Monitoring Groundwater Pumping Using Time‐Lapse Tomography From Ambient Seismic Noise

Water Resources Research, Volume 62, Issue 4, April 2026.
Abstract Management of water resources will be of critical importance as the effects of climate change accelerate. This implies the need to monitor water resources with high spatial and temporal resolution. One way to meet this need could be passive seismic methods using ambient seismic noise. In this study, we present a novel approach using time‐lapse

Decoupling Hydroclimatic Controls on Displacement of Retrogressive Thaw Slumps in Qinghai‐Tibet Plateau

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract The retrogressive thaw slumps (RTS), a prevalent form of thermokarst hazard in permafrost regions, are increasing in both number and extent under contemporary changing environments. On the Qinghai‐Tibet Plateau, RTS threaten transportation infrastructure and disrupt ecosystems.

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 ...

REDEFINING SUBSIDENCE AND UPLIFT HOTSPOTS ON JAVA ISLAND, INDONESIA: MULTI-TEMPORAL INSAR FOR LARGE-SCALE LAND DEFORMATION MAPPING

Rudarsko-geološko-naftni Zbornik
Java Island experiences complex and nonlinear land deformation resulting from the interplay of natural and anthropogenic factors. Previous studies predominantly investigated urban subsidence, leaving island-wide patterns less understood.

Monitoring of Merapi Volcano Deformation Using Interferometry Synthetic Aperture Radar (InSAR) Technique [PDF]

, 2014
The Merapi volcano is the most active volcano in Indonesia until now, because of eruption occur every two or five years. To minimize the impact of volcanic eruptions need to monitor the volcanic activity, one effort in monitoring is to monitor the ...

Holistic Retrieval of Absolute Coseismic Displacement Fields From Single Interferograms via Physics‐Aware GANs

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract The efficacy of rapid seismic response is fundamentally constrained by the sequential, multi‐step nature of conventional InSAR processing, where error propagation and reliance on auxiliary data hinder automation. Here, we present a holistic framework using Physics‐Aware Generative Adversarial Networks (GANs) to directly retrieve absolute ...

Multidisciplinary approach to revisit the state of activity of a deep‐seated gravitational slope deformation in the frame of the Quaternary geomorphological evolution of the Central Apennines (Italy)

Earth Surface Processes and Landforms, Volume 51, Issue 3, March 2026.
Abstract Evaluating the state of activity of Deep‐Seated Gravitational Slope Deformation (DSGSD) is a challenge that requires multidisciplinary analytical approaches. This research focuses on the slope‐scale gravitational process, framing the role of the Quaternary morphodynamics of a river valley where multiple DSGSDs coexist, to reconstruct the ...

Reservoir characterization in an underground gas storage field using joint inversion of flow and geodetic data [PDF]

, 2015
Characterization of reservoir properties like porosity and permeability in reservoir models typically relies on history matching of production data, well pressure data, and possibly other fluid-dynamical data.
