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.

Mechanics and Statistics of Postseismic Shaking
Geophysical Research LettersAbstract Analysis of 2 weeks of continuous post‐seismic shaking after the 2019 M7.1 Ridgecrest, CA earthquake sequence using 4 nearby borehole seismometers reveals that continuous ground motions decay as Omori's law in time and follow the Gutenberg‐Richter distribution in logarithmic amplitude.

On the spatial distribution of postseismic activity in the Khibiny Mountains
Russian Journal of Seismology, 2020 Using data on the seismicity of the Khibiny Mountains, it was shown that the distances from seismic events triggered by an earlier seismic event to their triggers obey a power-law distribution with a parameter independent of the magnitude of the trigger event. It was previously shown by Felzer & Brodsky [2006], Richards-Dinger et al.

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 ...

Global postseismic gravity changes of a viscoelastic Earth [PDF]
Journal of Geophysical Research: Solid Earth, 1998 A spherically symmetric Earth model with a viscoelastic mantle and an inviscid core is used to study the gravitational perturbation due to a lithospheric shear dislocation in the coseismic and postseismic regime. Our approach is based on a quasi‐static solution of the equilibrium equations taking advantage of the normal mode technique for a layered ...

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

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.

Postseismic viscoelastic‐gravitational half space computations: Problems and solutions [PDF]
Geophysical Research Letters, 2004 We consider the problem of surface deformation arising from a fault in a semi‐infinite, elastic‐gravitational, and/or viscoelastic‐gravitational, plane‐layered medium, subject to an externally imposed gravitational acceleration g. Rundle [1981, 1982] presented a calculation in which self‐gravitation, represented by terms proportional to G are neglected,

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.

Crustal deformation in extensional regimes: Iceland, Nevada and SW Turkey [PDF]
, 1996 In 1991 a 23-point, 30 x 25 km, GPS geodetic network was established in the Hengill ridge-ridge-transform triple junction, SW Iceland. The GPS data were processed using the Bernese V3.2 software.
