Timing of Late Holocene earthquakes on the eastern Düzce Fault and implications for slip transfer between the southern and northern strands of the North Anatolian Fault System, Bolu,Turkey
Öz: Düzce Fayı'nın doğusundaki fay kazısı çalışmaları, 1999 Düzce depreminden önce de yüzey kırığı oluştuğunu ortaya koymuştur. Önceki depremlerde meydana gelen yüzey kırıklarının yeri aynı olup, yerdeğiştirme miktarı, tipi ve büyüklüğü 1999 depremindekine benzerdir. 1999 depreminden önce bu fay üzerinde meydana gelen en son deprem 300 yıl önce olmuştur. Bu fay üzerinde son 2100 yıl içerisinde 1999 Düzce depremi de dahil olmak üzere en az 4 veya muhtemelen 5 deprem olmuştur. Bu depremlerin tekrarlanma aralığı 300 ile 800 yıl arasında değişmektedir. Düzce Fayı da dahil, Kuzey Anadolu Fay Sistemi'nin kuzey ve güney kolları üzerindeki kümülatif kaymanın hesaplanması, fay üzerinde biriken elastik deformasyonun tamamı değilse bile önemli bir kısmının bu lokasyonda açığa çıktığını göstermektedir. Paleosismolojik veriler ve yapısal haritalama çalışmaları esas alındığında, Bolu yakınlarında Elmalık ve Bakacak ikincil aktif faylarının Kuzey Anadolu Fay Sistemi'nin kuzey ve güney kolları arasındaki yapısal ve kinematik bağlantıyı kurdukları görülmektedir. Düzce Fayı ve Kuzey Anadolu Fay Sistemi'nin güney kolu arasındaki bu faylar Bolu Havzasının batı kenarı boyunca uzanmaktadır. Bakacak Fayı'ndaki 1999 yüzey kırığı ve Holosen'de yerdeğiştirme olduğunu gösteren paleosismik veriler, Bakacak ve Elmalık fayları ile Kuzey Anadolu Fay Sistemi'nin kolları arasında kaymanın aktarıldığını ortaya koymaktadır.

Öz: Results of trenching across the eastern Düzce Fault document that surface rupture has occurred repeatedly on the fault prior to the 1999 Düzce earthquake, and that offset during previous earthquakes occurred at the same location and with similar amounts and type of slip as that of the 1999 earthquake. The most recent pre-1999 earthquake on the fault occurred about 300 years ago. At least four and possibly five earthquakes (including 1999) have occurred in the past 2100 years. The earthquake recurrence interval ranges from 300 to 800 years. Estimates of cumulative slip on the northern and southern branches of the North Anatolian Fault System (NAFS) (including the Düzce Fault) show that most, if not all, accumulated elastic strain on the fault has been coseismically released at this location. Based on our mapping and palaeoseismic data, it appears likely that the southern and northern strands of the NAFS are structurally and kinematically linked in the vicinity of Bolu by active secondary faults, including the Elmalık and Bakacak faults. These faults extend along the western boundary of the Bolu Basin, between the Düzce Fault and the southern strand of the NAFS. The documented 1999 rupture on the Bakacak Fault and palaeoseismic evidence of previous Holocene displacement strongly suggest that the Bakacak and Elmalık faults transfer slip between the strands of the NAFS.
