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:

Rupture Directivity of the 2019 ML 6.3 Xiulin (Taiwan) Earthquake Estimated by Near-Field Seismograms: Implications for Source Scaling During Faulting
TL;DR: In this article , the authors deconvolved regional seismograms to derive the azimuth-dependent source time functions for the 2019 Xiulin earthquake in Hualien, Taiwan, and then, rupture directivity analysis was used to estimate the fault parameters, and the results revealed a rupture length of 11.5 km, a source duration of 7.37 s, and a rupture velocity (V r ) of 1.56 km/s, approximately 0.4 times the value of the crustal S-wave velocity.

Size dependence of strength and a model reduction method for frictional dynamical systems failing at multiple length scales
Ahmed Elbanna,Thomas H. Heaton +1 more
TL;DR: In this paper, the authors studied the long term behavior of a 1D spring block model with a rate dependent friction law that fails in repeated episodes of pulse-like ruptures of different sizes.

Scaling theory for the statistics of slip at frictional interfaces
TL;DR: In this paper , the authors argue that disorder is a relevant perturbation to this description and derive scaling relations for avalanches, including a relation between the stress drop and the spatial extension of a slip event, and successfully test these predictions in a minimal model of frictional interfaces.

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.

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.
