lastoni di Formin in the Italian Dolomites was analyzed. The research findings indicate that the present fracture pattern is the result of differential compaction-induced deformation, and subsequent extensional and compressional tectonic events also affected the platform.

Summary: This work presents a methodology for assessing rockfall risk and creating a geodatabase of mitigation structures focused on small communities. Various techniques, such as digitization of archival sources, utilization of a historical landslide database, and UAV-LiDAR survey data, were employed to create a reliable and cost-effective state-of-the-art method. Additionally, a simple webGIS and a 3-D interactive view were developed to disseminate information about rockfall hazards and mitigation strategies.

Summary: A dedicated procedure has been implemented to explore the behavior and define the state of activity of 279 deep-seated gravitational slope deformations (DsGSDs) in the Aosta Valley Region. The procedure involves the use of Differential Interferometry Synthetic Aperture Radar (DInSAR) techniques to detect and identify Persistent Scatterers (PSs) and assess Sentinel-1 data coverage. Spatial analysis based on cluster and outlier identification is carried out to characterize the moving phenomena and their degree of variability in deformation rates. The methodology provides a valid instrument to remotely define the state of activity of these phenomena, which are often underestimated or neglected in risk management.
