摘要：In this study, we aimed to obtain quality factor and absorption coefficient of crust of Erzincan city and its surrounding. In total 89 near-field earthquake data recorded by the Erzincan Station of Atatürk University Earthquake Research Center (AUERC) were used for the calculations. Maximum amplitudes of Pn waves were used in order to compute the earthquake magnitude. The linear equations systems obtained for the all events were solved using the least-squares method. Thus, a local magnitude formula as a function of amplitude was described for the Erzincan station as (ML=0.5148logA+0.0039Δ+4.2104). Amplitude normalization process was performed for a reference value ML= 4, so as to correct effect of the magnitudes. The attenuation on calculation of absorption coefficient (γ) of 0.0176 km-1 and quality factor (Q) 28.5 were obtained with the assistance of normalized amplitudes values for the region.
