Summary: Determining the age of landslide events is crucial for assessing landslide risk, triggers, and predicting future occurrences. Dendrogeomorphic analysis is currently the most accurate method for dating historical landslides. This study utilizes a groundbreaking methodological approach by analyzing the anatomical growth response of trees to landslide movements. The results reveal different responses in trees growing in different morphological zones of the landslide, providing important recommendations for future landslide research and improving the accuracy of landslide risk assessment.

Summary: This study reconstructed the timeline of past anthropogenic landslide events for the first time using the anatomical responses of Betula pendula trees. By combining tree-ring anatomy, geophysical surveys, geomorphic mapping, grain size analysis, and meteorological data, the study conducted a detailed multidisciplinary analysis of selected anthropogenic landslides, detecting two types of landslides and discussing the impact of spoil heap material grain size on their development. The study also found evidence of extreme short-duration high-intensity rainfall preceding a drought period triggering all dated landslide events, demonstrating the potential of innovative dendrogeomorphic methods for landslide analysis.

Summary: This study proposes a novel method that improves the performance of landslide susceptibility (LS) models using the TrAdaBoost transfer learning algorithm. The method transfers useful knowledge from one landslide inventory to another, reducing the effort required to collect landslide data. The results demonstrate that when using the TrAdaBoost model with the landslide inventory from the source area, the performance of LS models is significantly improved.

Summary: In landslide susceptibility mapping (LSM), the expression of landslide boundaries and spatial shapes as points or circles instead of accurate polygons can lead to differences in the predicted landslide susceptibility indexes (LSIs) and introduce uncertainties into the LSM. This study compared the uncertainties of LSM modeling using different representations of landslide boundaries and spatial shapes, and found that using polygonal surfaces to represent the landslide boundaries can significantly improve the accuracy of LSM compared to using points and circles. The results also showed that polygon-based models have higher LSM accuracy compared to point- and circle-based models, and the overall accuracy of the random forest (RF) model is superior to that of the support vector machine (SVM) model.

Summary: The study determined the age of the Mahu giant landslide, revealing that it was formed by two major events with error weighted mean ages. This provides a basis for understanding the causes of the landslide and suggests that regional fault activity and earthquake risk can be analyzed from the perspective of landslide science.

Summary: This study compared three models, frequency ratio, Shannon's entropy, and AHP, for landslide susceptibility mapping in Shimla district, India. The frequency ratio model showed the highest accuracy, followed by Shannon's entropy, and AHP had the lowest accuracy. The results can be used by engineers and planners for better landslide management in the study area.

Summary: Lichenometry, a dating method based on lichen growth rates, has been criticized for its reliability issues. Problems include difficulties in identifying the lichen species commonly used, variability in growth due to environmental factors, and uncertainty in colonization time on fresh rock surfaces. This paper suggests alternative dating methods and procedures to improve the reliability of lichenometry for dating rock surfaces.

Summary: The main driving factors of extensive landslide activities in the Three Gorges area of the Yangtze River in China include continuous river incisions, heavy precipitation events, reservoir water-level fluctuations, and changes in groundwater flow. Despite the ability to technically detect triggers for major landslide events, predicting and mitigating them remains challenging. Analysis of the Outang landslide reveals that it consists of four individual sliding bodies formed consecutively since 130 ka BP.

Summary: This study focused on landslide susceptibility zonation in Qilihe District, Lanzhou City, incorporating landslide classification and various influencing factors through a data-driven model. The results showed that the majority of landslide pixels were classified as high or very high susceptibility zones, with a satisfactory model accuracy. Consideration of landslide typology significantly improved the accuracy of the susceptibility assessment maps.

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: The study reveals a strong association between the mechanical response of a shear band in deep-seated landslides and the mineralogy and microstructure of clay minerals forming the shear band. The alignment and face-to-face contact of phyllosilicate grains within the shear band play a crucial role in altering the material's mechanical properties, increasing plasticity index, reducing porosity, and ultimately promoting slip of the overburden.

Summary: The stability and erosion of slopes are influenced by soil-vegetation-atmosphere interactions and thermo-hydro-mechanical slope conditions. Vegetation can enhance rainfall infiltration, decrease runoff, and reduce slope instability and surficial erosion. Additionally, vegetation can reduce solar radiation, heat flux, temperature fluctuations, and evaporation.
