Investigating the universal character of k–M slope in earthquake catalogs from the Visibility Graph method [PDF]
Scientific ReportsThe b-value of the Gutenberg–Richter law, which describes the magnitude-frequency relationship of seismicity, is the most widely investigated statistical parameters derived from the study of earthquake catalogs.

Characteristics of the foreshock occurrence for Mj3.0 to 7.2 shallow onshore earthquakes in Japan
Earth, Planets and Space, 2022 We use the Japan Meteorological Agency (JMA) earthquake catalogue from January, 2001 to February, 2021 to investigate the spatiotemporal foreshock occurrence for shallow (within 30 km depth) onshore earthquakes (Mj3.0 to 7.2). We find clear peaks for the

Statistical and clustering analysis of microseismicity from a Saskatchewan potash mine
Frontiers in Applied Mathematics and Statistics, 2023 Microseismicity is expected in potash mining due to the associated rock-mass response. This phenomenon is known, but not fully understood. To assess the safety and efficiency of mining operations, producers must quantitatively discern between normal and ...

Incorporating Foreshocks in an Epidemic-like Description of Seismic Occurrence in Italy
Applied Sciences, 2023 The Epidemic Type Aftershock Sequence (ETAS) model is a widely used tool for cluster analysis and forecasting, owing to its ability to accurately predict aftershock occurrences.

Geophysical Research Letters, 2023 Earth's crust is continuously subjected to oscillatory stress perturbations due to the solid Earth and ocean tides. The seismic response to such stress modulations carries information on earthquake physics and crustal properties.

Axioms, 2023 The main purpose of this paper was to, for the first time, analyse the spatiotemporal features of the background seismicity of Northern Algeria and its vicinity, as identified by different declustering methods (specifically: the Gardner and Knopoff ...

Tsallis q-Statistics in Seismology
Entropy, 2023 Non-extensive statistical mechanics (or q-statistics) is based on the so-called non-additive Tsallis entropy. Since its introduction by Tsallis, in 1988, as a generalization of the Boltzmann–Gibbs equilibrium statistical mechanics, it has steadily gained ground as a suitable theory for the description of the statistical properties of non-equilibrium ...

Temporal distribution characteristics of earthquakes in Taiwan, China
Frontiers in Earth Science, 2023 The characteristics of seismic temporal distribution represent an important basis for earthquake prediction and seismic hazard analysis. In this paper, based on the seismic catalogs in Taiwan, and using Poisson (exponential distribution), Gamma ...
