Elucidating loessal landslide initiation in wood- and shrub-land by hydro-mechanical heterogeneity [PDF]

Hydrology and Earth System Sciences
Vegetation recovery on the Chinese Loess Plateau has markedly changed the hydrological and mechanical controls on hillslope erosion, shifting sediment production from runoff-driven erosion to gravity-driven processes such as rainfall-induced loessal ...

A New Surface Rupture of the 1556 Huaxian M ∼ 8.5 Earthquake Revealed by Rock Surface Luminescence Dating of a Bedrock Fault Scarp and Colluvial Wedges

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Bedrock fault scarps and their associated colluvial wedges provide key evidence for reconstructing paleoearthquakes. We apply rock surface luminescence dating to a bedrock scarp on the Huashan fault in central China, using OSL‐depth profiles (DPs) from multiple heights. Results reveal two coseismic displacements of 6.8 and >1.0 m.

MPES-YOLO: A Multi-Scale Lightweight Framework with Selective Edge Enhancement for Loess Landslide Detection

Remote Sensing
Loess landslides in northwestern China are highly unstable and difficult to distinguish due to sparse vegetation and their spectral and morphological similarity to the surrounding terrain.

Experimental analysis of rainfall-induced shallow landslides: a case study of a loess slope in Gaolan County, China

Frontiers in Earth Science
Rainfall is a major trigger for loess landslides, and understanding the associated deformation and failure mechanisms is essential for effective hazard mitigation. This study employed physical model experiments to investigate the hydrological response, deformation behavior, and failure evolution of homogeneous loess slopes subjected to intermittent ...

Co‐Seismic Deformation and Local Stress Evolution of the Philippines Earthquakes in July and October 2022 Revealed by InSAR and GNSS Observations

Earth and Space Science, Volume 13, Issue 2, February 2026.
Abstract On 27 July and 25 October 2022, an Mw 7.0 earthquake and an Mw 6.4 earthquake struck Abra, northwest of Luzon, Philippines, respectively, with a time interval of less than 3 months and a distance of about 16 km. In this research, interferometric synthetic aperture radar (InSAR) was utilized to retrieve the co‐seismic surface deformation field ...

Two‐dimensional Green–Ampt response of high‐capacity tensiometers and a conceptual pathway to correct dynamic water retention curve data

Vadose Zone Journal, Volume 25, Issue 1, January/February 2026.
Abstract In the investigation of the relationship between measured soil suction and the rate of saturation change, an increase in response time prevents the tensiometer from instantaneously reacting to changes in suction. Solving this problem requires a tensiometer response model, which is based on the measured data from partial drainage and adsorption

Progressive Failure and Stability Evolution of Highway Cut Slopes Under Excavation–Rainfall Coupling: An Evidence‐Based Review

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
Mountain highway cut slopes subjected to excavation disturbance and rainfall infiltration often undergo progressive deformation rather than instantaneous collapse. Although previous studies have examined excavation unloading, rainfall infiltration, weak structural control, and drainage anomalies, the time–dependent interaction among these processes has

Tributary‐Trunk Sedimentary Links in an Inter‐Dam River Reach: Lessons From Low‐Altitude High‐Gradient Forested Streams, the Dyje River (Czechia‐Austria)

River Research and Applications, Volume 41, Issue 10, Page 2157-2176, December 2025.
ABSTRACT This study employs two measures of connectivity, valley confinement index (VCI) and effective catchment area (ECA), combined with a field survey of active sediment sources (ASS) to unravel the tributary‐trunk sedimentary links in the 42.5 km long inter‐dam reach of the Dyje River, Czech‐Austrian border.
