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:

Rupture dynamics of a planar fault in a 3D elastic medium: Rate- and slip-weakening friction
Eiichi Fukuyama,Raul Madariaga +1 more
TL;DR: In this article, a boundary integral equation method (BIEM) is proposed to model the spontaneous propagation of rupture on a planar fault embedded in a homogeneous elastic medium, which is very compact and fast in computation, so that they are able to study the effect of different slip-and rate-dependent friction laws on dynamic shear fault propagation.

Local Tsunamis and Earthquake Source Parameters
TL;DR: In this article, the authors established the relationship among earthquake source parameters and the generation, propagation, and run-up of local tsunamis by using elastic dislocation theory for which the displacement field is dependent on the slip distribution, fault geometry, and elastic response and properties of the medium.

Ductile creep, compaction, and rate and state dependent friction within major fault zones
TL;DR: In this article, the authors show that the shear traction on major strike-slip faults during earthquakes is much lower than that expected on a frictionally sliding surface in equilibrium with hydrostatic pressure.

Rupture Kinematics of the 2005 Mw 8.6 Nias–Simeulue Earthquake from the Joint Inversion of Seismic and Geodetic Data
A. Ozgun Konca,Vala Hjörleifsdóttir,Teh-Ru Alex Song,Jean Philippe Avouac,Donald V. Helmberger,Chen Ji,Kerry Sieh,Richard W. Briggs,Aron J. Meltzner +8 more
TL;DR: In this article, a joint analysis of seismic data and near-field static co-seismic displacements was performed to assess the source character-istics of the 2005 Nias-Simeulue earthquake, which was caused by rupture of a portion of the Sunda megathrust offshore northern Sumatra.

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.
