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:

Rise time of the 2018 MW 6.4 Hualien earthquake revealed by source time functions: A restrictive estimation of static stress drop
TL;DR: In this article , the authors proposed a method to confine the estimation of static and dynamic stress drop through ∆σd to 2∆σs and 2πσd−2μEgM0, respectively.

Earthquake ground-motion parameters at stiff sites in Addis Ababa, Ethiopia
B. Yoseph,G. V. Ramana +1 more
TL;DR: In this paper, the authors developed ground motion relations for peak ground acceleration and response spectra (Pseudo-acceleration, 5% damped) for stiff sites in Addis Ababa (near surface shear-wave velocity, β ≥ 760 m/s), as a function of moment magnitude (M) >5 and closest distance to the fault rupture (<100 km) considering uncertainties in seismological parameters.
Earthquake Early Warning and the Physics of Earthquake Rupture
TL;DR: In this paper, the ElarmS earthquake early warning system has been tested on the Northern California and Berkeley Digital Seismic Networks and the results of the experiments indicate that the early slip on a fault also scales with magnitude and suggest that earthquakes are not entirely self-similar.

Observation‐Constrained Multicycle Dynamic Models of the Southern San Andreas and the Northern San Jacinto Faults: Addressing Complexity in Paleoearthquake Extent and Recurrence With Realistic 2D Fault Geometry
TL;DR: In this article , the authors simulate physics-based multicycle dynamic models of the San Andreas fault (Carrizo through San Bernardino sections) and the San Jacinto fault (Claremont and Clark strands).
Estimation of near-fault strong ground motions for key engineering structures
TL;DR: In this paper, a new source spectral model is developed from Brune's ω 2 model and Atkinson's two-comers model, and the spectral differences between small and strong earthquakes are described not only in amplitude and comer periods, but also in the shapes that were revealed by the recordings.

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.
