                            <p>This study analyzes the ground motion characteristics of the 10 August 2025 Sındırgı (Mw 6.1) earthquake using multi-station records. Time-domain (PGA, PGV, PGD) and frequency-domain (response spectra, FFT-based dominant period) analyses were performed for ten stations in E-W, N-S, and U-D components. Stations were compared by epicentral distance (5-65 km) and site class (Vs30 → ZC/ZD). Higher amplitudes were observed at near-fault stations, while station 4504 showed significant site amplification and possible directivity effects. Dominant periods correlated with Vs30 values. Observed PGA values showed good agreement with NGA-West2 GMPEs, especially for ZD sites (R² = 0.82-0.88). Results emphasize the importance of considering local site and directivity effects along with epicentral distance in engineering design.</p></trans-abstract>

Zaman ortamı (PGA, PGV, PGD) ve frekans ortamı (tepki spektrumları, FFT baskın periyot) analizleri, D-B, K-G ve Z bileşenlerinde yer alan on istasyon için gerçekleştirilmiştir. İstasyonlar, episantr uzaklığına (5-65 km) ve zemin sınıfına (Vs30 → ZC/ZD) göre karşılaştırılmıştır. Yakın fay istasyonlarında daha yüksek genlikler gözlenirken, 4504 numaralı istasyon önemli yer büyütmesi ve olası yönelim etkileri göstermiştir. Baskın periyotlar Vs30 değerleri ile ilişkili bulunmuştur. Gözlenen PGA değerleri, özellikle ZD yerleri için (R² = 0.82-0.88) NGA-West2 GMPE&#039;leri ile iyi bir uyum göstermiştir. Sonuçlar, mühendislik tasarımında episantr uzaklığının yanı sıra yerel yer ve yönelim etkilerinin de dikkate alınmasının önemini vurgulamaktadır.</p></abstract>
