The Marmara region, located between the Eurasian and Anatolian plates, experiences intense seismic activity, necessitating ongoing hazard assessment. This study integrates spectral seismic attributes—such as dominant frequency ranges, spectral decay, and corner frequencies—to investigate how tectonic stress is distributed and released. Seismic data from the Kandilli Observatory and Earthquake Research Institute (KOERI) and the Incorporated Research Institutions for Seismology (IRIS) were processed via Fast Fourier Transform (FFT) to derive seven parameters (Peak Frequency, Spectral Decay, Spectral Ratio, Low Band Power, Medium Band Power, High Band Power, and Corner Frequency). These parameters capture various aspects of energy dissipation, attenuation, and fault mechanics essential for seismic analysis. We then employed Ordinary Kriging to map their spatial variations. The findings indicate significant stress in central and eastern Marmara, while the northwestern region near the North Anatolian Fault (NAF) exhibits marked energy release. By correlating these seismic attributes with potential stress states, this work contributes to a refined assessment of seismic hazard in the Marmara region and offers valuable insights for enhancing risk management strategies.
