Summary: The study analyzed rainfall data for 613 shallow landslides in South Korea from 1963 to 2018 to determine rainfall thresholds and investigate the influence of antecedent rainfall. The results suggest that the southern region of the Korean Peninsula is more susceptible to rainfall-induced landslides, and the effect of antecedent rainfall conditions should be further tested considering regional climate and local site conditions for a better understanding of landslide occurrence.

Summary: Several studies have found that existing empirical rainfall thresholds for landslide occurrence do not consider the morphological and hydrological conditions of the areas. Therefore, a software tool called DEWS is introduced for selecting representative rain gauges, which is a crucial step in defining empirical rainfall threshold models. DEWS employs four filters and requires three data inputs, and its reliability has been tested in South Korea.

Summary: Rainfall-induced shallow landslides often transform into flows, posing a severe hazard to infrastructure and human lives in mountainous areas worldwide. Back-analysis of previous events can inform risk assessment and the design of mitigation measures. However, conventional back-analysis exercises do not account for the occurrence of flows in sequences or surges, leading to potential inaccuracies in hazard assessment. In this paper, a novel time-resolving procedure is proposed to address this issue, which discretizes the event and tracks the post-failure behavior of each surge separately. The results of two case studies demonstrate that the time-resolving procedure can significantly impact the runout path, flooded area, and flow heights, highlighting the need for a review of historical cases and reassessment of current practices.

Summary: This study collected over 200 events described as debris flow in the Campania Region of Southern Italy between 1924 and 2020, classifying them as gravity processes or fluvial processes. The classification is essential for designing early warning systems and risk mitigation plans based on different rainfall events triggering the two phenomena. The research explored a large rainfall database to identify the time scales and seasonality of the rainfall events triggering the two classes of phenomena.

Summary: The study investigates the rainfall intensity anomalies associated with 10 hazardous rainfall events that triggered numerous landslides in Japan by using a standardized period of rainfall measurement in conjunction with the return level of rainfall intensity. Shallow-landslide-triggering rainfall events were divided into two types, while deep-seated landslides required over 1000 mm of precipitation to be triggered. Despite differences in the characteristics of the hyetographs among the landslide-triggering rainfall events, all the landslides could have been triggered when the mean rainfall intensity reached the 100-year rainfall level during the standardized period.

Summary: Typhoon Morakot had a serious impact on Taiwan, especially in terms of large-scale landslides (LSL). This study aimed to establish a specific relationship between LSL and triggering rainfall for future early warning predictions. By collecting various data, including satellite imagery, field investigation data, major event reports, and seismic data, the study analyzed rainfall/landslide depth and friction angle/slope through linear and non-linear regression analysis. The results showed that the non-linear regression analysis had a better correlation trend and could provide more conservative indicators for early warning management. Incorporating real-time rainfall forecasts, the study suggested that these indicators could be used to guide evacuation operations and improve response time.

Summary: Continuous and heavy rainfall in the Tianshui area triggered shallow loess landslides, with the fourth rainfall event showing the best prediction ability. The first two rainfall events only contributed to preparing for landslides in the later period. The combination of the fourth and third rainfall events determined the spatial distribution characteristics of the landslide.

Summary: Many landslides have occurred in Niigata, Japan, but the mechanisms behind different types of landslides occurring under similar conditions remain unclear. Through a study of a small landslide triggered by Typhoon Hagibis in 2019, researchers found that the behavior of landslide materials, such as shear strength and mobility, plays a crucial role in regulating different landsliding phenomena.

Summary: In shear tests under normal unloading conditions, marlstone with parallel fissures exhibited a tensile-shear failure mode, with tensile failure concentrated in the middle of both sides. The study also found that high shear stress had a greater effect on shear deformation than dilatancy deformation, while high normal stress had a greater inhibiting effect on dilatancy deformation than on shear deformation.

Summary: Scale effect has minor influence on the shear stress-strain relationship of soil-rock mixtures (SRM). The Mixing Method is suggested as the optimal scaling method for studying shear behaviors in SRM in laboratory conditions. Different scaling methods can lead to disparities in shear strength and other strength parameters, with normal pressure and stone content significantly affecting bulk shrinkage in SRM samples during shear.

Summary: This article investigates the temporal and spatial evolution process of overlying karst mountain instability caused by mining using the case of a mega landslide in Pusa, Nayong County, Guizhou Province, China on 8.28. The complete process of rock strata fracture and slope instability under both descending and ascending mining conditions is reproduced through similitude model experiments. The failure process of slope collapse controlled by deep and large karst fissures is summarized based on the key motion features of overburden deformation and fracture evolution. The change law of overburden pressure and displacement during the mining process is analyzed, and the failure mode of slope collapse is proposed.

Summary: This study investigated the effect of long-term freeze-thaw (F-T) cycles on the stability of heavy metal (HM)-contaminated soil treated by stabilization/solidification (S/S) technology. The results showed that the S/S technology transformed HMs into more stable forms, with different transformation efficiencies for each HM. The study also revealed the change trend of the contaminated soil under long-term F-T cycle and identified the critical point for pollution prevention and control, providing theoretical support for soil remediation projects.

Summary: Solidification/stabilization (S/S) is the predominant remediation technology for heavy metal contaminated soils. Freezing-thawing (F-T) cycles can deteriorate the effectiveness of S/S on lead-contaminated soils. Using different proportions of cement, lime, and fly ash as compound curing agents can improve the strength and chemical stability of treated soils. The results show that the duration of F-T changes the strength deterioration mechanism of cured lead-contaminated soils. Structural damage induced by prolonged F-T becomes the main influencing factor. Fly ash and cement help maintain the strength of treated soils under long-term F-T conditions. Lime is favored for lead stabilization. A higher proportion of lime and cement in the curing agent formulation reduces the risk of lead leaching.

Summary: Karst landforms are common in southwestern mountain areas in China, and the extensive underground mining activities often cause catastrophic collapses and landslides. This study aims to understand the development of karst fissures and the slope deformation process, especially in relation to collapse and landslide phenomena. Using the Pusa landslide as a geological prototype, the universal distinct element code (UDEC) was used to simulate the overall deformation of the mountain with extensive karst fissures during mining activities. The results showed that mining caused bending, subsidence, and even collapse of the roof above the goaf. Karst fissures played a crucial role in the deformation and stability of the slope, with the limit karst fracture depth determining whether the rock mass at the slope top toppled or slipped.
