This study will supply an overview of crust and upper mantle structure beneath the Lake Van region based on the Receiver Function analyses of P- and S- waves using the teleseismic data set taken from the European Integrated Data Archive. All inversion results will depict the present day tectonics of the Lake Van region. Also, spatial variations of the b-values are calculated by using data covers all earthquakes occurred between 1900-2017. The b-values will inform us about the compatibility between the seismic regime and seismic velocity for the depth from near surface to 30 km.
