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:

Dynamic Earthquake Ruptures in the Presence of Material Discontinuities
TL;DR: In this article, the authors present three specific numerical investigations of the aforementioned rupture phenomenon associated with material contrasts at the fault and demonstrate that bimaterial frictional interfaces are attractive trajectories of rupture propagation, and ruptures tend to migrate to material interfaces and becoming self-sustained slip pulses for wide ranges of conditions.

Fault heterogeneity and earthquake scaling
A. Hetherington,Sandy Steacy +1 more
TL;DR: In this paper, the authors investigate whether stress drop is independent of earthquake size and find that when the range of heterogeneity is low, the scaling approach that of constant stress drop approaches that of stress drop.
4652 - modes of dynamic rupture on interfaces with nonlinear rate and state friction laws
TL;DR: In this article, the authors considered the nonlinear rate and state friction laws in which the frictional strength (or resistance) of the interface depends on the local sliding rate (or relative particle velocity) V and a state variable The state variable incorporates dependence on the history of slip and describes the evolving properties of the microscopic contacts on the interface.

Parametric analysis of the elastohydrodynamic lubrication efficiency on induced seismicity
Chiara Cornelio,Marie Violay +1 more
TL;DR: In this article, the authors performed a parametric analysis of the elastohydrodynamic fault lubrication mechanism to assess its efficiency during fluid-induced earthquakes, and the efficiency of the mechanism was measured with the dimensionless Sommerfeld number S.

Approximate Stochastic Self-Similarity of Envelopes of High-Frequency Teleseismic P -Waves from Large Earthquakes
TL;DR: In this article, the authors applied variogram and spectral analysis to time histories of P-wave envelopes (squared-amplitude or instant-power signals) in six HF bands of 1-Hz width.

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.
