Insights into the Arabia–Anatolia plate collision from integrated SAR analysis and detailed modelling of the 2023 Türkiye–Syria earthquakes
We examine the 6 February 2023 Türkiye–Syria earthquakes using an extensive SAR dataset, addressing some limitations of previous studies. Large surface displacements caused significant loss of coherence in the Sentinel-1 Differential SAR Interferometry (DInSAR) results and prior analyses using…

Fatigue damage evolution mechanism of sandstone under Freeze–Thaw and loading rate coupling based on NMR and AE techniques
The influence of freeze-thaw damage effects on the fatigue mechanical response characteristics and damage mechanisms of sandstone was examined. Three loading rates (0.2, 0.4, and 0.6 kN/s) and four freeze-thaw cycles (0, 15, 30, and 45 cycles) were used in cyclic loading-unloading tests to…

Geospatial assessment and mapping of water-induced soil erosion in a semiarid region of the MENA using GIS-based RUSLE modeling
Soil erosion is a major environmental issue throughout the Middle East and North Africa, where it contributes to accelerated land degradation, declining soil fertility, and increased sediment accumulation in reservoirs. These pressures are especially pronounced in the Upper-Bousselam Watershed, an…

Mechanical degradation and microcrack evolution of weathered basalt under freeze–thaw cycles
Freeze-thaw cycles (FTCs) play an important role in the degradation of rock masses and the stability of slopes in cold, high-altitude regions. However, the degradation behaviour of basalt with different weathering degrees under freeze-thaw (F-T) conditions remains insufficiently understood. In this…

Petrogenesis of ultramafic and mafic rock series from the North Pyrenean Castillon massif (Ariège, France): evidence of magma–crust interactions in the Ordovician?
The Castillon massif, in the northern Pyrenees, features a complex of decimetric to metric ultramafic and mafic layers emplaced within metasedimentary series (from the bottom to the top: garnet, sillimanite, and kyanite-bearing gneisses and sillimanite + cordierite-bearing gneisses). Ultramafic and…
