Özet

The Burdur Fethiye fault zone in southwestern Turkey is located in a tectonically active area. According to historical recordings, the region has been destroyed by earthquakes many times. In this region alone, more than 90 earthquakes with magnitudes of more than 5 have occurred since the beginning of the 20(th) century. Seven of them were recorded with magnitudes between 5.0 and 7.5 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 Aksehir: M 5.9, February 3, 2002 Cay: M 6.0). To determine tectonic characteristics of the region, a network of ten sites was established and GPS measurements were made on this network. After the first year, the network was extended with six new points and additional GPS measurements were made with the financial support of TUBITAK ( Scientific and Technical Research Council of Turkey). GPS data were processed using the GAMIT/GLOBK software package. After three years, GPS measurements were processed and tectonic movements of Burdur Fethiye fault zone were observed. Velocity values of tectonic movements, fault plane solutions and the geological structure of the zone show that the zone is active.
