Öz

In this study, velocity field and strain rates were obtained by GPS velocities solely and GPS data with constraints from seismicity.The study area is the western part of North Anatolian Fault Zone NAFZ . The algorithm developed by Haines and Holt was applied to the dataset. Geodetic data were GPS velocities 2003-2005 and seismic data were focal mechanism solutions of earthquakes with magnitude larger than 4 in a 30-year time interval. Results show that the east-west shortening of western NAFZ are related to right-lateral faulting. The minimum velocity value by the evaluation of GPS campaigns is 0.42 mm/yr and the maximum velocity is 25 mm/yr. The south branch of western NAFZ have movements towards west and south-west direction. Strain rates show the north-south extension of the western NAFZ

Bu çalışmada, GPS hızları ve jeodezik veri ile zorlanmış sismik veriler kullanılarak hız alanı ve gerinim oranları elde edilmiştir. Çalışma alanı Kuzey Anadolu Fay Zonu KAFZ batı kesimidir. Haines ve Holt tarafından geliştirilen algoritma kullanılmıştır. Jeodezik veri, GPS hızlarıdır 2003-2005 . Sismik veriler, 30 yıllık zaman aralığında büyüklüğü 4’ün üzerindeki depremlerin odak mekanizması çözümleridir. Elde edilen sonuçlardaki doğu-batı kısalması Kuzey Anadolu Fay Zonu batı kesiminin sağ yanal atımlı karakteristiğini yansıtmaktadır. GPS kampanyalarından elde edilen minimum hız 0.42mm/yıl, maksimum hız 25mm/yıl’dır. Güney koldaki hareket batı-güneybatı yönündedir. Gerinim oranları Kuzey Anadolu Fay Zonu batı kesimindeki kuzey-güney genişlemesini göstermektedir.
