چکیده

Human beings have encountered numerous natural disasters over time, andthe phenomenon of earthquake is one of the most destructive of them.In recent years, the complex behavior of earthquakes in terms of time and space has been investigated using complex networks, which has enabled us to know the global characteristics of this phenomenon. Studies on the earthquakes using the network method are based on how the network is constructed. In this paper, by constructing the network, the spatio-temporal recurrence of earthquakes which occurred in the Zagros region and were recorded at all broadband and short-period stations of the Iranian Seismological Center (ISC, http://irsc.ut.ac.ir) are subject to statistical review. The results showed that in the Zagros area the spatial recurrenceis about 0.020 km, and the time recurrencefor all magnitudethresholds issimilar topower relationship ( ) witha = -0.9.
