The crustal structure beneath the northwest of the Zagros (KermanshahRegion) from teleseismic receiver functions

In this study, we used teleseismic data which was recorded by 5 stations (dhr, ghg,kom, lin and vis) of the kermanshah seismic network from 2003 to 2007 withmb~5.5 and epicentral distances from 30° to 95°. the crustal structure beneath thesestations was determined by the modeling of the p receiver functions . the main phases,which were observed in our final p receiver functions, are moho conversions, theirmultiples in the crust, and conversions at the base of the sediments. we obtained a 2-layermodel for the crust of the kermanshah region. the crust beneath this region isapproximately 42 km thick and consists of a 9 to 18 km thick sedimentary layer overlyinga 24 to 35 km thick layer. the average shear wave velocity was estimated to be 3.69krns in the crust and reaches to 4.80 kms' under moho and those obtained from othergeophysical studies.
