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:

Hybrid k-squared source model for strong ground motion simulations: Introduction
TL;DR: In this article, the authors proposed a hybrid kinematic k-squared source model based on a set of subsources, scaled to provide the k-square slip distribution, which combines the integral approach at low frequencies and the composite approach at high frequencies, based on the summation of ground motion contributions from the subsources.

Properties of inelastic yielding zones generated by in-plane dynamic ruptures—II. Detailed parameter-space study
TL;DR: In this article, a detailed parameter-space study on the properties of yielding zones generated by 2D in-plane dynamic ruptures on a planar fault with different friction laws and parameters, different initial stress conditions, different rock cohesion values, and different contrasts of elasticity and mass density across the fault.

Seismic hazard assessment for a characteristic earthquake scenario: an integrated probabilistic deterministic method
TL;DR: In this article, the authors extended the psha approach to the case of a characteristic earthquake scenario associated with an active fault and proposed an approach integrating psha with a high-frequency deterministic technique for the prediction of peak and spectral ground motion parameters.

Focal mechanism determination and identification of the fault plane of earthquakes using only one or two near-source seismic recordings
Bertrand Delouis,Denis Legrand +1 more
TL;DR: In this paper, a waveform inversion scheme was developed to explore the resolving power of one or two seismic recordings at short epicentral distance for the determination of focal mechanisms and the identification of the fault plane of earthquakes.

Replication of apparent nonlinear seismic response with linear wave propagation models
TL;DR: It is necessary to understand ground-motion amplification by sediment, defined as the ratio of ground motions at sediment sites to those at rock sites, to predict seismic loadings for earthquake engineering and shows that linear wave propagation can explain observed (apparently nonlinear) sediment responses.

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.
