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:

Earthquake Ground-Motion Prediction Equations for Eastern North America
Gail M. Atkinson,David M. Boore +1 more
TL;DR: In this article, a stochastic finite-fault model was used to predict ground motion for hard-rock and soil sites in eastern North America (ENA), including estimates of their aleatory uncertainty (vari- ability).

Displacement and Geometrical Characteristics of Earthquake Surface Ruptures: Issues and Implications for Seismic-Hazard Analysis and the Process of Earthquake Rupture
TL;DR: In this article, the authors present a series of historical earthquakes for which in-vestigators have constructed maps of earthquake rupture traces accompanied by de- scriptions of the coseismic slip observed along the fault strike.

The physics of earthquakes
Hiroo Kanamori,Emily E. Brodsky +1 more
TL;DR: In this article, a discussion of stress in the crust followed by an overview of earthquake phenomenology, focusing on the parameters that are readily measured by current seismic techniques is presented. But this simple picture is far from complete, as earthquakes are sometimes triggered by other large earthquakes thousands of kilometres away.

Stochastic Finite-Fault Modeling Based on a Dynamic Corner Frequency
TL;DR: In this article, a dynamic corner frequency approach is introduced to model the ground motion from the entire fault, where the corner frequency is a function of time and the rupture history controls the frequency content of the simulated time series of each subfault.

Predicting the endpoints of earthquake ruptures.
TL;DR: It is shown that about two-thirds of the endpoints of strike-slip earthquake ruptures are associated with fault steps or the termini of active fault traces, and that there exists a limiting dimension of fault step above which earthquake rupture do not propagate and below which rupture propagation ceases only about 40 per cent of the time.

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.
