dc.description.abstract Isparta Angle is located on southwestern Turkey and has a complex structure which is a consequence of collision between African and Anatolian plates. In order to further understand this complexity, we deployed a temporary network consisting of nineteen broad band instruments in addition to KOERI’s permanent seismic stations in the region. Crustal velocity and Moho depth variation were figured out along north – south and east – west profiles formed by fourteen temporary and permanent stations. We implemented two different receiver function methods to the recorded events. Firstly, we applied joint inversion of receiver functions and surface wave group velocities in order to model lithospheric velocity structure of the region. Receiver functions are sensitive to shear wave velocity contrast and vertical travel times, however surface wave dispersion curves are sensitive to shear wave velocity averages. Combining these different properties of shear waves may bridge resolution gaps associated with each individual data set. Secondly, Moho depth was calculated by applying H-K stacking algorithm. We found that the shear velocities for crustal and upper mantle thicknesses vary between 1.95-4.05 and 4.09-4.14 km/s, respectively, and in addition to this, Moho depth is varying between 30.5 and 40.7 km. beneath stations on the east – west profile. On the other hand, the shear velocities for crustal and upper mantle thicknesses vary between 1.41-4.05 and 3.97-4.23 km/s respectively, and the calculated Moho depth is between 35.5 and 47.0 km. beneath stations located on the north – south profile. Compared to the other geophysical studies done in the same region, this is the first study to understand unusual aspect of Isparta Angle.
