Abstract
In this letter we aim to describe the seismic activity of the Rigan earthquake 2010, using the virtual seismometer (ViS) technique. By defining avalanche-type dynamics on top of the ViS complex network, we show that the seismic activity is strongly intermittent, and is cyclic as seen in the natural situations. This model is based on avalanches during which signals, as a simulation of the real seismic signals, travel between regions that already were connected on the ViS network. This network is mainly characterized by a power-law distribution of the degree of nodes with an exponent . The branching ratio inside and between avalanches reveals that the system is in a critical state showing power-law behavior for the distribution function of the mass, the duration and the size of the avalanches, the critical exponent of the latter being . We find a considerable correlation between the dynamical Green function and the nodes centralities, showing that the simulated signals are close to the real seismic signals, from which we constructed the complex network.
