Effects of Bulk Poroelasticity on Repeating Earthquake Sequences: Insights From Numerical Modeling

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract At seismogenic depths, faults and the surrounding rock are saturated with water. Fault slip induces volumetric strains in the bulk, causing compression or dilation of pore fluid, which alters pore pressure—a phenomenon known as the poroelastic effect. This pore pressure change can, in turn, influence fault slip behavior.

Rheologic constraints on the upper mantle from 5 years of postseismic deformation following the El Mayor‐Cucapah earthquake [PDF]

, 2016
We analyze five years of Southern California GPS data following the Mw=7.2 El Mayor‐Cucapah earthquake. We observe transient postseismic deformation which persists for 3 years at epicentral distances greater than ∼200 km.

Fault Slip Reversals Preceded the Intraplate 2021 Earthquake Series in the Vienna Basin (Central Europe)

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Fault‐slip reversals indicate transient stress changes and may illuminate earthquake preparation processes. Here we present high‐resolution observations of sub‐millimetric creep and slip reversals on the Altaquelle Fault, a Quaternary normal fault in the southern Vienna Basin, preceding a regionally significant intraplate earthquake sequence ...

Current Status of Postseismic Deformation Following the 2011 Tohoku-Oki Earthquake

, 2018
Postseismic deformation following the 2011 Tohoku-Oki earthquake has been observed by the Global Navigation Satellite System (GNSS) Earth Observation Network System (GEONET) and the Seafloor Geodetic Observation (SGO) over the past six and half years ...

Along‐Strike Coupling Heterogeneity in Cascadia's Slow‐Slip Zone Constrained by GNSS and Reduced‐Order Rate‐And‐State Friction Modeling

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Slow slip events (SSEs) in the Cascadia subduction zone exhibit along‐strike segmentation, where the central segment has longer recurrence intervals but smaller moments. We quantify the controls on this variability by combining geodetic inter‐SSE coupling inversion with Bayesian inference of a quasi‐dynamic rate‐and‐state friction SSE‐cycle ...

Decomposition of Postseismic Signals Following ≥Mw 6 Earthquakes on Sumatra Island Based on Sumatran GPS Array (SuGAr) Observations

Journal of Geospatial Information Science and Engineering
Indonesia, located at the convergence of four major tectonic plates, experiences frequent large earthquakes, particularly in Sumatra, due to the subduction of the Indo-Australian Plate and the Sumatra Fault Zone (SFZ).

How Long Can the Postseismic and Interseismic Phases of Great Subduction Earthquake Sustain? Toward an Integrated Earthquake‐Cycle Perspective

Geophysical Research Letters, 2023
The transition of subduction systems from postseismic to interseismic phase is an important indicator of their stress state and readiness for subsequent events.

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.

Coseismic and postseismic deformation of the 2011 Tohoku‐Oki earthquake constrained by GRACE gravimetry [PDF]

Geophysical Research Letters, 2012
Spaceborne gravimetry data from the Gravity Recovery And Climate Experiment (GRACE) are processed using spatio‐spectral Slepian localization analysis enabling the high‐resolution detection of permanent gravity change associated with both coseismic and postseismic deformation resulting from the great 11 March 2011 Mw 9.0 Tohoku‐Oki earthquake. The GRACE

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 ...
