Summary: A study conducted on the High City of Antananarivo, an important cultural heritage site in Madagascar, assessed the landslide hazard in the area. The study found that slope, lithology, creek erosion, and human activities are the main factors affecting landslides, with heavy rainfall being the primary trigger. The study's findings provide fundamental land use management tools for the protection and conservation of the High City.

Summary: This article investigated the causes of a landslide that occurred in Tullu Gola Peasant Association, West Arsi Zone, Oromia, Ethiopia, using geotechnical conditions and geophysical techniques. The study found that the landslide was caused by a combination of circumstances, including soil type, high rainfall, deforestation, and nearby streams. Corrective measures to mitigate the risk of landslides, such as slope drainage, soil grouting, tree planting, and gabion construction, were suggested.

Summary: This study introduces a framework for temporal and spatial rockfall early warning based on microseismic monitoring. By detecting and classifying rockfall events, the method provides warnings based on accumulated energy, as demonstrated by successfully predicting a large rockfall 3 minutes in advance in an experiment.

Summary: This article presents a case study of a landslide near a tunnel entrance in China, where the landslide debris was successfully intercepted by a flexible barrier originally installed to stop rockfalls. Through field investigation and numerical analysis, it was found that the flexible barrier had sufficient energy capacity to withstand the impact of the landslide, and it effectively dissipated a significant portion of the energy.

Summary: The risk assessment of geological hazards is crucial for disaster prevention and mitigation, providing important references for local infrastructure construction, tourism development, urban planning, and regional economic development. The evaluation results based on the hierarchical entropy variable weight method are more accurate, with an accuracy rate of 67%.

Summary: The study focused on a 200 km long section of the Karakoram Highway, from Besham to Chilas, where landslides were found to be frequent, often triggered by torrential rain during Monsoon and Westerlies, leading to highway blockades. Remote sensing techniques were used to identify potential hazardous sites and assess risks, resulting in the classification of four zones with different risk levels based on normalized scores from each site.

Summary: This article examines the design of steel baffles embedded in soil for containing fallen boulders. Analytical solutions based on a standardized static model are presented, and dynamic testing and numerical simulations are conducted to verify the accuracy of the proposed model. The study finds that the required depth of embedment for long pile behavior is scale-dependent, contrary to commonly held notions. The proposed analytical model is suitable for steel baffle design, leading to significant cost savings and acceptable performance.

Summary: In steep, mountainous terrain, protection forests are crucial in preventing rockfall risks. A tool called RockForNET (RFN) can assess the remaining rockfall hazard by modeling the protective effect of forests using the energy line principle. This study aimed to reconstruct the energy line angle (ELA) and initial fall heights of rockfall deposits on forested slopes in Switzerland, and to enhance RFN by estimating trajectory-specific ELAs and better initial fall height values. The results showed that using transect-specific ELAs and more specific initial fall height values significantly improved the prediction of a forest's protective capacity, especially for block volumes between 0.2 and 1 m3. Additionally, there was a strong correlation between retro-calculated ELAs and the normalized area below the rockfall trajectories, suggesting that the normalized area is a promising method for deriving trajectory-specific ELAs.

Summary: This paper investigates the rockfall hazards on high slopes post-landslide, proposing a comprehensive assessment strategy based on terrestrial laser scanning. By simulating and correcting using 3D probabilistic models, the study reveals that rockfalls pose significant threats to emergency rescue personnel and railway safety.

Summary: The geological hazard of landslide or debris flow is a significant cause of mortality. Existing segmentation methods for natural imagery are not effective for irregular contour and arbitrary scope of landslides and debris flow. Hence, a novel segmentation method called correlation weighted network (CoWNet) is proposed to precisely segment the hazards.

Summary: On the 26th of November 2022, heavy rainfall triggered diffuse landslides in the Northern sector of Ischia. This study investigated the characteristics of a debris flow that occurred in Casamicciola Terme Municipality. The debris flow originated from the Northern slope of Mt. Epomeo and caused significant damage to buildings, resulting in casualties, injuries, displacement, and severe damage to the road network. The study used field investigations, environmental data, and numerical models to assess the event and emphasized the need for careful monitoring and risk management activities in the future.

Summary: The study focused on rockfall stability analysis and developing an improved rockfall hazard matrix chart. Structural mapping and RocFall software were used to identify parameters influencing rockfall occurrence and monitor kinetic energy variations. The presence of joints and bedding planes weakened the rock mass along R518 road, leading to potential rockfall. Simulations with RocFall highlighted the impact of slope height, vegetation density, slope angle, and rock velocity on the extent of rock fragmentation reach. An improved rockfall hazard rating chart was proposed based on empirical and numerical findings for assessing rockfall hazard levels along highways and roads.
