Contrasting mechanisms of present-day vertical deformation along the northeastern Tibetan Plateau: Insights from 3-D viscoelastic modeling

Summary The northeastern margin of the Tibetan Plateau exhibits pronounced spatial variations in present-day vertical crustal deformation, yet the mechanisms controlling these differences remain debated. In particular, contrasting uplift patterns are observed between the Liupansh...

Scenario-based physically informed assessment of rainfall- and earthquake-induced landslide failure probability across China

Abstract Background Landslides are among the most widespread and destructive geological hazards in China, driven by complex mechanisms involving multiple interacting factors. Their impacts are particularly severe when intense rainfall and strong ground motion occur in combination...

Multi-Temporal UAV Observations of Post-Seismic Surface Collapse Evolution Following the 2026 M5.2 Liuzhou Double Earthquake in a Karst Terrain, Guangxi Province, China

On 18 May 2026, a M5.2 double earthquake struck the Taiyangzhen area of Liunan District, Liuzhou City, Guangxi, China, triggering shallow surface collapses in this karst terrain. We conducted three UAV orthophoto surveys of the meizoseismal area on 20 May, 23 May, and 24 May, and...

Super-resolution downscaling of WRF-based typhoon wind fields over complex coastlines using a decoupled physics-guided U-Net

Accurate kilometer-scale typhoon wind fields are important for coastal hazard assessment, but Weather Research and Forecasting (WRF)-based dynamical downscaling remains computationally expensive, while traditional statistical methods often fail to capture localized topographic ef...
