Landslide Detection and Deformation Control Analysis in the Reservoir Area of Wudongde Hydropower Station by InSAR Observations

Earth and Space Science, Volume 12, Issue 4, April 2025.
Abstract After the construction of hydropower station, reservoir impoundment can directly affect the movement status of landslides within the reservoir area. Detecting landslides and revealing the relationship between landslide deformation and driving forces is crucial for reducing the threat of landslide hazards to residents and hydropower station in ...

Empirical Quantification of Topobathymetric Lidar System Resolution Using Modulation Transfer Function

Earth and Space Science, Volume 12, Issue 4, April 2025.
Abstract Topobathymetric scanning lidar deployed on unmanned aircraft systems is a powerful tool for high‐resolution mapping of the dynamic interface between topography and bathymetry. However, standardized methods for empirical resolution validation have not been widely adopted across lidar applications.

Tracing the Contribution of Abiotic Methane in Deep Natural Gases From the Songliao Basin, China Using Bulk Isotopes and Methane Clumped Isotopologue 12CH2D2

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 4, April 2025.
Abstract The identification and evaluation of abiotic methane remain an active research area due to uncertainties in traditional indicators that may lead to “false‐positive” detections. As an emerging isotopic tool, methane clumped isotope can provide novel information about the generation and post‐generation processes of methane gases.

Processes and Products of Turbidity Currents and Submarine Landslides in a Glacierized Fjord (Southwind Fjord, Baffin Island)

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 4, April 2025.
Abstract Sediment transported to fjords is redistributed by turbidity currents and sometimes fails on steep sidewall slopes, forming marine geohazards that are known to impact infrastructure. Since marine geohazards are poorly understood in Arctic Fjords due to lack of data and monitoring, a comprehensive study of Southwind Fjord, Baffin Island, was ...

Contemporaneous Triassic Calc‐Alkaline Volcanism and Fast‐Spreading Magmatism in the Western Tethys: Implications for the Eastern Mediterranean Palaeogeographic Evolution

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 4, April 2025.
Abstract Triassic calc‐alkaline volcanics that are mainly exposed in the Hellenides—Dinarides orogen, as well as eastwards in the Afyan Zone, are considered to constrain the petrogenetic mechanisms that led to their formation, and to unravel the geodynamic processes that occurred in the western Tethys, related to the NW Gondwana (Apulia) promontory and
