Isotatic compensation Western Anatolia with estimate of the effective elastic thickness

Isotatic compensation Western Anatolia with estimate of the effective elastic thickness

İzostazi, sınırlı uzay ve zaman ortamında yer değiştiren yüklere karşı kabuk ve mantonun nasıl bir tepki verdiği ile ilgilidir. Gravite ve topoğrafya verilerinin frekans içeriğini analiz ederek, bir alana ait dengeleme mekanizması tanımlanabilir. Bu çalışmada, dinamik yüklere sahip Batı Anadolu Bölgesi’nin dengeleme mekanizması, izostatik yanıt fonksiyonları ile incelenmiştir. Batı Anadolu Bölgesi’ndeki efektif elastik kalınlık kestirimi, gravite ve topografya verileri arasındaki girişim (admittance) ve uyuma (coherence) bağlı olarak yapılmıştır. Deprem odak dağılımı ve gravite ile topografya arasındaki ilişki, litosferik dayanımın en iyi iki göstergesidir. Bu amaçla, sismojenik kalınlık ve Batı Anadolu’nun termal yapısı arasında efektif elastik kalınlık ile ilişki kurulmuştur. Bu çalışmanın sonucunda Batı Anadolu’ya ait litosferik dayanımın ortalama 6 km olduğu saptanmıştır.
