Description:
Here we present first-order results detailing the Anatolian crustal from receiver function analysis of data from approximately 300 stations within Turkey. Seismic data from the Kandilli Observatory array (KOERI; KO), the National Seismic Network of Turkey (AFAD-DAD; TU) and available IRIS data from the Northern Anatolian Fault experiment (YL) for the period between 2005 and 2010 is analysed. We calculate receiver functions in the frequency domain using water-level deconvolution. The results are analysed using a combination of H–K stacking and depth stacking to determine robust Moho conversion depths and V P / V s ratios across Anatolia. We detect a deep Moho in eastern Anatolia of up to ~55 km, a generally normal Moho in Central Anatolia of ~37–47 km and a thinned Moho in western Anatolia and Cyprus of ~30 km. The V P / V s ratio across the Anatolian Plate is generally slightly elevated; regions of extremely high V P / V s ratio (〉1.85) can be associated with recent volcanism in eastern and central Anatolia. High V P / V s ratio measurements (〉1.85) in western Anatolia may be indicative of partial melt in the lower crust associated with regional extension.
