Evidence for and implications of self-healing pulses of slip in earthquake rupture
TLDR
In this article, a qualitative model is presented that produces self-healing slip pulses, which is the key feature of the model is the assumption that friction on the fault surface is inversely related to the local slip velocity, and the model has the following features: high static strength of materials (kilobar range), low static stress drops (in the range of tens of bars).About:

Heterogeneity and the earthquake magnitude-frequency distribution
Sandra J. Steacy,John McCloskey +1 more
TL;DR: In this article, the authors investigated the relation between heterogeneity and the magnitude-frequency distribution in a cellular automaton that includes new nearest-neighbor stress transfer rules which produce realistic stress concentrations.

Frictional shear cracks
Efim A. Brener,V. I. Marchenko +1 more
TL;DR: Baumberger et al. as discussed by the authors calculate the crack velocity as a function of the applied shear stress and find that the main dissipation comes from the macroscopic region and is mainly due to the friction at the interface.

Effects of Off-fault Damage on Earthquake Rupture Propagation: Experimental Studies
TL;DR: In this article, the scaling properties of the interaction between the crack-tip field and pre-existing off-fault damage (i.e., no new damage is created) are explored using an analytic model for a nonsingular slip-weakening shear slip-pulse and verified using the velocity history of a slip pulse measured in the laboratory and a direct laboratory measurement of damage zones of various widths adjacent to the fault.

Contrasting rupture processes during the April 11, 2010 deep-focus earthquake beneath Granada, Spain
TL;DR: The Mw=6.3 deep-focus earthquake beneath Granada, Spain, in 2010 consisted of three resolvable sub-events occurring within a time span of 5 s.

Upgrading a synthetic seismicity model for more realistic fault ruptures
Russell Robinson,Rafael Benites +1 more
TL;DR: In this article, a quasi-static synthetic seismicity model for multiple interacting faults of any orientation is upgraded to include a more realistic rupture model, where time is introduced into the rupture process via a patch interaction delay in proportion to distance/shear wave velocity.

The Determination of the Elastic Field of an Ellipsoidal Inclusion, and Related Problems
TL;DR: In this paper, it is shown that to answer several questions of physical or engineering interest, it is necessary to know only the relatively simple elastic field inside the ellipsoid.
Journal ArticleDOI
Tectonic stress and the spectra of seismic shear waves from earthquakes
TL;DR: In this paper, an earthquake model is derived by considering the effective stress available to accelerate the sides of the fault, and the model describes near and far-field displacement-time functions and spectra and includes the effect of fractional stress drop.

Theoretical basis of some empirical relations in seismology
Hiroo Kanamori,Don L. Anderson +1 more
TL;DR: In this article, an empirical relation involving seismic moment M, energy E, magnitude M, and fault dimension L (or area S) is discussed on the basis of an extensive set of earthquake data (M_S ≧ 6) and simple crack and dynamic dislocation models.

Modeling of rock friction: 1. Experimental results and constitutive equations
TL;DR: In this paper, it is shown that the strength of the population of points of contacts between sliding surfaces determines frictional strength and that the number of contacts changes continuously with displacements.
