Beyond Rock Glaciers: Investigating Meltwater Contribution and Water Quality in High‐Mountain Springs From Different Landforms

Hydrological Processes, Volume 40, Issue 4, April 2026.
We investigated the water chemistry of springs from different landforms in high‐elevation Alpine catchments. Only in predisposing lithological settings, springs from landforms most likely influenced by ice had a poor water quality with high dissolved concentrations of metals.

Surface Deformation of the Nanga Parbat Crustal Diapir in the Northwestern Himalaya Imaged With GNSS and InSAR

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract The Nanga Parbat–Haramosh Massif located in the northwestern syntaxis of the Himalaya is an antiformal structure considered as a crustal diapir undergoing exhumation at a rate larger than 10 mm/yr since 1 Ma. Using GNSS horizontal surface velocities and a vertical and east–west decomposition of the Sentinel‐1 interferometric line‐of‐sight ...

Quantifying Seasonal Deformation Signals Using InSAR and Groundwater Models in the Mississippi River Delta, Baton Rouge, Louisiana

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 4, April 2026.
Abstract Seasonal land motion can be caused by processes above or below Earth's surface, often linked to natural changes in the hydrological cycle. In coastal deltaic systems, the coupling of water level changes between rivers and aquifers may cause significant surface deformation, but this process is poorly understood.

Monitoring the Land Subsidence Area in a Coastal Urban Area with InSAR and GNSS

Sensors, 2019
In recent years, the enormous losses caused by urban surface deformation have received more and more attention. Traditional geodetic techniques are point-based measurements, which have limitations in using traditional geodetic techniques to detect and ...

Frictional Heterogeneity Governs Slip Partitioning and Seismic Hazard in the 2023 Turkey Earthquake Doublet

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Quantifying fault frictional properties is fundamental to understanding slip behavior and seismic hazard. We analyze 2 years of Sentinel‐1 SAR data following the 2023 Turkey earthquake doublet using Independent Component Analysis‐enhanced Small Baseline Subset‐InSAR, to resolve postseismic deformation and invert for afterslip on the East ...

Integrated PSInSAR and SBAS-InSAR analysis for landslide detection and monitoring

Physics and Chemistry of the Earth, Parts A/B/C
The Lower Hunza section of the Karakoram Highway (KKH) in Northern Pakistan is highly prone to landslides due to gravity, tectonic stress, and erosion from glaciers and rivers, posing significant threats to infrastructure, communities, and KKH. Accurate and efficient detection and monitoring are essential for disaster monitoring and early warning. This

Complete Mining-Induced Subsidence Basin Reconstruction via Improved RIME-Based Probability Integral Parameter Inversion and SBAS-InSAR Residual Fusion

Applied Sciences
Large-gradient mining subsidence is difficult to reconstruct completely using small baseline subset interferometric synthetic aperture radar (SBAS-InSAR), because decorrelation and phase-unwrapping errors underestimate central subsidence, whereas the ...
