Relation between connectivity and coupling in the Chilean subduction
zone: a first approach
Abstract
A time-based complex network analysis on the seismic activity along the
coast of Chile was made. The coast of Chile was divided on windows of
300 km in Latitude, from Arica up to Los Angeles. The window was moved
100 km from north to south. We built a time-based earthquake complex
network, on each window and we studied a directed and undirected complex
network. Assuming a self-similar data network, for the directed network
we found the value of the power-law characteristic exponent γ for the
connectivity probability distribution. For the directed network, we
analyzed the average path length, measured through steps and meters, of
the data set. For each window, we obtained a similar relation between
the value of γ and the average path length. The exponents and values
were evaluated for the data set with the total number of seismic events
with a depth greater than 200 km and of magnitude greater than Mw=3.0.
