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:

Repeating earthquake finite source models: Strong asperities revealed on the San Andreas Fault
TL;DR: In this paper, the authors investigated the rupture process of a sequence of repeating Mw 21 earthquakes on the San Andreas Fault in Parkfield spanning the occurrence of the September 28, 2004 mainshock by inverting seismic moment rate functions obtained from empirical Green's function deconvolution.

Rough faults, distributed weakening, and off-fault deformation
W. Ashley Griffith,W. Ashley Griffith,Stefan Nielsen,Giulio Di Toro,Giulio Di Toro,Steven A.F. Smith +5 more
TL;DR: In this article, the authors report systematic spatial variations in fault rocks along nonplanar strike-slip faults crosscutting the Lake Edison Granodiorite, Sierra Nevada, California (Sierran wavy fault) and Lobbia outcrops of the Adamello Batholith in the Italian Alps.

Bayesian inversion for finite fault earthquake source models – II: the 2011 great Tohoku-oki, Japan earthquake
Sarah E. Minson,Mark Simons,James L. Beck,F. Ortega,Junle Jiang,Susan Owen,Angelyn Moore,Asaf Inbal,Anthony Sladen +8 more
TL;DR: In this paper, a fully Bayesian inversion of kinematic rupture parameters for the 2011 Mw 9 Tohoku-oki, Japan earthquake is presented, where most of the slip is concentrated in a depth range of 10-20 km from the trench, and that slip decreases towards the trench with significant displacements at the toe of wedge occurring in just a small region.

Some Comparisons between Mining-induced and Laboratory Earthquakes
TL;DR: In this article, a comparison of stick-slip friction experiments in a large granite sample with mining-induced earthquakes in South Africa and Canada indicates both similarities and differences between the two phenomena.

Earthquake Recurrence in Simulated Fault Systems
TL;DR: In this article, the authors employ a computationally efficient fault system earthquake simulator, RSQSim, to explore the effects of earthquake nucleation and fault system geometry on earthquake occurrence.

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.
