Two major earthquakes with magnitudes of Mw = 7.7 and Mw = 7.6 occurred on 6 February 2023 Kahramanmaraş, Türkiye, which is located on active earthquake zones. Unfortunately, the earthquakes caused more than 50,000 casualties and significant structural damage in 11 different provinces. This study evaluated the Kahramanmaras earthquakes from an energy perspective. First of all, the acceleration records from seismic stations in the region most affected by the earthquakes were analyzed and the input energy spectra of each station was obtained. Consequently, the input energy density maps of the studied region for different period values are presented and evaluated.

6 Şubat 2023 Pazarcık ve Elbistan (Kahramanmaraş) Depremlerinin Giren Enerji Açısından İncelenmesi

Öz

Aktif deprem kuşakları üzerine yer alan Türkiye’de, 6 Şubat 2023 tarihinde Mw =7.7 ve Mw =7.6 büyüklüğünde iki büyük deprem meydana gelmiştir. Depremler ne yazık ki 50.000'den fazla can kaybına neden olmuş ve 11 farklı ilde önemli yapısal hasarlara yol açmıştır. Bu çalışma kapsamında Kahramanmaraş depremleri enerji esaslı değerlendirilmiştir. Öncelikle depremlerin en çok etkilediği bölgede bulunan sismik istasyonlarda kaydedilen ivme kayıtları ele alınmış ve her bir istasyona ait giren enerji spektrumları elde edilmiştir. Sonuç olarak farklı periyot değerleri için çalışılan bölgeye ait giren enerji yoğunluk haritaları sunulmuş ve değerlendirilmiştir.
