Statistical Modeling of the Seismic Moments via Mathai Distribution

Entropy (Basel). 2022 May 14;24(5):695. doi: 10.3390/e24050695.

Abstract

Mathai's pathway model is playing an increasingly prominent role in statistical distributions. As a generalization of a great variety of distributions, the pathway model allows the studying of several non-linear dynamics of complex systems. Here, we construct a model, called the Pareto-Mathai distribution, using the fact that the earthquakes' magnitudes of full catalogues are well-modeled by a Mathai distribution. The Pareto-Mathai distribution is used to study artificially induced microseisms in the mining industry. The fitting of a distribution for entire range of magnitudes allow us to calculate the completeness magnitude (Mc). Mathematical properties of the new distribution are studied. In addition, applying this model to data recorded at a Chilean mine, the magnitude Mc is estimated for several mine sectors and also the entire mine.

Keywords: completeness magnitude; parametric statistics; seismic moments; superstatistics.
