The receiver function analysis method was implemented to determine the crustal structure around Ankara, Central Anatolia. Teleseismic earthquake records are used in this method which is based on the conversion of incident P waves into S waves reaching an interface in the crust or upper mantle and arrival of the converted wave to the station just after the direct P waves. A temporary seismic network, Ankara Earthquake Monitoring Network, consisting of six broad-band seismograph stations has been deployed to monitor the seismicity in Ankara and vicinity in the period 2007-2010. In this study, the crustal thicknesses beneath AnkNET stations were calculated. The stations between latitudes 39° - 41° N and longitudes 32° - 34° E were located about 100 km apart from each other through a circle with radius about 100 km, including one in Ankara. Hypocentral parameters of 43 earthquakes which are equal or greater than an instrumental magnitude of 6.5 occurred at a distance between 30°-100° far from the central coordinates of AnkNET (40°N, 33°E) were retrieved from IRIS earthquake catalogue. According to the results of the study, the crustal thickness of the region ranges from 32.8 km to 39.05 km with an average of about 35.66 km.
