Abstract

Bu çalışmada, 10 Mayıs 1997 Qa’enat depreminin (Mw=7.2) sonlu-fay kırılma özellikleri araştırılmıştır. Hartzell ve Heaton (1983) tarafından geliştirilen bir lineer sonlu-fay ters çözüm yöntemi sonlu-fay kaynak özelliklerini elde etmek için geniş bant telesismik P ve SH cisim dalga şekillerine uygulanmıştır. 1997 Qa’enat depreminin çoklu-segment sabit rake açılı sonlu-fay modeli, kırılmanın üç pürüzün yenilmesiyle kontrol edildiğini, en büyük kaymanın 340 cm ile ortada yer alan pürüz üzerinde olduğunu, güneye doğru tek yönlü olarak ilerlediğini, 36 saniye sürdüğünü ve 1.26x1027 dyn.cm’lik bir sismik momenti serbestlediğini göstermiştir. Kuzeydeki pürüz 30x15 km2’lik bir kırılma alanı ile 220 cm maksimum kayma genliğine ve güneydeki pürüz 12x15 km2’lik bir kırılma alanı ile 220 cm maksimum kayma genliğine sahiptir. Benzer bir kayma dağılım modeli, kayma genliklerinde küçük farklılıklar ve daha sığ güney pürüz ile rake açısının 90o-180o aralığında değişimine izin verildiğinde de elde edilmiştir. Ayrıca değişken rake açılı ters çözüm, depremin baskın olarak sağ yanal kayma nedeniyle olduğunu ve arazide gözlendiği gibi güney pürüzde önemli bir ters kayma bileşenine sahip olduğunu göstermiştir. Değişken rake açılı ters çözüm için sismik moment 1.18x1027 dyn.cm olarak hesaplanmıştır.
