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:

Investigations and new insights on earthquake mechanics from fault slip experiments
Long Hao Dong,Qiao Luo +1 more
TL;DR: In this paper , the authors reviewed the experiment study of fault slip from field experiments, laboratory experiments, and numerical experiments, which helps to provide a clear understanding of earthquake mechanics and showed that there are five main influencing factors in the study of faults and earthquakes: stress, velocity, material, fluid, and temperature.

Velocity-weakening friction as a factor in controlling the frequency-magnitude relation of earthquakes
TL;DR: In this article, a one-dimensional BK mass-spring model in the presence of velocity-weakening friction (in a linear form) is applied to dynamically simulate earthquakes.

Understanding of slip‐weakening and ‐strengthening in a single framework of modeling and its seismological implications
Takehito Suzuki,Teruo Yamashita +1 more
TL;DR: In this article, the authors theoretically study dynamic fault slip taking account of thermoporoelastic effects including inelastic porosity change; the porosity on the fault is assumed to increase inelastically with increasing fault slip.

Physical Processes That Control Strong Ground Motion
TL;DR: In this paper, the main characteristics of strong earthquake ground motion and the main physical processes that control these motions are discussed, and the mathematical basis for a physics-based prediction of strong motion is the representation theorem.

Ten year recurrence time between two major earthquakes affecting the same fault segment
Martin Vallée,Claudio Satriano +1 more
TL;DR: In this article, the authors show that this mechanism can be ineffective at stopping rupture expansion: the 17 November 2013 magnitude 7.8 Scotia Sea earthquake has propagated into a 100 km long zone already ruptured 10 years ago by a magnitude 6.6 earthquake, indicating that the variations of the tectonic stress during the seismic history of the fault are small compared to the stresses dynamically generated by a large earthquake.

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.
