Özet (Çeviri)

DETERMINATION OF THE CRUSTAL AND UPPER MANTLE STRUCTURE BENEATH THE İSPARTA SEISMOGRAPH STATION Ü. Yalçm KALYONCUO?LU Keywords : Crustal structure, Receiver function, İsparta Angle, Synthetic seismogram Abstract: The crustal structure beneath the İsparta seismograph station is derived using receiver function method. The ratio of the vertical to the radial component is called the receiver function. The receiver function is used to obtain the crustal transfer function based on thickness variation, crustal velocities, densities and the angle of emergence at the lower crust and upper mantle interface. 26 well-defined earthquakes recorded at the broad-band Isp station during the period of from 1996 to 2001 were selected for analysis based on the following criteria: focal depths with a range between 35 and 700 km, body-wave magnitudes greater than 5.5, epicentral distances with a range from 30° to 81°, and azimuthal coverage from 0° to 360°. Receiver function analysis were based on the comparison of the observed receiver function with computed receiver function from the theoretical P-wave and its S conversion motion obtained using Thomson-Haskell matrix formulation and grid search method for horizontally layered crustal models. The selection of the most suitable model was based on the identification of the theoretical model which exhibits the highest cross-correlation coefficient, lowest standard deviation and variance between observed and computed receiver function seismograms. The derived crustal model is not unique due to the theoretical assumptions (horizontal layering, constant densities and velocity in each layer), quality of the data and complexities of crustal structure. The receiver function analysis can detect a thin layer near the surface of about 2 km thick and S velocity contrast of about 60% with that of the underlying layer. The crustal models suggest that crust consist of three distinct layers. The surface layer has a S wave velocity of about 2 km/s and is about 2 km thick. The second layer has a S wave velocity of about 3.35 km/s and is about 15 km thick. The third layer shows S wave velocity of about 3.8 km/s and is 14 km thick. The Mohorovicic discontinuity beneath the İsparta indicates P wave velocity 8.0±0.2 km/s, S wave velocity 4.5±0. 1 km/s and upper mantle depth is 3 1±1 km. m
