Summary: The Jiaju ancient landslide is a massive landslide located in the eastern Tibetan Plateau, with a volume of approximately 7.04 x 10(8) m(3). The secondary sliding bodies of the Jiaju ancient landslide are undergoing significantly different creep-sliding deformation due to regional neotectonic movement, heavy rainfall, river erosion, and lithology, which can cause extensive damage to surrounding villages, roads, and rivers. By utilizing the SBAS-InSAR method, Sentinel-1A data, remote sensing, and field surveys, this study obtained the deformation characteristics and deformation rate of the Jiaju ancient landslide. The maximum deformation rate of the Jiaju ancient landslide is significant, and certain sliding bodies are experiencing accelerative deformation and are at a warning level, especially under heavy rainfall, which can accelerate landslide deformation and trigger reactivation.

Summary: Delivery of large volumes of sediment by debris flows can cause a hazardous chain reaction in rivers. Artificial intervention measures, such as dredging, rechanneling, and embankment construction, have shown to be effective in halting this cascading process of natural hazards.

Summary: This study focuses on large-scale landslides along rivers in mountain regions, finding that the formation of riverbank landslides is closely related to river valley evolution, caused by regional tectonics, river valley cutting, and water infiltration. The investigation reveals that weak interlayers play a key role in the formation of multi-level landslides.

Summary: In this study, evidence of an ancient, large-scale river-damming landslide in the southeastern Tibetan Plateau, China, was revealed using various methods. The landslide had a estimated volume of 3.5 x 10(7) m(3) and formed a dam over 170 m in height. Lacustrine sediments were found on both banks upstream of the landslide dam, indicating blockage of the Jinsha River. The landslide was likely triggered by a strong earthquake related to activity on the Xiongsong-Suwalong fault in the Late Holocene.

Summary: It has been discovered that there is an ancient landslide called the Huang-Cao-Ping landslide in the Sichuan province of China, which was triggered by a strong earthquake and blocked the Baqu River, forming a landslide lake that was later breached. The study results are expected to be significant for the reconstruction of regional tectonic activity history and for the study of similar rockslides.

Summary: This study introduces a new type of multi-hazard chain in China, involving debris flow blocking a river, the formation of a barrier dam and lake, lake outburst, revival of an ancient landslide, and flood-induced debris flow. The research shows that the risk of this multi-hazard chain may increase in the future, and suggests using rigid dams and flexible barriers as countermeasures.

Summary: The study investigated an ancient river-damming landslide in the upper Jinsha River of the southeastern Tibetan Plateau, and found that the landslide was most likely triggered by buckling of rock slabs. OSL dating indicated that the lacustrine sediments formed by the landslide have an age of approximately 2.6 ka, and gravitational deformations are still affecting the hillslope.

Summary: This paper investigates the impact of river erosion on landslides in the Polish Outer Carpathians. The study found that landslides remain active during floods, with colluvial material continuously removed between flood events. The amount of material carried away by streams during floods accounted for a significant portion of the total material removed during the study period.

Summary: This study proposes a comprehensive flood risk assessment method for the Dadu River basin in southwestern China. The results show that the southern part of the basin is prone to frequent floods, with higher vulnerability levels mainly concentrated in the downstream. The high and very high risk zones mainly concentrate in the southern basin.

Summary: This study focused on two rockslides that occurred on October 10th and November 3rd, 2018 in Baige Village, Jiangda County, Tibetan Autonomous Region, China. The research aimed to clarify the geological conditions of the slides and understand the reasons behind the occurrences. The analysis revealed that the landslides were a result of geological structures and river erosion, with estimated speeds reaching up to 67 m/s.

Summary: The winding Dasha River section of the Central Cross Island Highway in Taiwan has faced maintenance challenges due to landslide-induced problems. Variations in engineering characteristics of rock masses have led to instability of nearby slopes, requiring effective measures to prevent landslides.
