Investigate of Iran Recurrence Earthquakes by the Network

Abstract

Human beings have encountered numerous natural disasters over time, that the earthquake phenomenon is one of the most damaging of all and has a very complex nature. Earthquakes manifest spatio-temporal complex behavior that can be studied using complex networks, which enabled us to recognize the global features of Earthquake. 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 occurring in the Zagros region, which is recorded at all the 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 spatio recurrence is about 0.020 km, and the time recurrence for all the thresholds of magnitude is similar to power relationship (1⁄Tα) with a α =-0.9 .
