Seismogenic, coseismic and postseismic deformation and stress evolution of the 2008 Wenchuan earthquake: Numerical simulation analysis

Dizhi lixue xuebao, 2021
The 2008 MS 8.0 Wenchuan earthquake occurred in the Longmenshan fault zone, which has complex geological background, strong surface relief, and heterogeneous elastic-viscous structures; however, the seismic risk of the Longmenshan fault zone was ...

Kinematic Representations of Viscoelastic Postseismic Deformation

Earth and Space Science
AbstractFollowing large earthquakes, viscoelastic stress relaxation may contribute to postseismic deformation observed at Earth's surface. Mechanical representations of viscoelastic deformation require a constitutive relationship for the lower crust/upper mantle material where stresses are diffused and, for non‐linear rheologies, knowledge of absolute ...

Postseismic deformation following the 2016 Kumamoto earthquake detected by ALOS-2/PALSAR-2

Earth, Planets and Space, 2020
I have been conducting a study of postseismic deformation following the 2016 Kumamoto earthquake using ALOS-2/PALSAR-2 acquired till 2018. I apply ionospheric correction to interferograms of ALOS-2/PALSAR-2.

Mechanisms of Transient Postseismic Deformation Following the 2024 Mw 7.5 Noto Peninsula Earthquake Inferred From Horizontal and Vertical GNSS Data

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract The 2024 Mw 7.5 Noto Peninsula earthquake provided an opportunity to investigate postseismic deformation in a tectonically complex back‐arc region in central Japan, where Miocene normal faults are reactivated under present‐day compression.

Influence of anelastic surface layers on postseismic thrust fault deformation [PDF]

Journal of Geophysical Research: Solid Earth, 2000
We present the results of a systematic modeling study of postseismic deformation following blind thrust earthquakes. The results include qualitative and quantitative predictions of the surface movement caused by relaxation in viscoelastic near‐surface layers.

Coseismic and Early Postseismic Deformation of the 2020 Mw 6.4 Petrinja Earthquake (Croatia) Revealed by InSAR

Remote Sensing, 2023
The largest earthquake (Mw 6.4) in northwestern Croatia ruptured the faults near the city of Petrinja on 29 December 2020, at 11:19 UTC. The epicenter was located ~3 km southwest of Petrinja, ~40 km southeast of Zagreb, the capital of the Republic of ...

Detection of Interannual and Fine‐Scale Plate Coupling Variations Using Intraplate Earthquakes and Geodetic Data: Application to the Tohoku‐Oki Plate Boundary

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract We propose a method to infer detailed spatiotemporal variations in interplate coupling by integrating geodetic and seismic data. It examines whether focal mechanisms of intraplate earthquakes occurring near the plate interface align with the stressing rates caused by a geodetically derived slip‐deficit rate model, evaluating deviations from a ...

Role of poroelasticity during the early postseismic deformation of the 2010 Maule megathrust earthquake

Geophysical Research Letters, 2022
Megathrust earthquakes impose changes of differential stress and pore pressure in the lithosphere-asthenosphere system that are transiently relaxed during the postseismic period primarily due to afterslip, viscoelastic and poroelastic processes. Especially during the early postseismic phase, however, the relative contribution of these processes to the ...

Present‐Day Kinematics of Continental Greece and Balkans Revealed by Sentinel‐1 InSAR Data

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract The Balkan Peninsula hosts the highest seismic activity in Europe, marked by numerous Mw6+ earthquakes in diverse tectonic settings. Assessing tectonic surface deformation is crucial to understand the forces controlling kinematics and, ultimately, constraining geodynamic models. However, because measuring slow velocity rates (a few mm/yr) with

Interseismic Strain Accumulation and Partitioning in Hispaniola From GNSS and InSAR

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract We combine GNSS and InSAR observations to constrain the spatial distribution of strain across the northeastern Caribbean plate boundary, focusing on Hispaniola, to investigate strain partitioning and fault slip rates in an actively deforming tectonic setting with significant seismic hazard.
