TLDR
In this paper, the authors present a theoretical framework for earthquake cycles based on calculating the stress changes caused by one event and assessing where and what mechanism of earthquakes these changes may promote, which is different from investigating the dynamic rupture growth requiring the reconstruction of the spatiotemporal evolution of the stress on the fault plane.Abstract:
Publisher Summary This chapter discusses the recent developments in understanding how earthquakes interact with each other. The new theoretical framework for earthquake cycles is based on calculating the stress changes caused by one event and assessing where and what mechanism of earthquakes these changes may promote. For studying such stress interaction, the computation of the stress field outside a rupturing fault is analyzed. This is different from investigating the dynamic rupture growth requiring the reconstruction of the spatiotemporal evolution of the stress on the fault plane. The chapter discusses the theoretical background of earthquake sequences and reviews some of the simple examples that allowed stress coupling concepts to be accepted. The success of simple stress modeling led to the introduction of several modifications, adaptations, and refinements of the ideas.read more

TL;DR: In this article, the authors argue that key features of thrust earthquake triggering, inhibition, and clustering can be explained by Coulomb stress changes, which illustrate by a suite of representative models and by detailed examples.

Forecasting the evolution of seismicity in southern California: Animations built on earthquake stress transfer
TL;DR: In this article, a forecast model was developed to reproduce the distribution of main shocks, aftershocks and surrounding seismicity observed during 1986-2003 in a 300 × 310 km area centered on the 1992 M = 7.3 Landers earthquake.

Earthquake triggering by static, dynamic, and postseismic stress transfer
TL;DR: In this paper, the authors used static Coulomb stress changes associated with earthquake slip to explain aftershock distributions, earthquake sequences, and the quiescence of broad, normally active regions following large earthquakes.

Characterization of Fault Zones
TL;DR: There are currently three major competing views on the essential geometrical, mechanical, and mathematical nature of faults as discussed by the authors : the standard view is that faults are (possibly segmented and heterogeneous) Euclidean zones in a continuum solid.

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.
