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 ...

Coseismic Displacement Accumulation Between 1996 and 2019 Using A Global Empirical Law on Indonesia Continuously Operating Reference Station (InaCORS)

Journal of Geospatial Information Science and Engineering, 2019
Indonesia archipelago is one of the most populated country with active and complex tectonic zone in the world. Plate boundaries were assembled by four major plate which made the region not only vulnerable to earth-hazard but also prone to semi-dynamic ...

Core-mantle boundary deformations and J2 variations resulting from the 2004 Sumatra earthquake

, 2007
The deformation at the core-mantle boundary produced by the 2004 Sumatra earthquake is investigated by means of a semi-analytic theoretical model of global coseismic and postseismic deformation, predicting a millimetric coseismic perturbation over a ...

Mechanochemical Enhancement of Siderite‐To‐Magnetite Conversion in Faults

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Magnetic phases in fault rocks offer potential “geothermometers” for estimating frictional heating during fault slip. However, the thermochemical kinetics of magnetic minerals subjected to shear deformation in hydrothermal fluids‐conditions typical of natural faults ‐ remains poorly understood, hindering accurate temperature estimates.

Characteristics of normal-fault earthquake deformation in the Qinghai-Tibet Plateau revealed by InSAR

地球与行星物理论评, 2023
The north-south convergence and east-west extension of the Tibet Plateau are accommodated by a series of active strike-slip and normal faults, and normal-fault earthquakes are very active in the plateau. During 2020 to 2021, there were three normal-fault

Size‐Dependent Melting Behavior of Ultrafine Fault Rocks

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Dynamic weakening during earthquake ruptures is essential for accommodating fault slip and controlling seismic energy release. This weakening is localized within narrow principal slip zones (PSZs) that commonly contain nanoparticles in both natural and experimental faults.

Geometry, kinematics and rates of deformation in a normal fault segment boundary, central Greece [PDF]

, 2004
The geometry, kinematics and rates of deformation within a fault segment boundary between the ends of two major active normal fault segments have been investigated through examination of a faulted 126 ka marine terrace.

Limitations of earthquake coseismic deformation measurements using InSAR

International Journal of Remote Sensing
Interferometric Synthetic Aperture Radar (InSAR) is commonly used to measure earthquake coseismic deformation. However, InSAR cannot be used to effectively measure all types of coseismic deformation, and it is influenced by numerous factors. Currently, for the limitations of InSAR coseismic deformation measurement, only empirical judgements are used to

Diffuse deformation explains the magnitude-dependent coseismic shallow slip deficit

, 2023
Abstract Continental earthquakes produce both localized slip on faults and diffuse deformation in the surrounding medium, up to 1-2 kilometers from the faults. However, the origin of the diffuse deformation and its role in the rupture process are still debated.

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
