Probability and Recurrence of Maximum Magnitude Based on Stochastic Modeling of Internal Fault Geometry

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract The recognition that relay zones along faults can act as barriers to earthquake propagation implies that rupture size may not be random and earthquakes are constrained by fault geometry. Resolution and observational biases can, however, complicate the integration of actual fault zone geometries into deterministic modeling strategies, thereby ...

Seismicity acceleration and clustering before the 2015 Mw 7.9 Gorkha earthquake, Nepal

Seismica
In the last decade, several observations of peculiar seismic and geodetic phases preceding large earthquakes have been documented. Despite being a posteriori, these observations provide a better understanding of the processes involved in the nucleation ...

Temporal b-Value Variations through out a Seismic Faulting Process: The 2008 Taoyuan Earthquake in Taiwan

Terrestrial, Atmospheric and Oceanic Sciences, 2010
Temporal b-value variations have been completely obtained for the seismic faulting process of the 4 March 2008 Taoyuan earthquake (ML = 5.2), southern Taiwan.

Deep Crustal Magma‐Water Interaction During Oceanic Core Complex Termination of the Godzilla Megamullion in the Parece Vela Basin

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 9, September 2026.
Abstract Oceanic Core Complexes (OCCs) in back‐arc basins are not as thoroughly investigated, and their termination processes remain poorly understood. The Godzilla Megamullion is the largest known ceased OCC on Earth, yet magmatic and hydrothermal records from its termination are lacking.

Ground motion scenarios for the 1997 Colfiorito, central Italy, earthquake

Annals of Geophysics, 2008
In this paper we report the results of several investigations aimed at evaluating ground motion scenarios for the September 26th, 1997 Colfiorito earthquake (Mw 6.0, 09:40 UTC).

Characterizing Shallow Attenuation and Microearthquake Source Parameters Using a Downhole DAS Array at the Cape Modern Geothermal Field

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract Earthquake source parameters are crucial for assessing seismic hazard and understanding earthquake source physics. However, source parameter estimation is challenging for small earthquakes because they suffer notorious trade‐offs with shallow attenuation.

The Spatiotemporal Evolution of Creep on the Southern San Andreas Fault Between 2015–2021

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract The Southern San Andreas fault (SSAF) in the Coachella Valley experiences shallow creep and slow slip events (SSE), which re‐distribute stresses in the seismogenic zone and affect the potential of future earthquakes. Although average creep rates are relatively well‐constrained, untangling the details of spatiotemporal variation in creep along ...

Porous and Permeable Crystalline Basement: Evidence for Large‐Scale Hydraulic Connectivity at Kivetty, Finland

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract Porosity and permeability in crystalline shield basement are commonly assumed to be low, yet some fault zones sustain fluid circulation over kilometer scales. Here we quantify multiscale fault‐zone connectivity at Kivetty, central Finland, by integrating legacy deep‐borehole data, including packer tests, downhole logs, and a long‐term multi ...

Insights on Earthquake Nucleation Revealed by Numerical Simulation and Unsupervised Machine Learning of Laboratory-Scale Earthquake Nucleation

Abstract Understanding earthquake nucleation is vital for predicting and mitigating seismic events, saving lives, and enhancing construction practices in earthquake-prone areas. Cascade triggering and preslip triggering are prevalent theories, posing challenges in differentiation based on field observations.

The mixed mechanisms of large‐earthquake nucleation

Eos, Transactions American Geophysical Union, 2013
Where do big earthquakes come from? That's an important open question in seismology. High‐energy earthquakes often come from faults under high strain, but the mechanism that underlies their onset is still debated.
