Nonextensive triplet in geological faults system

Abstract

The San Andreas fault (SAF) in the USA is one of the most investigated self-organizing systems in nature. In this paper, we studied some geophysical properties of the SAF system in order to analyze the behavior of earthquakes in the context of Tsallis's q--Triplet. To that end, we considered 134,573 earthquake events in magnitude interval 2≤ m<8, taken from the Southern Earthquake Data Center (SCEDC, 1932 - 2012). The values obtained ("q--Triplet"\qstat,qsen,qrel\) reveal that the qstat--Gaussian behavior of the aforementioned data exhibit long-range temporal correlations. Moreover, qsen exhibits quasi-monofractal behavior with a Hurst exponent of 0.87.
