Monitoring of Deformations Along Burdur Fethiye Fault Zone with GPS

Abstract

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 20th 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 GAMI...
