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 ...

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

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.

Cascadia Slow Earthquake Behaviors Modulated by Tectonic and Environmental Forcings

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Slow earthquakes, including episodic tremor and slip (ETS), are highly sensitive to small stress perturbations, yet their links to tectonic and non‐tectonic forcings remain unclear. Previous studies suggest that annual hydrological cycle dominates the tremor seasonal behavior in northern Cascadia.

Abrupt Suppression of Tectonic Tremors Outside the Stress Shadow of Mendocino Earthquakes

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Tectonic tremor is a long‐duration noise‐like seismic signal associated with slow fault motion at major plate boundaries. Due to their remarkable sensitivity to stress perturbations, tremors serve as invaluable probes of the mechanical state and stress conditions deep within fault zones.

Competing Effects of Elastic Heterogeneity and Viscous Flow on Interseismic Coupling at Cascadia

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Interseismic coupling maps are important tools for estimating future earthquake hazard at subduction zones. Often interseismic coupling is estimated from surface velocities using a homogeneous elastic Earth model. However, inversions that incorporate viscoelastic mantle flow or elastic heterogeneity show that each can change the spatial ...

Increased far-field landslide hazards due to postseismic acceleration by the 2017 Mw 6.4 Nyingchi earthquake

International Journal of Applied Earth Observations and Geoinformation
Landslides represent a major type of earthquake-triggered geohazard, with their dynamic evolution influenced by the complex interaction of postseismic environmental factors.

Coseismic and Postseismic Slip Analysis of the 2024 Mw 7.0 Wushi Earthquake: Insights From InSAR Observations and Slip Inversion

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Analysis of fault slip behavior is crucial for assessing regional seismic hazards. This study employs Sentinel-1 SAR data to investigate the coseismic and postseismic deformation associated with the 2024 Mw 7.0 Wushi earthquake using Interferometric ...

Heterogeneous rheology controlled postseismic deformation of the 2011 Tohoku‐Oki earthquake

Geophysical Research Letters, 2016
Using two‐dimensional finite element modeling, we reproduced the observed postseismic deformation of the 2011 Tohoku‐Oki earthquake. Our model, which accounts for the lithosphere‐asthenosphere boundary and weak zones beneath volcanoes, was able to ...
