This paper aims to study the Gokceada Island earthquake from an engineering seismological point of view. On May 24, 2014, a large earthquake of magnitude 6.5 occurred in the Northwest of Turkey. The highest recorded peak ground acceleration is at Gokceada Island station. The evaluation of site amplification effects has been carried out, using the data from the main shock and aftershocks of the earthquake. For each site, the standard spectral ratio (SSR) and horizontal to vertical spectral ratio (H/V) methods were calculated for 29 strong motion stations. The results show a clear influence of the site soil conditions on the amplification of ground motion. Furthermore, the peak ground acceleration (PGA) study was performed using attenuation relationships at 53 location sites to find out how they were affected by the ground motion. The highest PGA value was found near the epicenter, and it's attenuated with distance. We used some ground motion prediction equations to compare observed PGA values at stations with them. The measured values were significantly higher than the prediction models.
