Earthquake energy dissipation in a fracture mechanics framework

DS Kammer, GC McLaskey, RE Abercrombie… - Nature …, 2024 - nature.com
Earthquakes are rupture-like processes that propagate along tectonic faults and cause
seismic waves. The propagation speed and final area of the rupture, which determine an …

Do faults preserve a record of seismic slip: A second opinion

CD Rowe, WA Griffith - Journal of Structural Geology, 2015 - Elsevier
Exhumed fault zones offer insights into deformation processes associated with earthquakes
in unparalleled spatial resolution; however it can be difficult to differentiate seismic slip from …

Progressive damage behaviours of triaxially confined rocks under multiple dynamic loads

K Liu, J Zhao - Rock Mechanics and Rock Engineering, 2021 - Springer
Investigation of rock progressive damage under static confinement and strain rates facilitates
the generation mechanism of natural fault damage zones. A triaxial Hopkinson bar …

Relation between continental strike‐slip earthquake segmentation and thickness of the crust

Y Klinger - Journal of Geophysical Research: Solid Earth, 2010 - Wiley Online Library
High‐resolution maps of large continental strike‐slip earthquake surface ruptures show that
they are formed of fault segments. These segments are bounded by fault bends, step overs …

Conditions governing the occurrence of supershear ruptures under slip‐weakening friction

EM Dunham - Journal of Geophysical Research: Solid Earth, 2007 - Wiley Online Library
A general theory for transitions between sub‐Rayleigh and intersonic rupture speeds is
developed for faults governed by slip‐weakening friction. The transition occurs when …

Dynamic fracturing by successive coseismic loadings leads to pulverization in active fault zones

FM Aben, ML Doan, TM Mitchell… - Journal of …, 2016 - Wiley Online Library
Previous studies show that pulverized rocks observed along large faults can be created by
single high‐strain rate loadings in the laboratory, provided that the strain rate is higher than …

Community‐driven code comparisons for three‐dimensional dynamic modeling of sequences of earthquakes and aseismic slip

J Jiang, BA Erickson, VR Lambert… - Journal of …, 2022 - Wiley Online Library
Dynamic modeling of sequences of earthquakes and aseismic slip (SEAS) provides a self‐

Off‐fault plasticity and earthquake rupture dynamics: 1. Dry materials or neglect of fluid pressure changes

EL Templeton, JR Rice - Journal of Geophysical Research …, 2008 - Wiley Online Library
We analyze inelastic off‐fault response during earthquakes. Spontaneous crack‐like
rupture, with slip weakening, is modeled in 2‐D plane strain using an explicit dynamic finite …

Effects of low‐velocity fault damage zones on long‐term earthquake behaviors on mature strike‐slip faults

P Thakur, Y Huang, Y Kaneko - Journal of Geophysical …, 2020 - Wiley Online Library
Mature strike‐slip faults are usually surrounded by a narrow zone of damaged rocks
characterized by low seismic wave velocities. Observations of earthquakes along such faults …

Why do great continental transform earthquakes nucleate on branch faults?

RS Stein, P Bird - Seismological Research Letters, 2024 - pubs.geoscienceworld.org
The five M w≥ 7.8 continental transform earthquakes since 2000 all nucleated on branch
faults. This includes the 2001 M w 7.8 Kokoxili, 2002 M w 7.9 Denali, 2008 M w 7.9 …
