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:

Phase-transformation-induced lubrication of earthquake sliding
TL;DR: It is suggested that earthquakes at all depths slide at low frictional resistance by a self-healing pulse mechanism with rapid strength recovery, similar to high-speed friction studies at low pressure.

Improved concept of lithospheric strength and earthquake activity at shallow depths based upon the fan-head dynamic shear rupture mechanism
Boris Tarasov,Mark Randolph +1 more
TL;DR: In this paper, the authors proposed an improved concept of lithospheric strength and earthquake activity at seismogenic depths, based on a recently identified fan-head shear rupture mechanism which can be initiated in intact rocks in the proximity of pre-existing faults.

Rupture process for micro-earthquakes inferred from borehole seismic recordings
TL;DR: In this article, the authors investigate the spatial extent of rupture and variability in fault slip for micro-earthquakes by inverting seismic moment rate functions derived from empirical Green's function deconvolution.
The mechanics of seismic faulting: Recent advances and open issues
TL;DR: In the early 60s, the fracture mechanics was mainly focused on tensile cracks (of prominent importance in engineering problems) and later on shear, antiplane cracks Since these studies consisted in singular problems without friction, their applicability to earthquake events was extremely limited.

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.

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.
