On September 5, 2012, a powerful explosion occurred in Ammunition Depot No. 32 located in the Şehit Uzman Çavuş Mete Saraç Barracks of the 500th Engineering Main Depot Command in Afyonkarahisar. In this study, seismic and acoustic wave records related to the explosion were analysed in both time and frequency domains. Analysis of the seismograms determined that the explosion occurred at 18:07:53.87 (UTC) with a magnitude of ML=1.4. Among three different yield estimation methods, the secondary shock wave delay time-based analysis was found to be reliable, and the amount of explosive material was estimated to be 21 tons. In the frequency domain studies, it was determined that the P-waves were dominant at around 3 Hz and the acoustic waves at around 20 Hz. Furthermore, findings from frequency domain analyses indicated the occurrence of multiple explosions within a very short time frame. Seismological investigations related to explosions can significantly contribute to forensic processes, crisis management, and emergency planning.

5 Eylül 2012 tarihinde Afyonkarahisar’daki 500. İstihkâm Ana Depo Komutanlığı Şehit Uzman Çavuş Mete Saraç Kışlası’nda bulunan 32 nolu mühimmat deposunda kuvvetli bir patlama meydana gelmiştir. Bu çalışmada patlamaya ilişkin sismik ve akustik dalga kayıtları zaman ve frekans ortamında incelenmiştir. Sismogramların analizinde patlamanın 18:07:53.87 (UTC)’de gerçekleştiği ve büyüklüğü ML=1.4 olarak hesaplanmıştır. Üç farklı verim tahmini yönteminden ikincil şok dalgası gecikme süresi temelli analiz güvenilir bulunmuş ve infilak eden madde miktarı 21 ton olarak tespit edilmiştir. Frekans ortamı çalışmalarında P dalgalarının 3 Hz ve akustik dalgaların 20 Hz civarında baskın olduğu belirlenmiştir. Ayrıca, frekans ortamı analizlerinde çok kısa sürede birden fazla patlamanın gerçekleştiğine dair bulgulara rastlanmıştır. Patlamalara ilişkin sismolojik araştırmalar adli süreçlere, kriz yönetimine ve acil durum planlamalarına önemli katkı sunabilirler.
