Crackling noise

JP Sethna, KA Dahmen, CR Myers - Nature, 2001 - nature.com
Crackling noise arises when a system responds to changing external conditions through
discrete, impulsive events spanning a broad range of sizes. A wide variety of physical …

Collective behavior of earthquakes and faults: Continuum‐discrete transitions, progressive evolutionary changes, and different dynamic regimes

Y Ben‐Zion - Reviews of Geophysics, 2008 - Wiley Online Library
Crustal deformation patterns are affected by multiscale granulation and healing processes
associated with phase transitions between continuum and discrete states of rocks. The …

Elastodynamic analysis for slow tectonic loading with spontaneous rupture episodes on faults with rate‐and state‐dependent friction

N Lapusta, JR Rice, Y Ben‐Zion… - Journal of Geophysical …, 2000 - Wiley Online Library
We present an efficient and rigorous numerical procedure for calculating the elastodynamic
response of a fault subjected to slow tectonic loading processes of long duration within …

Dynamic ruptures in recent models of earthquake faults

Y Ben-Zion - Journal of the Mechanics and Physics of Solids, 2001 - Elsevier
We discuss several problems of dynamic rupture relevant to mechanics of earthquake faults,
material sciences, and physics of spatially extended dissipative systems. The problems …

Universal nucleation length for slip‐weakening rupture instability under nonuniform fault loading

K Uenishi, JR Rice - Journal of Geophysical Research: Solid …, 2003 - Wiley Online Library
We consider the nucleation of instability on a slip‐weakening fault subjected to a
heterogeneous, locally peaked “loading” stress. That stress is assumed not only to gradually …

Cracks, pulses and macroscopic asymmetry of dynamic rupture on a bimaterial interface with velocity-weakening friction

JP Ampuero, Y Ben-Zion - Geophysical Journal International, 2008 - academic.oup.com
We study in-plane ruptures on a bimaterial fault governed by a velocity-weakening friction
with a regularized normal stress response. Numerical simulations and analytical estimates …

Earthquake ruptures modulated by waves in damaged fault zones

Y Huang, JP Ampuero… - Journal of Geophysical …, 2014 - Wiley Online Library
Faults are usually surrounded by damaged zones of lower elastic moduli and seismic wave
velocities than their host rocks. If the interface between the damaged rocks and host rocks is …

Source properties of dynamic rupture pulses with off‐fault plasticity

AA Gabriel, JP Ampuero, LA Dalguer… - Journal of Geophysical …, 2013 - Wiley Online Library
Large dynamic stresses near earthquake rupture fronts may induce an inelastic response of
the surrounding materials, leading to increased energy absorption that may affect dynamic …

Earthquake scaling relations for mid‐ocean ridge transform faults

MS Boettcher, TH Jordan - Journal of Geophysical Research …, 2004 - Wiley Online Library
A mid‐ocean ridge transform fault (RTF) of length L, slip rate V, and moment release rate
can be characterized by a seismic coupling coefficient χ= AE/AT, where AE∼/V is an …

Large earthquake cycles and intermittent criticality on heterogeneous faults due to evolving stress and seismicity

Y Ben‐Zion, M Eneva, Y Liu - Journal of Geophysical Research …, 2003 - Wiley Online Library
We analyze evolving stress and seismicity generated by three realizations of a discrete
model of a strike‐slip fault in a three‐dimensional (3‐D) elastic half space using five …
