FMLD: A Vertical Federated Learning Framework for Privacy‐Preserving Multimodal Landslide Detection

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 1, February 2026.
Abstract Landslides are among the most severe global geohazards posing a significant threat to human life and infrastructure. To support landslide detection and prediction, various geohazard monitoring approaches have been developed, such as optical remote sensing imagery, light detection and ranging, and ground‐based sensors, generating vast volumes ...

Mechanical Characteristics and Collapse Process Simulation of Tunnel Under Seismic Loading During Construction: A Case Study of a Deep Diversion Tunnel in Southwest China

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
To investigate the collapse mechanisms of diversion tunnels during construction under seismic loading, a coupled continuum‐discrete numerical simulation method was employed. Before seismic excitation, the initial support system was generally stable, with minor damage observed at the arch foot and arch crown (damage coefficient <0.033).

Mechanism of Multiple Anomalies Prior to Japan Earthquakes From 2021 to 2023: Lithosphere‐Coversphere‐Atmosphere‐Ionosphere Coupling Driven by Pressure‐Stimulated Rock Current

Earth and Space Science, Volume 12, Issue 6, June 2025.
Abstract This study investigated the underlying mechanism of multiple anomalies preceding the earthquakes occurred in Japan from 2021 to 2023. Key parameters, including induced magnetic field (IMF), atmospheric electric field (AEF), and total electron content (TEC), were analyzed to explore their spatiotemporal relationships with seismic activity.

Dynamic Stability Assessment of Stratified Argillaceous Sandstone Anchorages Under Seismic Load and Dry–Wet Cycles

Geofluids, Volume 2025, Issue 1, 2025.
For the suspension bridge construction located at the site of high seismic intensity, the stability of the anchorage foundation under the seismic load considerably affects the safety of the suspension bridge. Based on a suspension bridge case in southwest China, this study investigated the occurrence of earthquakes in this area and synthesized the ...
