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 ...

Postseismic Deformation Following the 2015 Mw7.8 Gorkha (Nepal) Earthquake: New GPS Data, Kinematic and Dynamic Models, and the Roles of Afterslip and Viscoelastic Relaxation

Journal of Geophysical Research: Solid Earth, 2020
We report Global Positioning System (GPS) measurements of postseismic deformation following the 2015 Mw7.8 Gorkha (Nepal) earthquake, including previously unpublished data from 13 continuous GPS stations installed in southern Tibet shortly after the ...

Uplift and subsidence associated with the great Aceh-Andaman earthquake of 2004 [PDF]

, 2006
Rupture of the Sunda megathrust on 26 December 2004 produced broad regions of uplift and subsidence. We define the pivot line separating these regions as a first step in defining the lateral extent and the downdip limit of rupture during that great M_w ≈

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.

Postseismic deformation in Chile: Constraints on the asthenospheric viscosity

Geophysical Research Letters, 1999
By means of a spherical Earth model with Maxwell rheology, an analysis of the postseismic deformation field due to the viscoelastic relaxation of the mantle and asthenosphere following the great 1960 Chile earthquake is performed. Due to the exceptional energy release of that earthquake, geomorphological evidences of postseismic deformation are ...

Rapid early afterslip characteristics of the 2010 moment magnitude (Mw) 8.8 Maule earthquake determined with sub-daily GPS solutions

Satellite Navigation
Ground surface deformations can be observed during the coseismic and postseismic periods. The accurate determination of displacements is of paramount importance for the assessment of the destructive power of large earthquakes and the characterization of ...

Present-day crustal deformation revealed active tectonics in Yogyakarta, Indonesia inferred from GPS observations

Geodesy and Geodynamics, 2020
We investigated the active crustal structure in Yogyakarta, Indonesia, using new and denser Global Positioning System (GPS) data. Deformation rate estimated from five years (2013–2018) of observations on 22 campaign might record broad deformation after ...

Afterslip and viscoelastic relaxation following the 2011 Tohoku-oki earthquake (Mw9.0) inferred from inland GPS and seafloor GPS/Acoustic data [PDF]

, 2015
We simultaneously estimate 2.5 years of afterslip and viscoelastic relaxation, as well as coseismic slip, for the 2011 Tohoku-oki earthquake. Displacements at inland GPS and seafloor GPS/Acoustic stations are inverted using viscoelastic Green's functions

Distributed Lower‐Crustal Flow Beneath the Central Xianshuihe–Xiaojiang Fault System: Reconciling Geodesy and Geology

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract We use recently compiled GNSS velocities across the Zemuhe‐Daliangshan fault zone, part of the central Xianshuihe‐Xiaojiang fault system, to reconcile a long‐standing mismatch between geodetic and geologic slip‐rate estimates. We show that conventional elastic dislocation models yield slip rates and locking depths that conflict with seismic ...

Poroelastic effects associated with earthquakes on overpressured reverse and normal faults

Frontiers in Earth Science
Earthquakes in fluid-saturated rocks induce sudden changes in pore-pressures that can lead to appreciable postseismic deformation. However, earthquakes can also release fluids from overpressured parts of the crust, which can also contribute to additional
