Correlations and Omori law in Spamming [PDF]

open access: yesEPL (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.

Magnitude-Dependent Omori Law: Empirical Study and Theory [PDF]

open access: yesJournal of Geophysical Research: Solid Earth, 2004
We propose a new physically-based ``multifractal stress activation'' model of earthquake interaction and triggering based on two simple ingredients: (i) a seismic rupture results from activated processes giving an exponential dependence on the local ...

Aftershocks and Fluctuating Diffusivity [PDF]

open access: yesEntropy, 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.

Modeling Exact Frequency-Energy Distribution for Quakes by a Probabilistic Cellular Automaton [PDF]

open access: yesEntropy, 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 ...

On the Omori Law in the Physics of Earthquakes

open access: yesApplied 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.

Mathematical Theory of Seismic Activity and Its Specific Cases: Gutenberg–Richter Law, Omori Law, Roll-Off Effect, and Negative Binomial Distribution [PDF]

open access: yesEntropy
We 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

Analysis of the b, p values, and the fractal dimension of aftershocks sequences following two major earthquakes in central Himalaya [PDF]

open access: yesHeliyon
On April 25 of 2015, earthquake of 7.6 ML struck the central Himalayan region having epicenter at Barpak village in the Gorkha district of Nepal. The event was followed by 7.0 ML earthquake known as Dolakha earthquake, epicenter on the border of Dolakha ...

Andrade, Omori and Time-to-failure Laws from Thermal Noise in Material Rupture [PDF]

open access: yesPhysical Review E, 2003
Using the simplest possible ingredients of a rupture model with thermal fluctuations, we provide an analytical theory of three ubiquitous empirical observations obtained in creep (constant applied stress) experiments: the initial Andrade-like and Omori ...

High probability of successive occurrence of Nankai megathrust earthquakes [PDF]

open access: yesScientific Reports, 2023
Great earthquakes along the Nankai megathrust in south-western Japan feature in the top priority list of Japan’s disaster management agenda. In May 2019, an alert system was incepted to issue public warnings when the probability of an earthquake ...

Earthquake Statistical Parameters Analysis and Regional Variations of March 02, 2017 Adıyaman-Samsat Earthquake (Ml = 5.7) by Using its Aftershocks

open access: yesDoğal Afetler ve Çevre Dergisi, 2022
In this study, using the aftershocks that occurred after the March 02, 2017 Adıyaman-Samsat Earthquake (Ml = 5.7) statistical analyzes of b-value and aftershock decay parameter p-value were performed.
