Summary: This review discusses the temporal and spatial distribution of surface uplift in the Tibetan Plateau and the geodynamic mechanisms behind it. The initial collision between India and Asia and the subsequent formation of the high Tibetan Plateau are still not well understood, but the uplift is primarily controlled by delamination and break-off of the subducted Indian and Asian lithosphere.

Summary: This study conducted triaxial compression tests on coal under different gas pressure conditions to explore the influence mechanism of gas pressure on coal deformation, failure, and energy evolution. The mechanical properties, acoustic emission energy characteristics, and nonlinear characteristics of coal containing gas were obtained based on the test data. A theoretical formula for analyzing energy evolution was introduced and verified by test data. The research results indicate that energy rate can be used as a new effective mechanical parameter to analyze and predict the damage and failure characteristics of coal. The findings on energy dissipation characteristics and the defined ratio of dissipative energy rate and input energy rate provide insights for understanding the fracturing evolution and energy driving mechanism of coal.

Summary: On 15 January 2022, the eruption of the Hunga-Tonga volcano in the South Pacific Ocean resulted in a violent underwater explosion, causing tsunami waves and atmospheric pressure disturbances. Numerical simulation shows an excellent agreement between the simulated wave arrival time and observations.

Summary: This study provides high-resolution mapping of ice motion and thickness for glaciers worldwide, and estimates the global ice volume. The results show that the contribution of world's glaciers to sea-level rise is 20% less than previously thought. Additionally, there are notable changes in ice resources in low latitude regions, with an increase of 37% in the Himalayas and a decrease of 27% in the tropical Andes of South America, which affects water availability for local populations.

Summary: Xinjiang, China, has experienced significant warming and moistening climate changes, leading to increases in precipitation and warm extremes, as well as decreases in cold extremes. These climate changes have resulted in glacier shrinkage, decreased snow cover, increased river runoff, and potential adverse ecological effects.

Summary: Landslides are catastrophic natural hazards that can cause loss of life, property damage, and economic disruption. In this study, an image-based two-phase data-driven framework is proposed for detecting and segmenting landslide regions using satellite images. This framework outperforms other benchmarking algorithms in accurately segmenting landslides.

Summary: A one-dimensional radial three-phase flow model of water-rock-silt was established to investigate the hydraulic characteristics of fault rock during water-silt inrush. The accuracy of the proposed model was verified through laboratory tests and the temporal-spatial distribution of hydraulic properties was obtained.

Summary: This study proposes novel predictive models for flood and erosion susceptibility mapping in mountainous watersheds. The study also prioritizes the existing sub-basins based on their susceptibility to erosion and flood. A comparative analysis of different models and their ensemble is performed to determine the best model for predicting susceptibility. The results show that the ensemble model has the highest predictive performance and the sub-basins SW3 and SW5 are identified as highly sensitive to flood and soil erosion, respectively.

Summary: The oxidation of fossil fuels leads to significant CO2 emissions, contributing to global warming. Storing CO2 in underground formations is a potential solution, but the presence of organic material in geological formations affects storage potential. Studying the wetting characteristics and the impact of organic material is crucial for understanding CO2 behavior and enhancing storage capacity.
