Summary: This study proposed an approach for the preliminary risk assessment of slopes with potential for large volume failure. The framework considers risk as a combination of landslide hazard, exposure, and vulnerability, classifying hazard level based on susceptibility and activity. Empirical relations were established using regression to determine landslide source area, volume, and friction coefficient, with the end product being potential risks classified into five levels. The study demonstrates the proposed approach's applicability in southern Taiwan for evaluating and ranking the risk level of slopes prior to risk management-related decision-making.

Summary: This study aims to develop a landslide hazard map and perform kinetic slope instability analysis in the Dasu dam site and its reservoir area in the Kohistan District. The use of GIS and remote sensing tools allowed for the creation of a landslide inventory map, which could help with risk assessment and mitigation in the future. The study also conducted field visits and scanline surveys to validate and evaluate slope instability issues. The overall efficiency of this work was determined to be 85%, indicating the reliability and effectiveness of the tools used.

Summary: Disturbed landscapes caused by shallow landslides present residual risks such as re-occurrence of landslides due to residual soils and multiple hazards associated with river blocking or landslide damming. However, few studies have investigated these residual risks, and no methodology has been established for assessing them. This study combined portable cone penetration test (PCPT) and electrical resistivity tomography (ERT) to investigate the post-event risks of a landslide scar caused by the 2018 Hokkaido Eastern Iburi earthquake (HEIE) in Japan. The findings imply a widespread risk of re-occurrence of shallow landslides over a 20 km x 20 km area.

Summary: This paper investigates the influence of rainstorm conditions on the stability of layered soil slopes through physical model tests and numerical simulation. The results show that the layered structure and inclination affect the rainwater infiltration and stability of the slopes. Different inclinations greatly influence the safety factors, with downdip slopes being more susceptible to landslides. The results provide a theoretical basis for designing a stratified soil slope management plan.

Summary: This study examines the technical summary and forensic analysis of a landslide that led to the collapse of the ski-jumping complex in Erzurum in 2014. Various perspectives including geological, geophysical and geotechnical are considered to illuminate the true causes of this engineering failure. The study aims to provide engineers and public administrators with an example of the importance of considering critical ground conditions and well-established design principles in civil engineering projects.

Summary: The last three decades have seen significant advances in data-driven models for landslide prediction, particularly in estimating landslide susceptibility. However, an equally important piece of information is the potential landslide area once landslides occur. This study fills this gap by using a Generalized Additive Model to predict the topographically-corrected landslide area. The model's performance was evaluated using cross-validation and showed strong correlation and consistent patterns.

Summary: This paper focuses on the threat of water damage geological disasters brought by the complex terrain along the long-distance natural gas pipeline. A meteorological early warning model for water damage geological disasters in mountainous areas based on slope units has been constructed to improve the prediction accuracy of such disasters and timely early warning and forecasting. The proposed model can provide a basis for accurate disaster prevention in the research area and areas with similar geological environments.

Summary: The study developed a new neural network-based prediction model for Newmark's sliding block displacements, utilizing multiple parameters to predict slope displacement. The model accurately captured displacement features and exhibited agreement with existing relations in literature. The applicability of the new model in estimating slope displacement hazard was demonstrated in a representative scenario in the Himalayan region.

Summary: Geological disaster risk assessment can quantitatively assess the risk of disasters to hazard-bearing bodies. Visualizing the risk of geological disasters can provide scientific references for regional engineering construction, urban planning, and disaster prevention and mitigation. This paper introduces a landslide hazard assessment model based on a multiclass support vector machine (SVM) and combines the analytic hierarchy process (AHP) and entropy method to construct a landslide vulnerability assessment model that considers subjective and objective weights. The experimental results verify the feasibility and effectiveness of the proposed model and provide important decision support for decision makers in Xianyang City.

Summary: A coupled model of Peridynamics into the mesh-free method was used to simulate the impacting collapse of a granular column with various suspended heights. The simulated free surface profiles were in good agreement with experimental measurements, and the numerical model was validated by simulating the granular column collapse and comparing the kinetic energy and potential energy with DEM simulation results. The analysis revealed that the suspended height in the impacting collapse of the granular column significantly affects energy dissipation.
