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:

Two‐dimensional numerical modeling for near source strong ground motions of the Chelungpu fault during the 1999 Chi‐Chi Taiwan earthquake
TL;DR: In this paper, two-dimensional numerical modeling based on the finite element method is employed to simulate near fault tip strong motion records of the Chi-Chi Earthquake on September 21, 1999, in order to examine the kinematics of earthquake faulting and near field wave propagation properties.

Constraints on rupture speed of the 2001 MS 8.1 West Kunlun Mountain Pass earthquake by co-seismic surface rupture slip displacements based on the slip-weakening mechanism with frictional undershoot involved
Bao-ping Shi,Yong Yang +1 more
TL;DR: In this paper, the authors estimate the rupture speed on the main faulting segment with a long straight fault trace on the surface based on a simple slip-weakening rupture model, in which the frictional overshoot or undershoot are involved in consideration of energy partition during the earthquake faulting.

On Scaling of Earthquake Rise‐Time Estimates
A. A. Gusev,D. V. Chebrov +1 more
TL;DR: In this article, the scaling behavior of rise times Tr determined within earthquake source inversions that used strong-motion data is determined using estimates as accumulated in the SRCMOD database; this agrees with the assumption of self-similarity of earthquake ruptures.

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.
