Function Model Based on Nonlinear Transient Rheology of Rocks: An Analysis of Decadal GNSS Time Series After the 2011 Tohoku‐oki Earthquake

Geophysical Research Letters, 2023
The postseismic Global Navigation Satellite System (GNSS) time series after the 2011 Tohoku‐oki earthquake is often empirically explained by one or more logarithmic and exponential decay functions.

Lithospheric Rheology in Southern California Derived From Novel Observations of Lake Unloading

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Recent Lake Cahuilla has undergone repeated filling and drying cycles over the past millennium, resulting in lithospheric and mantle loading responses. Two critical but less well‐constrained factors influencing these responses are the elastic plate thickness and mantle relaxation time.

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.

Kinematics and Dynamics of Normal Faults in Southern Tibet: Insights From the 2025 Mw 7.1 Dingri Earthquake

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Normal faults in southern Tibet have long suffered from limited ground‐based seismic and geodetic observations, constraining our understanding of both interseismic and coseismic processes and their interactions. The 2025 Mw 7.1 Dingri earthquake provides an opportunity to address these gaps.

Postseismic surface deformations due to lithospheric and asthenospheric viscoelasticity

Geophysical Research Letters, 1979
This paper proposes a model for postseismic surface deformations by attributing them to lithospheric and asthenospheric viscoelasticity. The model predicts that the deformations due to lithospheric viscoelasticity depend on the decrease in the effective shear modulus acting long after the lithospheric relaxation compared to that acting immediately ...

Interplate rheological contrast revealed by asymmetric deformation after the 2023 Kahramanmaraş earthquakes

Nature Communications
Postseismic surface deformation offers key insights into subsurface lithospheric rheology and earthquake fault behavior, yet geodetic data often fail to capture its full complexity.

Bayesian Inference of Fault Slip Heterogeneity and Overlap: Application to 2019 Ridgecrest Earthquakes and Afterslip

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Fault slip occurs in both seismic and aseismic styles with spatial variability across scales, yet non‐unique source inference limits our ability to resolve slip complexity and dynamics. Here we evaluate the effect of spatial smoothing regularization in Bayesian frameworks by comparing an unregularized (BUR) approach that samples distributed ...

A Statewide InSAR Velocity Map for California Produced by a Comprehensive Large Scale Analysis of ARIA Standard Products

Earth and Space Science, Volume 13, Issue 8, August 2026.
Abstract Routine Synthetic Aperture Radar (SAR) acquisitions from the Sentinel‐1 constellation enable monitoring of slow surface deformation (millimeters to centimeters per year), yet consistent and accessible pathways for producing validated, user‐ready velocity products remain limited.

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.
