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 ...

Bidirectional Energy Transfer via Simultaneous Wave‐Particle Resonances in Inhomogeneous Space Plasmas

AGU Advances, Volume 7, Issue 4, August 2026.
Abstract Wave‐particle resonance is a key mechanism for energy transfer in collisionless plasmas with important implications for wave excitation and particle acceleration. Cyclotron resonance occurs when a particle's gyromotion synchronizes with the wave fields, with their interactions usually describable by quasilinear diffusion or nonlinear trapping.

Quantifying Uncertainty in OMNI Solar Wind Measurements Projected From L1 to the Earth's Bow Shock

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract Many routine measurements of the solar wind plasma and interplanetary magnetic field (IMF) are made at the L1 Sun–Earth Lagrange point; therefore, it is helpful to characterize the errors introduced in propagating these measurements to the near‐Earth environment.

Role of a Hidden Fault in the Early Process of the 2024 Mw7.5 Noto Peninsula Earthquake

Geophysical Research Letters
The 2024 Mw 7.5 Noto Peninsula, Japan, earthquake was initiated within the source region of intense swarm activity. To reveal the mainshock early process, we relocated the earthquake hypocenters and found that many key phenomena, including the mainshock ...

Foreshock Ion Properties at Earth's Bow Shock: Dependence on Upstream Conditions and Shock Geometry

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract Solar wind ion reflection at collisionless shocks regulates foreshock plasma dynamics, yet the quantitative dependence of foreshock ion properties on upstream and shock‐related parameters remains unclear, causing difficulties in predicting foreshock disturbances.

Probability Gain due to Foreshocks following Quiescence Tested by Synthetic Catalogs

, 1996
In order to investigate the factors that could contribute to the high values of the probability gain for foreshocks, we make use of synthetic catalogs generated by a computer program (Console et al., 1993b).

Improving Earthquake Forecasting for Europe Using Elliptic ETAS Aftershock Distribution Kernels

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract In the standard Epidemic‐Type Aftershock Sequence (ETAS) model, widely used for earthquake forecasting, aftershocks are distributed isotropically in space—in circular symmetry around the triggering event. This simplification neglects fault geometry and observed anisotropy in aftershock distributions.

Hydraulic Control of the Foreshocks and Mainshock of the 2017 Valparaíso, Chile, Earthquake

Geophysical Research Letters
Slow‐slip events (SSE) are a key mode of aseismic deformation and can enhance fault permeability through fracturing, enabling fluid migration from the overpressured oceanic crust to the plate interface.

Variations in precursory slip behavior resulting from frictional heterogeneity

Progress in Earth and Planetary Science, 2018
Precursory seismicity is often observed before a large earthquake. Small foreshocks occur within the mainshock rupture area, which cannot be explained by simple models that assume homogeneous friction on the entire fault.
