AB: Geological fault systems, as the San Andreas fault (SAF) in USA, constitute typical examples of self-organizing systems in nature. In this work, we have considered some geophysical properties of the SAF system to test the viability of the nonextensive model for earthquakes developed in [R. Silva, G.S. França, C. Vilar, J.S. Alcaniz, Phys. Rev. E 73 (2006) 026102]. To this end, we have selected earthquake events, ranging in the magnitude interval 2 < m < 8, from the National Earthquake International Center catalogs (NEIC, 2004 - 2006) and the Bulletin of the International Seismological Centre (ISC, 1964 - 2003). For values of the nonextensive parameter q ~ 1.68, it is shown that the energy distribution function deduced in above reference provides an excellent fit to the NEIC and ISC SAF data. A brief discussion on a possible influence of the fault mechanisms (reverse, normal or strike-slip) on the predictions of this nonextensive model is also presented.
