approach of using ambient noise data in additional of classical tomographic methods using seismic waves data generated by seismic sources such as earthquake would be a great help us to enhance knowledge of velocity structure crust. In this study, we determined the optimal Green's Functions using cross-correlation of a long time ambient seismic noise recorded by seismic stations. We used the continuous vertical component data which recorded by 13 broadband and 3 short-period seismometers operated by IRSC. The data were recorded for 23 months from January 2015 to November 2016. After retrieving EGF by different stacking methods, Rayleigh wave group and phase velocity were calculating. To calculate group velocity and phase velocity, we used the phase match filtering and Image transformation methods, respectively.
