Mechanical Irreversibility and Strength Overcompensation in a Gypsum Dehydration–Rehydration Cycle

Abstract Dehydration–rehydration reactions of hydrous minerals modify rock strength, fluid transport, and deformation in reactive geological environments. Although dehydration‐induced weakening is widely studied, the mechanical consequences of subsequent rehydration remain poorly...

3D Subduction Interface Model for the Hikurangi Margin, New Zealand: Implications for Slow Slip Events

Abstract We present a new 3D Hikurangi subduction interface model by using an implicit modeling approach that integrates seismic‐reflection profiles, relocated hypocenters, focal mechanism orientations, and tomographic interpretations. The model reveals along‐strike transitions i...

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...
