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.

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.

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

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

Modeling Exact Frequency-Energy Distribution for Quakes by a Probabilistic Cellular Automaton
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 ...

Earth and Space Science, 2023 Seismic swarms are defined as a group of earthquakes occurring very close in time and space but without any distinctively large event triggering their occurrence. Up to now no simple law has been found to describe the swarm occurrence rate.

ON PROPER TIME OF THE SOURCE OF A STRONG EARTHQUAKE
Геодинамика и тектонофизика, 2023 The physics of earthquakes was contriubuted to by the concept of proper time of the source of a strong earthquake, which is different from universal (calendar) time. The earlier idea of proper time was implicit and has been considered only in relation to

Earth, Planets and Space, 2020 We infer the postseismic deformation mechanisms following the 2011 Tohoku megathrust earthquake via an analysis of onshore geodetic observations. We focus on the temporal decay characteristics of postseismic deformation using continuous time-series data ...
