In this study, the P receiver function technique beneath the west Iran is used to map out the lateral variation of the Moho boundary. The teleseismic data (Mb ≥5.5, epicentral distance between 30˚-95˚) recorded from 2004 to 2016 at 17 permanent broadband and short-period stations of the Iranian Seismological Center (ISC, http://irsc.ut.ac.ir) of Kermanshah, Khoramabad, Hamedan and Boroujerd and one broadband station of the International Institute of Earthquake Engineering and Seismology (IIEES, http://www.iiees.ac.ir) were used. The results indicate clear Ps conversions at the Moho boundary. The Moho depths are estimated from the delay time of the Moho converted phase relative to the direct P wave beneath each network. The average Moho depth lies at ~42±2 km. Furthermore, the clear image of the Moho at depths as modeling of PRF, ranging from 37 km beneath KCHF station to maximum 55 km beneath HAGD station was presented. According to the distribution and number of stations used, this study is more comprehensive than previous studies.
