摘要: Anderson ve Hough (1984) tarafindan ilk kez kullanilmaya baslanan spektral sonum parametresi, κ (kappa), bircok uygulamada gittikce artarak kullanilmaktadir bir istasyonda kaydedilmis kuvvetli yer hareketinin alanda yuksek frekanstaki egimini ifade eder. Gectigimiz son yillarda, kappa tahmini deprem tehlike analizi sonuclarina etkisi uzerine yaklasim gelistirilmistir. Kappa’nin zemin kosullarina bagli olarak, frekans araligindaki hareketinde degerlerinde 3 hatta zemine olarak 6 kat artis gozlemlenmistir. Bu parametrenin onemi sebebiyle Van Bolgesi icin tespit edilmeye calisilmistir. calismada, tahminleri Afet Acil Durum Yonetimi Baskanligi Kuvvetli Yer Hareketi gozlem agina ait (AFAD) bolgesindeki istasyonlarindan alinan ivme-olcer kayitlari kullanilmistir.
