Abstract

Kuzeybatı Ege bölgesinin en karmaşık tektonik unsurlarını barındıran Biga Yarımadası oldukça yoğun bir dep-remsellik gösterir. Bu yarımada ve yakın çevresi için farklı dönemlerde meydana gelen orta ve büyük depremlerin deprem tehlikesi analizi, çalışmanın temelini oluşturmaktadır. Temel deprem parametreleri olarak da bilinen a ve b-değerleri bu çalışmanın veri tabanı olan aletsel dönem deprem kataloğundaki M>2 için belirlenmiş ve değerlendi-rilmiştir. Bu çalışmada, ÇOMÜ) ve KRDAE tarafından işletilen deprem istasyonları ve buna bağlı yüksek kaliteli faz okumaları sonucuna dayalı ortak bir deprem kataloğu kullanılmıştır. Ayvacık başta olmak üzere ve yakın çevresinde 6 Şubat 2017’de meydana gelen Mw=5.4 büyüklüğündeki deprem ile başlayan ve süreklilik gösteren deprem sonrası aktivitenin Tuzla deformasyon zonu çevresinde yaklaşık 25x10 km’lik bir alanda kümelendiği gözlenmiştir. Bu deprem öncesi ve sonrası yerel tektonik yapılar ve gerilme durumları ile ilişkilendirilebilecek başta b-değeri olmak üzere olasılıksal parametreler de değerlendirilmiştir. Kısa ve uzun dönemde bu parametrelerin ana deprem öncesi ve sonrası azalım ve artış eğilimleri yerel ve bölgesel hâkim gerilmelerin yanında üst kabuktaki heterojenite ve jeotermal kaynaklar da göz önünde bulundurularak sismisite ve sismotektonik yapıya katkısı ve ilişkisi uzaysal ve zamansal olarak incelenmiştir. Saroz-Ayvacık-Edremit doğrultusunda alansal olarak deprem verisi yoğunluğu dikkate alındığında b-değerlerinin gerilmelerle ters orantılı olarak deprem öncesi artışı ve akabin-de de bu davranış azalımı 2014 ve 2017 depremleri ile kendisini göstermiştir.

Abstract

The Biga Peninsula, which has the most complex tectonic segments of the northwestern Aegean region, shows a remarkable dense seismicity. The earthquake hazard analysis of medium and large earthquakes occurred at differ-ent periods for the peninsula and its vicinity is the basis of this study. The basic earthquake parameters those are generally known as a and b-values, were determined, and evaluated for the earthquakes M> 2 during the instrumental period earthquake catalog, which is the database of this study. A homogenous earthquake catalog combined of two institutions COMU and KOERI data, which are quite dense and have high solution quality, play a remarkable role in this study. It was observed that the dense seismic activity after the earthquake that initiated in the event of Mw = 5.4 on February 6, 2017, especially in Ayvacik and its close vicinity, and which has been continuing, was clustered around Tuzla deformation zone in an area of approximately 25x10 km. Probabilistic parameters including b-value which can be related with local tectonic structures and stress states before and after this earthquake were also evaluated. In the short and long term, the decreasing and increasing tendencies of these parameters before and after the main shock were examined spatially and temporally in addition to local and regional dominant stress-es, heterogeneity in the upper crust and the contribution of the geothermal resources to the seismicity and seism tectonic structure. Considering the spatial density of earthquakes towards to Saroz-Ayvacık-Edremit, the pre-earthquake b-values increased inversely with the stresses, and then this decline in behavior was distinguished in the 2014 and 2017 earthquake sequences
