Summary: Rainfall-triggered landslides can cause devastating damage and loss of life. NASA's global landslide catalog (GLC) compiles a record of such events from media reports, academic articles, and existing databases. The database includes various types of mass movement events triggered by rainfall and covers the period from 2007 to 2018. The evaluation of the GLC reveals global patterns in landslide reporting, including spatial and temporal distribution and comparisons with other inventories.

Summary: Understanding the relationship between rainfall events and landslides is crucial for geomorphological research and hazard planning. This study combines landslide inventories and rainfall estimates to analyze the factors influencing landslide susceptibility. The results show that land cover and slope have a greater influence on landslide susceptibility compared to rainfall intensity. Additionally, the study reveals that landslide density increases significantly with higher rainfall intensities.

Summary: The Indian Himalayan region is prone to landslides due to its complex geology, rugged topography, steep slopes, seismic activity, and heavy rainfall. Landslide susceptibility mapping is an effective solution for estimating vulnerability and determining potential consequences. This paper reviews 144 research articles published from 2010 to 2020 to understand the recent trends, techniques, and practices in landslide susceptibility zoning in the region. The review provides valuable insights for global practitioners and serves as a relevant database for scientists and researchers in the field of landslides, particularly in the Himalayan region.

Summary: This study analyzed landslide hazard, vulnerability, and risk in Costa Rica using the DesInventar disaster database and generalized linear models. The results showed that terrain, precipitation curves, and earthquakes were the main factors contributing to landslide hazard, while population, municipality area, and the Social Development Index were key variables affecting vulnerability. The multiplication of alternative landslide hazard and vulnerability indexes produced the risk index, indicating higher risk values in certain large and rural municipalities as well as densely populated urban units.

Summary: Understanding the spatial distribution regularity of coseismic landslides is crucial for mitigating future earthquakes. Through analyzing the distribution of landslides in the Ludian earthquake, the controlling factors were revealed. The slope gradient and the distance to the coseismic fault were identified as the two most important factors in determining the spatial distribution of coseismic disasters.

Summary: This study presents a predictive methodology for regional earthquake-induced landslides using a pseudo-three-dimensional (pseudo-3D) procedure implemented on a digital elevation model (DEM). The methodology calculates seismic displacement for each grid cell in the DEM to predict the location and size of landslides. The results highlight the role of seismic displacement models in landslide prediction and the impact of strength parameters.

Summary: This study presents a novel methodology integrating machine learning algorithms to assess landslide risk for slow-moving mass movements. By analyzing InSAR data, it identifies fifteen slow-moving phenomena traceable since 1955, with seven currently active landslides characterized by seasonal velocity patterns. This new methodology offers a different landslide risk scenario compared to existing official documents and provides insights on developing landslide risk management strategies worldwide.

Summary: This study examines the size distributions of rainfall-triggered shallow landslides in different landscapes, finding that similarities in size distributions may be associated with topography, mechanical soil strength controls, and spatial variability of hillslope strength. The research highlights the importance of constraining the spatial variability in material strength properties of hillslopes to understand the size distributions of landslides.

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: Landslide volume is closely associated with landslide mobility and damage, but direct measurement on-site is challenging. This study uses high-resolution LiDAR-derived digital terrain models to interpret the volumes of 1326 shallow landslides in Hong Kong. New models are proposed to estimate the volumes of small-scale shallow landslides accurately, enhancing landslide risk assessment and management.

Summary: Small glaciers in temperate mountain regions have experienced significant reduction and unprecedented melt rates in recent years. Some glaciers have transitioned from clean ice to debris-covered or even rock glaciers. This study examines the surface elevation change of the Popera Alto glacier in the Sesto Dolomites using LiDAR and Structure from Motion surveys, and analyzes its evolution in terms of surface cover and geomorphic processes. The glacier has lost an average of 0.35 m water equivalent per year over the past 16 years, with active modification of its surface cover by geomorphic processes. The role of debris and local topography feedback has allowed the resilience of the glacier, leading to a marked difference between the current environmental equilibrium line altitude (envELA) and the effective ELA (effELA) of the glacier.

Summary: In this study, we investigated a large slow-moving landslide in Northern Pakistan, using Interferometric Synthetic Aperture Radar (InSAR) analysis. Our results showed that the crown of the landslide is moving faster than the surrounding regions, while the footslope experienced high deformations. We discussed the possible roles of meteorologic and anthropogenic factors in causing these deformations.

Summary: The Yarlung River's drainage divide is primarily moving north due to variations in precipitation across the Himalayas. The Gangdese drainage divide shows predominantly northward and southward migration, controlled by base-level rise and downstream influences. The presence of north-trending rifts separates the drainage divides into five zones, each with a distinct migration pattern.

Surfaces of limestone boulders dating back to the Pleistocene era were found, and the ages of the hillslope armor increased with distance from the limestone bench. The estimated rate of lateral retreat in this landscape is 0.02 mm/yr.

Summary: The study investigates the relationship between glacial dynamics and lake sedimentation during the mid-Holocene climate variability in the Southern Zanskar ranges. It utilizes geomorphological disposition, elemental geochemistry, and optical chronology of relict lake sediment to reconstruct the pattern of minor glacier responses to climate variability. The results indicate six centennial to millennial-scale climatic phases, with warmer phases represented by decreased mineralogical fine grain flux and increased coarse grain flux. The study highlights the potential of relict lake sediment and para/peri-glacial landforms in understanding glacial dynamics and climate change during the Holocene.

Summary: Granule ripples are aeolian landforms armored against erosion by coarse grains. This study investigates their seasonal morphological evolution and migration in the Sanlongsha Dune Field. The findings show that wind events, especially those exceeding the threshold velocities of coarse grains, significantly influence the morphodynamics of granule ripples. The study highlights the importance of considering the reptation and saltation of coarse grains in future research on granule ripples.
