Seismic wave propagation in subsurface media endures from absorption, which can be evaluated by the seismic quality factor Q (Q-factor). Absorption is frequency-dependent. Lower frequencies are absorbed less, while higher frequencies are absorbed more. Therefore, the Q Factor should be determined in the frequency domain. Q-factor is determined by the slope of the natural logarithm of the output-input signals ratio. Surface waves (Rayleigh and Love waves) are particularly important, as they are the more destructive phases of an earthquake. In this study, I focused on the Q-factor computation of the surface waves and demonstrated that the determination of the Q-factor is not affected from the dispersive properties of the surface waves. Data were obtained from surface wave signals of earthquake recorded at Eskisehir Technical University Seismic Network EstuNet. The obtained Q-factor values represent the average values of the rocks that the waves cross between the input and output stations. Finally, I compared the Q-factor map to the Peak Ground Acceleration (PGA) map using the M=4.3, 17.01.2015 Eskisehir earthquake data. These records, which show the arrival time of the earthquake from the epicenter to the stations of the seismic waves, and the peak ground acceleration values. In this study, local site effects of EstuNet accelerometric stations have been calculated by using the Standard Spectral Ratio (SSR) method. I concluded that an inverse relationship exists between the computed Q-factor and measured PGA values. Therefore, the sites where the Q factor is very low should be analyzed in more detail in ground-based earthquake risk assessments.

Received Date: 10.09.2020 Accepted Date: 08.12.2020 ABSTRACT The study area covers the northern coasts of Cyprus from the Güzelyurt Gulf to the Gazimağusa Gulf. This study was carried out in order to reveal the presence of the alien foraminifera, which are widely distributed in the Eastern Mediterranean particularly Amphistegina lobifera in the study area, and the effects of trace elements on faunal assemblages (foraminifera, ostracod and mollusc). The bottom sediment samples were taken from eighteen different points and depths, the faunal assemblages were examined, and the sediment distribution map of the studied area was made by ICP-MS analysis and geochemical evaluations. 30 genera and 48 species of foraminifera have been identified, of which 9 species belonging to 6 genera are the alien foraminifera. These are: Spiroloculina angulosa, S. antillarum, Hauerina diversa, Coscinospira hemprichii, Peneroplis pertusus, P. planatus, Amphisorus hemprichii, Sorites orbiculus and Amphistegina lobifera. Amphistegina lobifera was observed to be abnormally abundant in most of the samples. This foraminiferal assemblage of Red Sea origin constitutes a poor assemblage compared to the alien assemblages in Turkish Mediterranean coastal areas. It has been determined that the ostracod and mollusc genera and species found in the same samples belong to the typical Mediterranean and Aegean Sea community. Alien foraminifers of the northern and northeastern coastlines of Cyprus Island
