Özet:

 Many earthquakes have occurred in Turkey from past to present due to the fact that it contains active fault zones within its borders. These earthquakes caused significant loss of life and property. These losses have deeply affected the people living in the country, both materially and spiritually. Finally, two major earthquakes centered in Kahramanmaraş, which occurred on 06 February 2023 with an interval of 7 hours, were added. After the earthquake that occurred at 04.17 in the section where the Eastern Anatolian Fault Zone meets the Dead Sea Fault Zone, another earthquake occurred on the Çardak Fault, another branch of the Eastern Anatolian Fault Zone, at 13:24 local time. 11 provinces were affected by the earthquakes felt in a very large area, and more than 14 million people were harmed by the earthquake. The damages that occur are loss of life and economic losses due to structural damage. In the region affected by the earthquake, many buildings collapsed completely, and some of them became unusable with heavy damage. This study, on the other hand, aims to evaluate the actual losses by using the methodology used in the loss assessment study, which can predict losses due to earthquakes. Actual losses and estimated losses in 11 provinces were compared. The modified death coefficients used in the loss of life estimates and the actual results have taken similar values. Even though the heavily damaged and destroyed numbers do not exactly match in the cities where the destruction is great, it has been observed that the loss estimation stages are applied in general, giving similar results. The results of the study were examined and the results were analyzed with their justifications.

 Türkiyede, aktif fay zonlarını sınırları içerisinde bulundurması sebebiyle geçmişten günümüze kadar, birçok deprem meydana gelmiştir. Bu depremler önemli can ve mal kayıplarına neden olmuştur. Bu kayıplar maddi ve manevi olarak ülkede yaşayan insanları derinden etkilemiştir. Bunlara son olarak 06 Şubat 2023 tarihinde yaklaşık 9 saat arayla meydana gelen Kahramanmaraş merkezli iki büyük deprem eklenmiştir. Doğu Anadolu Fay Zonunun Ölü Deniz Fay Zonu ile birleştiği bölümde 04.17de meydana gelen deprem sonrasında, yerel saatle 13.24te Doğu Anadolu Fay Zonunun başka bir kolu olan Çardak Fayında diğer deprem meydana gelmiştir. Çok büyük bir alanda hissedilen depremlerden 11 il etkilenmiş, 14 milyonun üzerinde insan depremden zarar görmüştür. Meydana gelen zararlar yapısal hasar kaynaklı can kayıpları ve ekonomik kayıplardır. Depremden etkilenen bölgede birçok yapı tamamen göçmüş, bir bölümü ise ağır hasarlı bir şekilde kullanılamaz hale gelmiştir. Bu çalışma ise deprem kaynaklı kayıpları önceden tahmin edebilen kayıp değerlendirilmesi metodolojisi kullanarak gerçekte meydana gelmiş kayıpların değerlendirilmesi amaçlamıştır. 11 ildeki gerçek kayıplar ile tahmin edilen kayıplar karşılaştırılmıştır. Can kaybı tahminlerinde kullanılan modifiye edilmiş can kaybı katsayıları ile gerçek sonuçlar benzer değerler almıştır. Yıkımın büyük olduğu şehirlerde ağır hasarlı ve yıkık bina sayıları tam olarak örtüşmese dahi, genel olarak kayıp tahmin aşamaları uygulandığında benzer sonuçlar verdiği görülmüştür. Çalışma sonuçları incelenmiş, sonuçlar gerekçeleri ile irdelenmiştir.
