Summary: This study used time-series InSAR analysis to investigate the kinematics and volume of landslide induced by rainfall in Danba County, Sichuan Province. The results showed that the 2020 rainstorm and abundant precipitation altered the long-term displacement trend of active landslides, and seasonal acceleration was related to concentrated rainfall.

Summary: Landslides and debris flows are common in the Zhouqu County in Gansu Province, China, due to river erosion, rainfall, and deforestation. Using remote sensing technology, distinct displacements were observed in the fractured fault zone, with temporal variations primarily influenced by seasonal rainfall.

Summary: This study investigates landslides triggered by earthquakes in a semi-arid region, finding that there are more limited-sized rockfalls near the epicenter and larger deep-seated landslides farther away, which is explained as an interaction between earthquake source properties and local geological conditions. The study also examines the kinematics of earthquakes-accelerated slow-moving ancient landslides.

Summary: Recent studies have shown that ancient landslides triggered by historical earthquakes are reactivated by fault activity and heavy rainfall. The deformation behavior of landslides is highly responsive to seasonal rainfall, with sliding movements accelerating sharply during the rainy season and decelerating during the dry season.

Summary: This research proposes an emergency assessment model for post-earthquake landslides using remote sensing technology and the Newmark physical mechanics assessment model. The model, called InSAR Data-Newmark Physical Fusion Driver Model (IDNPM), comprehensively considers the dynamic deformation of the ground surface and geological features. The results show that the IDNPM effectively reduces prediction errors and improves accuracy compared to the traditional Newmark model. The research findings provide valuable references for the development of post-earthquake landslide emergency prediction models.

Summary: This paper proposes a new method for landslide hazard assessment that combines the deformation rate results obtained by InSAR with conventional assessment results. By considering the deformation factor of the study area, the hazard assessment level is obtained. Through a case study, it is demonstrated that this method can achieve near-term hazard assessment and dynamic regional landslide hazard assessment.

Summary: This study investigates the effects of rainfall on the stability of a flysch slope and the reactivation of landslides. It highlights the crucial role of rainfall duration in landslide reactivation, as well as the significant correlation between antecedent rainfall and time to failure. The study also emphasizes the importance of the unsaturated zone in maintaining slope stability during prolonged rainfall events.

Summary: This paper presents a two-step simulation approach to investigate the influence and runout distance of rainfall-induced landslides. The complete process, from the initialization of instability to the post-failure flow, is simulated using a coupled hydro-mechanical finite element model and a coupled Eulerian-Lagrangian method. An equivalent-strength method is used to connect these two steps, and a rigorous method is developed to accurately quantify the influence and runout distance. The framework of using machine-learning models as surrogate models is found to be effective in stochastic analysis, reducing computational effort.

Summary: The study investigates the coupled effect of earthquakes and rainfall on landslide susceptibility. It reveals that earthquakes contribute to increasing the susceptibility to post-seismic rainfall-induced landslides, but this effect decreases over time.

Summary: A multi-temporal satellite radar interferometry technique is used to derive surface displacement patterns in Romania's slope environment for validating and improving a landslide susceptibility map. Geotechnical parameters and triggering factors for slope failure are identified, with physically based modeling proving effective for identifying unstable areas. The application of Small Baseline Subsets (SBAS) interferometry technique on C-band synthetic aperture radar (SAR) Sentinel-1 imagery helps assess kinematic characteristics, revealing a significant overlap with the infinite slope model's predictions. Refinement of the susceptibility map using InSAR results is proposed to uncover worst-case scenario dangers.

Summary: The Yerba Loca landslide in the Andes Main Cordillera is a large-scale multirotational slide, showing long-term slow deformation with a rapid increase in deformation rate in the months leading up to the failure. The event poses a hazard of rock avalanches, debris flows, river damming, and outburst floods that may endanger downstream communities.

Summary: This study investigated the effects of rainfall on landslide susceptibility, finding that under experimental conditions, no landslides occurred on a 5 degrees slope. It was also observed that coarser soils with gravels were more prone to landslides compared to fine soils. Additionally, steeper slopes, stronger rainfall, and coarser soils were all found to increase the amount of sediment yield.

Summary: The study found significant abnormal underground strain induced by heavy rainfall, reflecting two different rates of rainfall response: a fast response to rainwater loads and a slow response to water infiltration. Rivers can help accelerate runoff dispersion and reduce the impact time of heavy rainfall in mountainous areas. Results from deconvolution calculations show that the response strains are smaller in vertical coupling compared to isotropic coupling.

Summary: This paper uses two typical depth-averaged models to analyze a well-documented debris-flow event in the Cancia basin in July 2015. It is found that considering bed entrainment is necessary to reproduce the actual runout, while not considering this factor leads to unrealistic bank overflows. The comparison between measured and simulated inundated areas shows that both models perform well in simulating the erosion-deposition pattern, although there are differences in lateral spreading and depositional thickness between the two models.
