Utilizing the aftershocks of the 21th, Aban, 1396 Ezgeleh-Sarpolzahab earthquake at 21:48 of local time (12th, November 2017 at 18:18 of global time), the single-back scattering method for coda waves are employed. In order to achieve this, 170 accelerograms of local earthquakes having magnitudes between 3.8 and 6 Mw recorded by the accelerogram network of the “Road, Housing and Urban Development Research Center” have been used. In addition, the equation of has been calculated for frequency bands of 1.5,3,6,12 and 24 Hz. Afterward, using recorded data of seismology by the network of Daryan, Azad and Zhave dams, the has been calculated for the region using the method of single-back scattering. For this, we have used 288 records of earthquakes with magnitudes higher than 2 at 5 high-frequency bands and different time windows, in which the calculated of the region at 30 sec time window is . The obtained results for the region demonstrate the quality factor to be lower than 200 which means the region is one of the active tectonic regions. The low values for shows a shattered and broken state of the crust of the region, which is important for us.
