“Aftershock Faults” and What They Could Mean for Seismic Hazard Assessment [PDF]
The Seismic Record, 2023 We study stress‐loading mechanisms for the California faults used in rupture forecasts. Stress accumulation drives earthquakes, and that accumulation mechanism governs recurrence.

Lagrangian formulation of Omori’s law and analogy with the cosmic Big Rip [PDF]
The European Physical Journal C, 2020 A recent model predicting Omori’s law giving the number of aftershocks per unit time following an earthquake involves a differential equation analogous to the Friedmann equation of cosmology. The beforeshock phase is analogous to an accelerating universe

Aftershock production rate of driven viscoelastic interfaces [PDF]
, 2014 We study analytically and by numerical simulations the statistics of the aftershocks generated after large avalanches in models of interface depinning that include viscoelastic relaxation effects.

Relation between stress heterogeneity and aftershock rate in the rate-and-state model [PDF]
, 2006 We estimate the rate of aftershocks triggered by a heterogeneous stress change, using the rate-and-state model of Dieterich [1994].We show that an exponential stress distribution Pt(au) ~exp(-tautau_0) gives an Omori law decay of aftershocks with time ~1/

Self-organization of spatio-temporal earthquake clusters [PDF]
Nonlinear Processes in Geophysics, 2000 Cellular automaton versions of the Burridge-Knopoff model have been shown to reproduce the power law distribution of event sizes; that is, the Gutenberg-Richter law.

A Study of the Unified Scaling Law of Earthquakes in the Taiwan Region
Terrestrial, Atmospheric and Oceanic Sciences, 2008 The unified scaling law (also called the BCDS model), merges: (1) Omori¡¦s Law, (2) Gutenberg-Richter¡¦s law, and (3) the geometrical fractal distribution of epicenters, all of which, in combination, investigate the occurrence of earthquakes from a ...

Properties of Foreshocks and Aftershocks of the Non-Conservative SOC Olami-Feder-Christensen Model: Triggered or Critical Earthquakes? [PDF]
, 2003 Following Hergarten and Neugebauer [2002] who discovered aftershock and foreshock sequences in the Olami-Feder-Christensen (OFC) discrete block-spring earthquake model, we investigate to what degree the simple toppling mechanism of this model is ...

Equivalence of the train model of earthquake and boundary driven Edwards-Wilkinson interface
, 2013 A discretized version of the Burridge-Knopoff train model with (non-linear friction force replaced by) random pinning is studied in one and two dimensions.

A neural encoder for earthquake rate forecasting
Scientific Reports, 2023 Forecasting the timing of earthquakes is a long-standing challenge. Moreover, it is still debated how to formulate this problem in a useful manner, or to compare the predictive power of different models.
