TLDR
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.Abstract:
▪ Abstract Earthquake triggering is the process by which stress changes associated with an earthquake can induce or retard seismic activity in the surrounding region or trigger other earthquakes at great distances. Calculations of static Coulomb stress changes associated with earthquake slip have proven to be a powerful tool in explaining many seismic observations, including aftershock distributions, earthquake sequences, and the quiescence of broad, normally active regions following large earthquakes. Delayed earthquake triggering, which can range from seconds to decades, can be explained by a variety of time-dependent stress transfer mechanisms, such as viscous relaxation, poroelastic rebound, or afterslip, or by reductions in fault friction, such as predicted by rate and state constitutive relations. Rapid remote triggering of earthquakes at great distances (from several fault lengths to 1000s of km) is best explained by the passage of transient (dynamic) seismic waves, which either immediately induce ...read more

An integrated perspective of the continuum between earthquakes and slow-slip phenomena
Zhigang Peng,Joan Gomberg +1 more
TL;DR: In this article, a review of slow-slip phenomena suggests that instead there is a continuum between the two types of event, i.e., slow slip, a mechanism by which faults can relieve stress, was thought to be distinct from earthquakes.

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.

Slow slip events and seismic tremor at circum-Pacific subduction zones
TL;DR: A review of slow slip events and related seismic tremor observed at plate boundaries worldwide, with a focus on circum-Pacific subduction zones is presented in this article, where the authors show that slow slip is a common phenomena observed at almost all subduction regions with instrumentation capable of recording it, different frictional properties likely control fast versus slow slip, and the depth range may be related to the thermal properties of the plate interface.

TL;DR: In this article, the authors focus on the short-term prediction and forecasting of tectonic earthquakes and indicate guidelines for utilization of possible forerunners of large earthquakes to drive civil protection actions, including the use of probabilistic seismic hazard analysis in the wake of a large earthquake.

The Mechanics of Earthquakes and Faulting
TL;DR: The connection between faults and the seismicity generated is governed by the rate and state dependent friction laws -producing distinctive seismic styles of faulting and a gamut of earthquake phenomena including aftershocks, afterslip, earthquake triggering, and slow slip events.

Slip instability and state variable friction laws
TL;DR: In this paper, the dependence of the friction force on slip history is described by an experimentally motivated constitutive law where the friction forces are dependent on slip rate and state variables.

Static stress changes and the triggering of earthquakes
TL;DR: In this article, a Coulomb failure criterion was proposed for the production of aftershocks, where faults most likely to slip are those optimally orientated for failure as a result of the prevailing regional stress field and the stress change caused by the mainshock.
