Nonextensive analysis of seismic sequences

By using the Tsallis-based nonextensive statistics, the analysis of the magnitude distribution of several seismic catalogues in Italy was performed. The analysis shows similar values for the q-value, in good agreement with those obtained for other seismo-tectonic settings e.g. Silva et al. (2006) 2] and Vilar et al. (2007) 3]]. In particular, it is shown that the volcano seismicity is characterized by slightly lower values for q. The latter results could provide hints for further investigation in discriminating tectonic from volcanic seismicity.
