Resumen
The problem of universality of critical exponents in complex networks is studied based on networks built from seismic data sets. Using two data sets corresponding to Chilean seismicity (northern zone, including the 2014 M-w = 8.2 earthquake in Iquique; and central zone without major earthquakes), directed networks for each set are constructed. Connectivity and betweenness centrality distributions are calculated and found to be scale free, with respective exponents gamma and delta. The expected relation between both characteristic exponents, delta > (y+1)/2, is verified for both data sets. However, unlike the expectation for certain scale-free analytical complex networks, the value of S is found to be non-universal. (C) 2017 Elsevier B.V. All rights reserved.
