The thick solid line shows the achieved 1D P-wave velocity model, which was used in this study as the starting velocity model for tomography inversion. The dashed lines denote all input models to perform stability tests and thin solid lines show corresponding output models. Dotted line shows the Bayramnejad (2007) model, used as one of our initial testing models for VELEST inversion. The Moho depth at 45 km is inferred from Taghizadeh-Farahmand et al. (2010) who documented depth variation from 38 km in west to 53 km in the eastern part of study area. Arrow shows the Conrad discontinuity between the upper and lower crust
