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.

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 ...

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

Gutenberg–Richter B-Value Time Series Forecasting: A Weighted Likelihood Approach
Forecasting, 2021 We introduce a novel approach to estimate the temporal variation of the b-value parameter of the Gutenberg–Richter law, based on the weighted likelihood approach.

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 ...

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 ...

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.

Detection of Jovian seismic waves: a new probe of its interior structure [PDF]
, 2011 Knowledge of Jupiter's deep interior would provide unique constraints on the formation of the Solar System. Measurement of its core mass and global composition would shed light on whether the planet formed by accretion or by direct gravitational collapse.
