Effects of Stress and Friction Heterogeneity on Spatiotemporal Complexity of Seismic and Aseismic Slip on Strike‐Slip Faults

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 12, December 2025.
Abstract Numerical and laboratory models of earthquake cycles on faults governed by rate‐and‐state friction often show cycle‐invariant behavior, while natural faults exhibit considerable variability in slip history. Possible explanations include heterogeneities in fault stress and frictional properties. We investigate how various types of heterogeneity

Controls of Dynamic and Static Stress Changes and Aseismic Slip on Delayed Earthquake Triggering: Application to the 2019 Ridgecrest Earthquake Sequence

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 12, December 2025.
Abstract Dynamic earthquake triggering often involves a time delay relative to the peak stress perturbation. In this study, we investigate the physical mechanisms responsible for delayed triggering. We compute detailed spatiotemporal changes in dynamic and static Coulomb stresses at the 2019 Mw ${M}_{w}$ 7.1 Ridgecrest mainshock hypocenter, induced by ...

Spatial–temporal properties of afterslip associated with the 2015 Mw 8.3 Illapel earthquake, Chile

Earth, Planets and Space, 2021
In order to characterize the spatial–temporal properties of postseismic slip motions associated with the 2015 Illapel earthquake, the daily position time series of 13 GNSS sites situated at the near-field region are utilized.

Strain Rates Along the Alpine‐Himalayan Belt From a Comprehensive GNSS Velocity Field

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 12, December 2025.
Abstract The Alpine‐Himalayan belt is one of Earth's most dynamic and complex regions, characterized by intense tectonic deformation and seismicity. Comprehensive analyses of continental‐scale crustal deformation and seismic hazards along this extensive orogenic belt require the compilation of large geodetic data sets.

Shallow coseismic slip and downdip afterslip associated with the 2022 MW6.7 Menyuan (China) earthquake

Geodesy and Geodynamics
Investigating the spatial distribution of coseismic rupture, postseismic afterslip, and their interactions is essential for understanding the heterogeneous frictional characteristics of faults, and seismic hazard assessments.

Reactivated afterslip induced by a large regional earthquake, Fiordland, New Zealand

Geophysical Research Letters, 2016
AbstractThe evaluation of seismic hazard along active faults requires knowledge of the long term slip rate, the portions of the fault which are accumulating strain, and the magnitude, number, and location of past earthquakes. Aseismic slip will lower the long‐term seismic potential, but the distribution of seismic versus aseismic slip along faults is ...

Range‐Parallel Extension of the Andes in the 2020 Mw 5.7 Humahuaca Earthquake

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 12, December 2025.
Abstract Normal‐faulting earthquakes in mountain ranges provide important constraints on the dynamics of mountain building. To date, well‐documented examples of range‐parallel extension come primarily from the Tibetan Plateau, limiting our ability to test different models for its cause.

Probing time-dependent afterslip and viscoelastic relaxation following the 2015 Mw7.8 Gorkha earthquake based on the 3-D finite-element model

Earth, Planets and Space, 2020
We analyzed daily displacement time series from 34 continuous GPS stations in Nepal and 5 continuous GPS stations in South Tibet, China, and extracted the first 4.8 years of postseismic motion after the 2015 Mw7.8 Gorkha earthquake.

PyQuake3D: A Python Tool for 3‐D Earthquake Sequence Simulations of Seismic and Aseismic Slip

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 4, December 2025.
Abstract Simulating the full spectrum of fault slip behavior—from slow aseismic creep to dynamic earthquake rupture—is essential for advancing our understanding of fault mechanics and long‐term seismic hazard. However, few open‐source tools provide efficient three‐dimensional modeling of these processes with the flexibility needed for research across ...
