spectral analysis of 12november 2017 and 25november 2018 earthquake in western iran

The 12 november 2017 ezgeleh earthquake, mw=7.3, occurred at 18:18:24 gmt, in western of iran (figure 1). seismic source parameters were determined by using teleseismic data and body-wave spectrum. data was provided in the sac format of the iris site, which includes 31 stations at a distance 30 to 90 degrees. p phase was selected on the vertical component and body-wave spectra were provided for each record. in this study, the seismic moment of ezgeleh main shock was calculated using keilis-borok method (1960) and its mean value is 1.45e+27 dyne-cm. by using brune(1971) method, source radius and stress drop of this event is calculated 12 km and 394 bar respectively.
