Recent Crustal Deformation in West-Central South America [PDF]

, 2003
I use interferometric synthetic aperture radar (InSAR) to create maps of crustal deformation along the coast and within the volcanic arc of central South America. I image deformation associated with six subduction zone earthquakes, four volcanic centers,

Single-Pass Bistatic SAR Interferometry Using Fixed-Receiver Configurations: Theory and Experimental Validation [PDF]

, 2010
In this paper, bistatic interferometry using fixed-receiver configurations is addressed both theoretically and experimentally. The analytical expressions for interferometric phase and height sensitivity are derived, and a full interferometric processing ...

Ground deformation and fissure activity in Datong basin, China 2007–2010 revealed by multi-track InSAR

Geomatics, Natural Hazards & Risk, 2019
The Datong basin is one of the complex geologic environments in China. Several faults are distributed in the basin, and a number of hidden faults have been discovered within the basin. Ground fissures (GFs) and land subsidence occur in this region.

Evolution of Summit Magma Pressure During the 2018 Caldera Collapse at Kīlauea Volcano

Geophysical Research Letters, Volume 53, Issue 21, 16 November 2026.
Abstract We utilized geodetic data from the 16 May to 4 August 2018 caldera collapse sequence to refine the geometries and pressure evolution of two summit reservoirs at Kīlauea volcano: the shallower Halema‘uma‘u (HMM) and deeper South Caldera (SC) reservoirs.

A Fast 2-D Phase Unwrapping Algorithm Based on Convolutional Neural Network

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023
Two-dimensional phase unwrapping (2-D PU) is the process of converting the measured phase into the real phase in interferometric signal processing. Reliable unwrapping results are critical for digital elevation model generation using interferometric ...

Contrasting Responses of Winter Wheat to Waterlogged and Non‐Waterlogged Coal Mining Subsidence Revealed by Integrated DInSAR and UAV Red‐Edge Remote Sensing

Food and Energy Security, Volume 15, Issue 6, November/December 2026.
ABSTRACT This study aimed to clarify the spatiotemporal differences in the growth responses of winter wheat (Triticum aestivum L.) to mining subsidence across different growth stages and hydrological conditions in high‐groundwater‐level Coal–Grain Composite Areas (CGCAs).

Do Shallow Slip Deficits Reflect Fault Structural Maturity or Modeling Choices? A Comparative Analysis of Tibetan Strike‐Slip Earthquakes

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 11, November 2026.
Abstract InSAR‐constrained finite fault slip models are often used to characterize fault geometries and slip distributions of large continental earthquakes. A common feature of these models is a decrease in slip near the surface, commonly expressed as a percentage shallow slip deficit (SSD).

Deformation monitoring and safety stability evaluation study of high-altitude limestone dumps.

PLoS ONE
We employed synthetic aperture radar interferometry (InSAR) to assess the slope stability of a high-altitude landfill in Sangri County, Shannan, Tibet. To address the unique climatic conditions of high-altitude regions, the InSAR deformation monitoring ...

Correcting Unwrapping Errors Toward Reliable Rock Glacier Velocity From InSAR Time Series

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Rock Glacier Velocity is an Essential Climate Variable Permafrost Quantity, providing a quantifiable indicator of mountain permafrost evolution. Despite its wide usage, multi‐temporal InSAR often substantially underestimates rock glacier velocities compared to ground‐based measurements, limiting its reliability.
