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:

Hematite fault rock thermochronometry and textures inform fault zone processes
TL;DR: In this paper, the authors used (U-Th)/He (He) thermochronometry to characterize fault-coated hematite surfaces from exhumed damage zones in the seismically active Wasatch fault zone (WFZ), UT and Painted Canyon fault (PCF) paralleling the southern San Andreas fault, Mecca Hills, CA.

Earthquake Ground Motion and 3D Georgia Basin Amplification in Southwest British Columbia: Deep Juan de Fuca Plate Scenario Earthquakes
TL;DR: In this paper, the authors investigate the effects of the Georgia basin structure on ground shaking in Greater Vancouver, British Columbia, Canada, by modeling 3D long-period ground motions for large (M w ǫ 6.8) scenario earthquakes.

Friction properties and deformation mechanisms of halite(-mica) gouges from low to high sliding velocities
L. Buijze,L. Buijze,L. Buijze,André Niemeijer,Raehee Han,Toshihiko Shimamoto,Christopher J. Spiers +6 more
TL;DR: In this paper, the evolution of friction and corresponding operating deformation mechanisms in analog gouges deformed from low to high slip rates were investigated in upper crustal quartzitic fault rocks, at conditions accessible in the laboratory.

Geodetic Observations of Weak Determinism in Rupture Evolution of Large Earthquakes.
TL;DR: Early rupture metrics are investigated to determine whether observational data support deterministic rupture behavior, and it is found that while the earliest metrics are not enough to infer final earthquake magnitude, accurate estimates are possible within the first tens of seconds, prior to rupture completion, suggesting a weak determinism.

Kinematic Inversion of Strong‐Motion Data Using a Gaussian Parameterization for the Slip: Application to the 2008 Iwate–Miyagi, Japan, Earthquake
TL;DR: In this article, a finite-element approach based on a Delaunay triangulation of the fault plane is proposed for estimating the distribution of the final slip and the rupture velocity on the fault planes from the inversion of strong-motion records.

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.
