TL;DR: In this paper, the authors present evidence that nonlinearity can be directly observed in acceleration time histories such as those recorded at the Wildlife Refuge and Kushiro Port downhole arrays from the 1987 Superstition Hills, California, and the 1993 Kushiro-Oki, Japan, earthquakes, respectively.

TL;DR: In this article, the authors analyzed 315 dynamic strike-slip rupture models computed up to 5.0 Hz to get a quantitative understanding of the correlation and amplitude distributions of parameters describing the earthquake source, such as slip and rupture velocity.

TL;DR: In this paper, the authors used a 1-D stochastic model for the source models of four earthquakes: the 1979 Imperial Valley, the 1989 Loma Prieta, the 1994 Northridge and 1995 Hyogo-ken Nanbu (Kobe).

TL;DR: In this article, a stochastic model that reproduces the spatial variability and the long-range spatial correlation of the slip distribution of the 1979 Imperial Valley earthquake is presented. But the model does not capture the spatial complexity of earthquake slip or prestress distribution over the fault surface.

TL;DR: In this article, the authors treated K as a multifractal and investigated its scaling and fractality using measured horizontal K data from two locations in the United States, one from a shoreline sandstone near Coalinga, California, and the other from an eolian sandstone.
