Deformational behaviours of alluvial units detected by advanced radar interferometry in the Vega Media of the Segura River, southeast Spain [PDF]

, 2016
It is widely known that differential land subsidence in a valley significantly controls its fluvial dynamics. Nevertheless, major uncertainty exists about the way in which alluvial forms respond to this process.

The 2025 MW7.0 Dingri Earthquake: Conjugate Normal Faulting of a Graben Structure in the Southern Xainza‐Dinggye Rift

Geophysical Research Letters, Volume 52, Issue 12, 28 June 2025.
Abstract The 2025 MW ${M}_{W}$7.0 Dingri earthquake, which struck southern Tibet on 7 January 2025, provides kinematic insights into extensional tectonics in the region. We use Sentinel‐1 and Lutan‐1 Synthetic Aperture Radar (SAR) data sets to analyze the coseismic displacement fields of this event.

Airborne and Spaceborne Mapping and Analysis of the Subglacial Lake D2 in David Glacier, Terra Nova Bay, Antarctica

Journal of Geophysical Research: Earth Surface, Volume 130, Issue 6, June 2025.
Abstract During the 2018–2019 Antarctic summer, the Korea Polar Research Institute and the University of Texas Institute for Geophysics collaborated on a helicopter‐based ice‐penetrating radar (IPR) survey over the active subglacial lake D2 (SLD2), located in the midstream of the David Glacier, Terra Nova Bay, Antarctica.

Terrestrial Water Storage Changes of Qinghai Lake on the Tibetan Plateau From Joint Inversion of GNSS and InSAR Data

Water Resources Research, Volume 61, Issue 6, June 2025.
Abstract Although geodetic techniques like Gravity Recovery and Climate Experiment have been widely applied to investigate terrestrial water storage (TWS) variations at regional or basin scales on the Tibetan Plateau (TP) caused by global warming, their coarse spatial has limited the study of individual lakes. In this study, we overcome this limitation

Research on the Prediction Method of 3D Surface Deformation in Filling Mining Based on InSAR‐IPIM

Energy Science &Engineering, Volume 13, Issue 5, Page 2401-2414, May 2025.
Aiming at a series of defects existing in the monitoring of mining area by InSAR technology, this paper proposes an insar‐ipim model to predict the three‐dimensional surface deformation of filling mining. The parameters of the model are inversed by using the group optimization algorithm slime bacteria algorithm proposed in 2020, and the empirical ...
