Burdur Fethiye fay zonu Türkiye’nin güneybatısında tektonik olarak oldukça aktif bir bölgede yer almaktadır. Tarihi kayıtlara göre bölge birçok defa depremlerle yıkıma uğramıştır. Bölgedeki tektonik hareketleri belirlemek amacıyla bölgenin karakteristiğini yansıtan 10 nokta tesis edilerek GPS ölçümleri yapılmıştır. İlk periyot ölçüler Ağustos 2003 de ikinci periyot ölçüler de Mart 2004’de gerçekleştirilmiştir. 3. periyot ölçülerde ağa 6 yeni nokta daha eklenmiştir. 4. periyot ölçümler ise Ağustos 2005’te gerçekleştirilmiştir. GPS ölçüleri GAMIT GLOBK yazılım takımı ile değerlendirilmiştir. Bu makalede GPS ölçülerinden elde edilen sonuçlar irdelenecektir.Anahtar Kelimeler: Burdur Fethiye Fay Zonu, GPS, GAMIT GLOBK.Afyon, Burdur and Fethiye region, southwest of Turkey is located on a tectonically active area. According to historical recordings, the region was destructed by earthquakes many times. In Afyon region more than 35 earthquakes occurred, whose magnitudes are more than 4, from the beginning of the 20th century. Seven earthquakes recorded which magnitudes are between 5.0 and 7.5 over the last 90 years in the region between Burdur and Fethiye (October 3, 1914 Burdur: M 7.0, August 7, 1925 Dinar: M 6.0, May 12, 1971 Burdur: M 6.2, April 25, 1957 Fethiye: M 7.1, October 1, 1995 Dinar: M 6.1, December 15, 2000 Akşehir: M 5.9, February 3, 2002 Çay: M 6.0 earthquakes. To determine tectonic characteristics of the region, a network having ten sites is established. First and second campaigns were carried out with in August 2003 and March 2004. The duration of measurement in each day was about 12 hours. After first two periods, our network is extended with six new points. Then the third campaign was performed with 16 sites at two stages in 6 days. Fourth campaign is carried out in August 2005. The duration of measurement in each day was about 8 hours. The GPS measurements for four campaigns are processed by using GAMIT/GLOBK software package. This paper examines the results from the four GPS campaigns.Keywords: Burdur Fethiye fault zone, GPS, GAMIT GLOBK
