Summary: From August 31 to September 2, 2014, a 50-year heavy rainstorm caused a series of large-scale landslides in the Northeastern Chongqing area, China. The distribution of these landslides coincided with variations in rainfall intensity, with a threshold of 200 mm. The leading causes of these landslides are topographical, geological, geotechnical, and rainfall conditions. Future disaster prevention and mitigation should take these findings into consideration.

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: It is recognized that post-seismic mass movements usually occur in the first few years after an earthquake. However, a major debris flow occurred in Wenchuan County in 2019, 11 years after the 2008 Wenchuan earthquake, indicating a different temporal evolution pattern. The investigation results show that active landslides mainly occurred in high-elevation areas without vegetation cover, and the debris flows were mainly initiated by run-off erosion of debris in steep channels. Additionally, more debris flows occurred in the northern part of the study area, where the relative annual rainfall and coseismic landslide density were low.

Summary: This paper presents a novel method for predicting the time and path of landslides using remote sensing data and a new technique. By analyzing ground deformation trends and displacement time series data, the time and flow path of landslides can be predicted. This study is significant for improving the accuracy of landslide early warning in hilly areas.

Summary: The use of Remotely Piloted Aircraft Systems (RPAS) has significantly improved the characterization and monitoring of landslides in the past decade. RPAS is particularly effective in studying areas prone to geohazards, providing high-resolution orthophotos and digital surface models for better understanding and mapping of affected areas.

Summary: The landslide-induced debris flow in Wangcang County, Sichuan Province on August 14, 2020, resulted in three deaths and two destroyed houses. Factors such as continuous rainfall, interbedded marlstone with structural planes, and changes in slope gradient contributed to the disaster. The study findings may serve as a reference for future research on geohazard chains.

Summary: This study examines the factors influencing the travel distances of landslides in Hong Kong, finding a close relationship between horizontal travel distances and fall heights. Furthermore, it is noted that the travel distances of channelized debris flows are significantly enlarged on colluvium lands due to the entrainment of loose materials.

Summary: Determining how debris flows erode and deposit material is challenging in natural settings. This study uses high-resolution lidar data to evaluate the growth and decay of debris flows triggered by rainfall in Polk County, North Carolina. The analysis reveals three discrete phases of debris flow evolution and identifies a power law relationship between flow distance and the growth rate of debris flow.

Summary: High discharge debris flows in mountainous and volcanic areas pose significant threats to populations and infrastructures. Modeling these events is challenging due to their complexity and lack of data. This study successfully models a rock avalanche and subsequent remobilization of deposits as a high discharge debris flow using field data and realistic simulation scenarios. The results are consistent with observed data.

Summary: The study found that channel-head migration caused by shallow landslides during storm events can have an impact on debris flows. In the study areas, areas with larger pre-event channel heads are more prone to shallow landslides.

Summary: The study aimed to investigate the formation and propagation processes of landslide-generated debris flows in vegetated areas by considering the effects of vegetation. The proposed comprehensive model effectively described the behaviors of each stage in the process and analyzed the roles of vegetation in different stages.

Summary: This study interprets and reproduces the geomorphological and volumetric characteristics of a catastrophic landslide in Chamoli, India, using satellite images and a cell-based analysis program. The results reveal the dynamics of the disaster chain and peak flow discharge of the debris flood in high mountain areas, serving as a basis for understanding such events.

Summary: In early December 2020, an extreme weather event consisting of an atmospheric river and rain-on-snow caused flooding and mass movement in Haines, Alaska. The event, which was considered a one-in-500-year occurrence, triggered a devastating landslide that resulted in casualties and property damage. The study highlights the importance of identifying pre-existing landslide features and potential source areas for future landslides. With projections of increased similar events in Southeast Alaska due to warmer and wetter winters, the development of an AR scale combined with geological information is recommended for better warning systems.

Summary: Glacial debris flows are a common catastrophic hazard caused by glacier recession and permafrost thawing. This study focuses on a typical glacial debris flow in southeast Tibet, China, and reveals its initiation mechanisms and dynamics. The findings provide a scientific basis for understanding and minimizing the adverse impact of this hazard on key infrastructures.
