Linking Stress Drop and Slip Heterogeneity to Assess Source Rupture Directivity for Earthquakes in Central Italy

open access: yesTerra Nova, Volume 38, Issue 3, Page 163-172, June 2026.
ABSTRACT In this study, we examine the relationship between Brune stress drop and fault slip where the stress drop is estimated using the Empirical Green's Function (EGF) method and slip distribution is derived from seismic and geodetic data inversion.

Land Subsidence Susceptibility Mapping in Semi‐Arid Regions Using PS‐InSAR and Tree‐Based Ensemble Machine Learning: A Case Study From Çumra, Türkiye

open access: yesTransactions in GIS, Volume 30, Issue 4, June 2026.
ABSTRACT Land subsidence is an increasing environmental hazard in semi‐arid agricultural basins where intensive groundwater abstraction, compressible geological units, and expanding land‐use pressures interact. This study presents a PS‐InSAR and machine‐learning‐based framework for land subsidence susceptibility mapping in the Çumra District of the ...

Monitoring mining-induced subsidence by integrating differential radar interferometry and persistent scatterer techniques

open access: yesEuropean Journal of Remote Sensing, 2021
Surface subsidence is a dominant component of the displacement vector triggered by underground mining. Over the last few decades, Differential Interferometry Synthetic Aperture Radar (DInSAR) has been used to efficiently monitor this phenomenon with ...

A method for extracting sub-regional deformation of mining subsidence based on SAR technology

open access: yesMeikuang Anquan, 2022
Aiming at the problem of low applicability of differential interferometric synthetic aperture radar(DInSAR) and offset tracking(OT) technologies in the intersection area of small-scale and large-scale deformation in the edge and center of the subsidence ...

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

open access: yesHydrological 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.

Airborne DInSAR time series at X-band

open access: yes, 2010
Differential SAR Interferometry (DInSAR) is a remote sensing technique which allows monitoring ground deformation with accuracy of the order of the transmitted wavelength by exploiting the phase difference (interferogram) of two temporally separated SAR ...

Monitoring and early-warning of surface deformation in mine goaf based on InSAR

open access: yesMeikuang Anquan, 2022
To study the monitoring and early warning ability of DInSAR and SBAS InSAR for mine earthquake collapse in goaf area, this paper uses the two InSAR techniques to process the 11 scene C-band Sentinel-1A SAR images before and after the mine earthquake to ...

Permafrost Terrain Disturbance Susceptibility in the Nacho Nyäk Tagé (Stewart River) Watershed, Yukon, Canada

open access: yesPermafrost and Periglacial Processes, Volume 37, Issue 2, Page 203-226, April/June 2026.
ABSTRACT The Nacho Nyäk Tagé (Stewart River) watershed in central Yukon (Canada) is characterized by discontinuous permafrost that is locally highly sensitive to thaw. This study aims to map the spatial distribution of permafrost terrain disturbances (PTDs) in the watershed and model thaw susceptibility to support community‐led land‐use planning by the

Identification of Sea Level Rise and Land Subsidence Based on Sentinel 1 Data in the Coastal City of Pekalongan, Central Java, Indonesia

open access: yesJurnal Kelautan Tropis, 2023
Sea level rise is a pure impact of climate change. However, the process of studying sea level rise must include local factors that influence such as land subsidence.

Hydrometeorological and Topographic Controls on Rock Glacier Kinematics: A Case Study From Southeastern Alaska

open access: yesJournal of Geophysical Research: Earth Surface, Volume 131, Issue 4, April 2026.
Abstract Rock glacier kinematics are indicators of alpine climate change, yet the relative influence of thermal and hydrological processes on their motion remains poorly constrained. This uncertainty limits our ability to predict how these permafrost landforms will respond to ongoing climate change.
