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:

Stochastic finite-fault simulations of the 2011 Tohoku, Japan, earthquake
TL;DR: In this paper, the authors performed stochastic finite-fault simulations for the moment magnitude (M ) 9.0 11 March 2011 Tohoku earthquake at KiK-net sites using the EXSIM algorithm.
Effects of supershear rupture speed on the high-frequency content of S waves investigated using spontaneous dynamic rupture models and isochrone theory
Andrea Bizzarri,Paul Spudich +1 more
TL;DR: In this paper, it was shown that crack tips governed by friction laws, including slip weakening, rate-and state-dependent laws, and thermal pressurization of pore fluids, propagating at supershear speed have slip velocity functions with reduced high-frequency content compared to crack tips traveling at subshear speeds.

A dynamic model of the frequency-dependent rupture process of the 2011 Tohoku-Oki earthquake
TL;DR: In this paper, the authors presented a 2D dynamic rupture model that provides a physical interpretation of the key features of the 2011 Tohoku-Oki earthquake rupture, and derived quantitative constraints on the ratio of shallow versus deep radiation from teleseismic back-projection source imaging.

“Prediction” of strong ground motion for the 1989 Loma Prieta earthquake using empirical Green's functions
TL;DR: In this paper, a suite of accelerograms are synthesized for five sites 40 to 80 km from the nearest fault rupture from 25 different source models that might have been considered prior to the occurrence of the Loma Prieta earthquake.

Pseudotachylytes and earthquake source mechanics
TL;DR: In this paper, the authors show that in the case of large exposures of pseudotachylyte-bearing faults, such as the glacier-polished outcrops in the Adamello massif (Southern Alps, Italy), they might constrain several earthquake source parameters by linking field studies with microstructural observations, high-velocity rock friction experiments, modeling of the shear heating and melt flow, and dynamic rupture models.

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.
