Mathematical Theory of Seismic Activity and Its Specific Cases: Gutenberg–Richter Law, Omori Law, Roll-Off Effect, and Negative Binomial Distribution [PDF]
EntropyWe discuss a model of seismic activity that is based on the concept of energy in a cluster of sources of seismic activity. We show that specific cases of the studied model lead to the Gutenberg–Richter relationship and the Omori law. These laws are valid

On the Omori Law in the Physics of Earthquakes
Applied Sciences, 2022 This paper proposes phenomenological equations that describe various aspects of aftershock evolution: elementary master equation, logistic equation, stochastic equation, and nonlinear diffusion equation.

Interpretation of the Omori law [PDF]
Izvestiya, Physics of the Solid Earth, 2016 The well-known Omori law is represented in the form of the differential equation describing the evolution of the aftershock activity. The interpretation of the evolution equation is suggested.

Frontiers in Earth Science, 2022 Strong to great earthquakes considerably weaken the structural strength of the subsurface strata and civil constructions. The occurrence of Mw ≥ 5 aftershocks further contributes to the loss of human lives and damage to property.

Aftershocks and Fluctuating Diffusivity [PDF]
Entropy, 2023 The Omori-Utsu law shows the temporal power-law-like decrease of the frequency of earthquake aftershocks and, interestingly, is found in a variety of complex systems/phenomena exhibiting catastrophes.

Correlations and Omori law in spamming [PDF]
EPL (Europhysics Letters), 2008 The most costly and annoying characteristic of the e-mail communication system is the large number of unsolicited commercial e-mails, known as spams, that are continuously received.

Modeling Exact Frequency-Energy Distribution for Quakes by a Probabilistic Cellular Automaton [PDF]
Entropy, 2023 We develop the notion of Random Domino Automaton, a simple probabilistic cellular automaton model for earthquake statistics, in order to provide a mechanistic basis for the interrelation of Gutenberg–Richter law and Omori law with the waiting time ...

New Empirical Tests of the Multifractal Omori Law for Taiwan [PDF]
Bulletin of the Seismological Society of America, 2011 We report new tests of the linear dependence of the p ‐value of aftershock sequences on the magnitude M m of the triggering event for the Taiwan earthquake catalog.

Power-law relaxation in a complex system: Omori law after a financial market crash. [PDF]
Physical Review E, 2001 We study the relaxation dynamics of a financial market just after the occurrence of a crash by investigating the number of times the absolute value of an index return is exceeding a given threshold value. We show that the empirical observation of a power

Partial Ruptures, Cascading Multi‐Fault Ruptures, and Aftershocks in 2D Random Fault Network
Geophysical Research LettersThe Gutenberg‐Richter law for the distribution of earthquake magnitude and the Omori law for the decay of aftershocks are two universal laws in seismicity. Although numerical models have been developed to reproduce these laws, they sometimes produce many
