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 this end, we considered 134573 earthquake events in the magnitude interval , taken from the Southern Earthquake Data Center (SCEDC, 1932–2012). The values obtained (“q-Triplet”) reveal that the -Gaussian behavior of the aforementioned data exhibit long-range temporal correlations. Moreover, exhibits quasi-monofractal behavior with a Hurst exponent of 0.87.
