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:

Investigation of the rupture process of the 28 June 1992 Landers earthquake utilizing TERRAscope
TL;DR: In this paper, the authors used a forward, point-source summation technique to model the Landers mainshock and found that the distribution and amplitude of slip at the surface matched the observed surface slip and provided a very good level of fit to the seismic data.

Sergio Ruiz,Sergio Ruiz,Raul Madariaga,Maximiliano Astroza,G. Rodolfo Saragoni,M. Lancieri,Christophe Vigny,Jaime Campos +7 more
TL;DR: In this paper, the authors used the continuous GPS (cGPS) records to invert for the kinematic rupture process using an elliptic curve, which is used in the 2010 Maule earthquake.

The seismic microzonation of the city of Catania (Italy) for the maximum expected scenario earthquake of January 11, 1693
Salvatore Grasso,Michele Maugeri +1 more
TL;DR: In this article, a geotechnical zonation of the subsoil of the city of Catania (Italy) suggests a high vulnerability of the physical environment added to site amplification of the ground motion phenomena, and the ground response analysis at the surface, in terms of time history and response spectra, was obtained by some 1D equivalent linear models and by a 2D linear model, using a design scenario earthquake as input at the conventional bedrock.

Digital image correlation to analyse stick-slip behaviour of tyre tread block
TL;DR: In this paper, the sliding motion of a rubber sample was studied on a glass plate and the local sliding velocity field of the contact area was calculated by means of Digital Image Correlation and compared to the measured friction force.

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.
