Performance of Common Scene Stacking Atmospheric Correction on Nonlinear InSAR Deformation Retrieval

Remote Sensing, 2023
Atmospheric Phase Screen (APS) is a major noise that suppresses the accuracy of InSAR deformation time series products. Several correction methods have been developed to perform APS reduction in the InSAR analysis, in which an algorithm called Common ...

A revised dislocation model of interseismic deformation of the Cascadia subduction zone [PDF]

Journal of Geophysical Research: Solid Earth, 2003
CAS3D‐2, a new three‐dimensional (3‐D) dislocation model, is developed to model interseismic deformation rates at the Cascadia subduction zone. The model is considered a snapshot description of the deformation field that changes with time. The effect of northward secular motion of the central and southern Cascadia forearc sliver is subtracted to obtain

An Improved Method of Mitigating Orbital Errors in Multiple Synthetic-Aperture-Radar Interferometric Pair Analysis for Interseismic Deformation Measurement: Application to the Tuosuo Lake Segment of the Kunlun Fault

Remote Sensing
It is challenging to precisely measure the slow interseismic crustal-deformation rate from Synthetic Aperture Radar (SAR) data. The long-wavelength orbital errors, owing to the uncertainties in satellite orbit vectors, commonly exist in SAR ...

Dual Role of a Subducted Seamount in Megathrust Rupture Initiation and Rupture Barrier

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Using high‐resolution 3D tomography and a relocated 2010–2022 earthquake catalog, we identify a seamount at 20–25 km depth beneath the Mompiche–Cojimíes region in the coastal forearc of Ecuador. This provides a rare, well‐resolved example of seamount preservation at these depths. The seamount coincides with a low interseismic‐coupling corridor

Aseismic slip and seismogenic coupling in the Marmara Sea: What can we learn from onland geodesy?

Geophysical Research Letters, 2017
Ever since the Mw7.4 Izmit earthquake in 1999, evaluation of seismic hazard associated with the last unbroken segments of the North Anatolian fault is capital.

Theories and applications of earthquake-induced gravity variation: Advances and perspectivesKey points

Earthquake Science, 2023
Earthquake-induced gravity variation refers to changes in the earth’s gravity field associated with seismic activities. In recent years, development in the theories has greatly promoted seismic deformation research, laying a solid theoretical foundation ...

Upper Mantle Heterogeneity and Weak Subduction Boundaries Control Crustal Stress in the Korean Peninsula

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Most earthquakes occur at plate boundaries, but some also strike within stable continental interiors. Although dominant causes of such intraplate earthquakes remain elusive, a prevailing hypothesis attributes intraplate stress and seismicity to variations in lithospheric thickness.

Shallow geological structures triggered during the Mw 6.4 Meinong earthquake, southwestern Taiwan

Terrestrial, Atmospheric and Oceanic Sciences, 2017
The Meinong earthquake generated up to ~10 cm surface displacement located 10 - 35 km west of the epicenter and monitored by InSAR and GPS. In addition to coseismic deformation related to the deep earthquake source, InSAR revealed three sharp surface ...

Fault slip rates and interseismic deformation in the western Transverse Ranges, California [PDF]

Journal of Geophysical Research: Solid Earth, 2013
AbstractTo better constrain fault slip rates and patterns of interseismic deformation in the western Transverse Ranges of southern California, we present results from analysis of GPS and interferometric synthetic aperture radar (InSAR) data and three‐dimensional mechanical and kinematic models of active faulting.

Large‐Scale Deformation, Strain Characteristics, and Locking Distribution of the Qilian‐Haiyuan Fault System

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract The Qilian‐Haiyuan fault system is the main tectonic boundary of the northeastern Tibetan Plateau, controlling the regional tectonic deformation and seismic activity. Extensive Sentinel‐1 SAR data (2014–2021) are used to map the regional tectonic deformation, strain distribution, and locking along primary and secondary faults.
