The earthquakes network: the role of cell size
The complex network theory is a way to investigate the complex systems with minimum information about their entities and corresponding interactions. There is a growing interest to studying the earthquake phenomena by the method of networks. Several network features characterize the complexity of seismic events. Unfortunately they depend on how we construct the network. Here we study the role of cell size or in other word the resolution on the network properties for the Iran’s seismic data. We have found that all the network topological features vary as a power of the resolution. Furthermore by increasing the resolution, the networks become random and uncorrelated.
