Popis: We analyse four seismic areas in Brazil using a nonextensive model and the data from the Brazilian Seismic Bulletin between 1720 and 2013. Two of those regions are contrasting zones, while the other two are dominated by seismic active faults. We notice that intraplate seismic zones present q-values similar to others fault zones, but the adjustment in contrast areas results in higher values for this parameter. The results reveal the nonextensive approach adjusts robustly also in case of intraplate earthquakes, showing that the Tsallis formalism is unquestionably a powerful tool to the analysis of this phenomenon.
