Feature of topological properties in an earthquake network

초록

Earthquake network is investigated by considering the volume resolution and the temporal causality. We perform the numerical computations for network metrics from seismic time series data taken in Japan. For our case, we mainly treat the feature of the topological properties via various statistical quantities such as the characteristic path length, the average clustering coefficient, the small-worldness, the cost efficiency, the global efficiency, the modularity, and the assortativity. The universal and irregular properties of statistical quantities in earthquake network do not find unambiguously, but it may be inferred that these topological properties improve by implementing the method and its technique from registered data of earthquake networks.
