L’Aquıla (İtalya) depreminin özellikleri ve deprem bilimi ve mühendisliği açısından önemi

Abstract

Moment büyüklüğü 6.3 olan L’Aquila depremi, İtalya’nın orta kesimindeki Abruzzi bölgesinde 6 Nisan 2009’da meydana gelmıştir. Deprem 294 kişinin yaşamını yitirmesine ve L’Aqulia kentinde ağır hasar meydana gelmesine neden olmuştur. Yazarlar, depremden hemen sonra depremin neden olduğu hasarı incelemişlerdir. Deprem normal bir faydan kaynaklanmış olup, özellikle fayın tavan bloğu üzerinde bulunan yerleşimlerde oldukça ağır hasarlara neden olmuştur. Bu çalışmada, L’aquila depreminin özellikleri ve deprem bilimi ve mühendisliğindeki önemi ile etkileri sunulmuştur. Bunun yanı sıra, yapılarda görülen ağır hasarlar ile bunların nedenleri sunulmuş ve tartışılmıştır. Ayrıca deprem tahmini yapıldığına ilişkin haberlerin doğruluğu bilimsel olarak incelenmiş ve bu öngörünün deprem tahmini için gerekli koşulları sağlamadığı görülmüştür. Gözlenen hasarlarının başlıca nedenleri, yapıların depreme karşı dirençlerinin düşük olması ve deprem yönetmeliklerinin uygulanmamış olmasıdır
