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:

Rapid Acceleration Leads to Rapid Weakening in Earthquake-Like Laboratory Experiments
TL;DR: The spontaneous evolution of strength, acceleration, and velocity indicates that seismically determined earthquake parameters can be used to estimate the intensity of the energy release during an earthquake, and experiments indicate that high acceleration imposed by the earthquake’s rupture front quickens dynamic weakening by intense wear of the fault zone.

Visualizing stick–slip: experimental observations of processes governing the nucleation of frictional sliding
TL;DR: In this paper, the authors review experimental studies of dynamical aspects of frictional sliding and focus mainly on recent advances in real-time visualization of the real area of contact along large spatially extended interfaces and the importance of rapid fracture-like processes that appear at the onset of Frictional instability.

On the Propagation of Slip Fronts at Frictional Interfaces
TL;DR: In this article, a dynamic initiation of sliding at planar interfaces between deformable and rigid solids is studied with particular focus on the speed of the slip front, and an energetic criterion is proposed to uniquely associate, independently on the direction of propagation and its acceleration, slip front velocity with the relative rise of the energy density at the slip tip.

What We Can and Cannot Learn about Earthquake Sources from the Spectra of Seismic Waves
TL;DR: In this article, it was shown that the slip velocity on the fault is the real parameter that controls the strength of the highfrequency radiation; it can be directly determined from acceleration spectra by fitting their high-frequency level.

Application of an iterative least-squares waveform inversion of strong-motion and teleseismic records to the 1978 Tabas, Iran, earthquake
TL;DR: In this article, an iterative least squares technique is used to simultaneously invert the strong-motion records and teleseismic P waveforms for the 1978 Tabas, Iran, earthquake to deduce the rupture history.

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.
