Shear localization in a mature mylonitic rock analogue during fast slip [PDF]

, 2017
Highly localized slip zones, seen within ductile shear zones developed in nature, such as pseudotachylite bands occurring within mylonites, are widely recognized as evidence for earthquake nucleation and/or propagation within the ductile regime.

Subduction Parameters Controlling the Occurrence of Shallow and Deep Slow‐Slip Events (SSEs)

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract Slow‐slip events (SSEs) are transient aseismic fault‐slip phenomena that release tectonic stresses in a variety of tectonic environments, including subduction zones. In subduction margins, SSEs commonly occur along the plate interface at shallow (<20 km) and deep (30–60 km) depths.

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 ...

Grain‐Scale Heterogeneity in Fault Veins Influences Shear Rupture, Damage Distribution, and Microseismicity

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract Fault veins, mineral‐filled fractures within fault zones, exhibit substantial grain‐scale structural variation, yet, the mechanical consequences of this heterogeneity on fault deformation and seismicity remain poorly constrained. Here, we use the Discrete Element Method to investigate how grain‐scale heterogeneity in quartz veins, which are ...

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).

D‐Rex++: A New Tool to Simulate Olivine's Crystallographic Preferred Orientation in the Upper Mantle With Grain Size‐Coupled Rheology

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract Understanding the co‐evolution of olivine's crystallographic preferred orientation (CPO) and grain size is essential for capturing the dynamics of Earth's upper mantle. Existing CPO evolution models, such as D‐Rex, successfully predict CPO development but overpredict CPO strength and do not provide a physically meaningful grain size, limiting ...

GEOMETRIC EFFECTS ON EARTHQUAKE NUCLEATION ON BENT DIP-SLIP FAULTS

, 2011
The geometric effects on earthquake nucleation processes on bent dip-slip faults are studied using a slip strengthening and weakening friction law implemented in a two-dimensional quasi-static boundary integral model.

Linking Stress Drop and Slip Heterogeneity to Assess Source Rupture Directivity for Earthquakes in Central Italy

Terra Nova, Volume 38, Issue 3, Page 163-172, June 2026.
ABSTRACT In this study, we examine the relationship between Brune stress drop and fault slip where the stress drop is estimated using the Empirical Green's Function (EGF) method and slip distribution is derived from seismic and geodetic data inversion.
