Abstract
We investigate the dynamical behavior of aftershocks in earthquake networks, and the earthquake network calculated from a time series is constructed by contemplating cell resolution and temporal causality. We attempt to connect an earthquake network using relationship between one main earthquake and its aftershocks from seismic data of California. We mainly examine some topological properties of the earthquake such as the degree distribution, the characteristic path length, the clustering coefficient, and the global efficiency. Our result cannot presently determine the universal scaling exponents in statistical quantities, but the topological properties may be inferred to advance and improve by implementing the method and its technique of networks. Particularly, it may be dealt with a network issue of convenience and of importance in the case how large networks construct in time to proceed on earthquake systems.

Summary
Scientists have treated emerging problems in order to cover the basic concept and the important principle or clearly describe the scientific phenomenon. Small-world and scale-free network models [17] [18] have been studied widely in various applications of these scientific fields and played a crucial role in understanding complex phenomena [19] [20] [21]. The Omori-Utsu law [25] has analyzed the calculation of earthquakes by a theoretical formula, and the frequency of aftershocks has decayed in a power law. Nanjo et al [30] have investigated the seismicity modeled by the Gutenberg-Richter law and the Omori-Utsu law in M6.5 quake of Kumamoto 2016. They speculated the reduction of the occurrence of larger shocks causing the notable increase in the b value and the large p value
