Estimation of Coda‐Wave Attenuation in the Central and Eastern Alborz, Iran

The quality factor of coda ( Q c) waves has been estimated by using single backscattering and single isotropic scattering models. The earthquakes used were recorded by three permanent and one temporary network located in the central and eastern Alborz, Iran. The database was composed of 746 local earthquakes with local magnitude from 1.1 to 5.7. The estimated Q c has been found to be similar for lapse times greater than twice the S ‐wave travel time (2 t S ) for both methods. The estimated Q c for central frequencies
