Abstract: The study area is located on the eastern part of the North Anatolian Fault Zone (NAFZ) around theKoyulhisar (Sivas) region. The region is represented by a 6-8 km wide and 32 km long deformation belt.This belt is divided in 5 fault segments by Toprak (1988) as North Anatolian Master Fault, KoyulhisarFault Set, Kelkit Fault Set, Şıhlar Fault Set and Kuruçay Fault Set. In this study, a detailed fault kinematicanalysis were carried out along the Şıhkar, Çamlıyaka, Saytepe and Dumanlıca Fault Sets aroundKoyulhisar and its surroundings. The result of kinematc analysis indicates that the region is under the effect of NW-SE compression and NE-SW extension. Morphotectonic structures and microseismic activityreveals the right lateral strike slip activity of the North Anatolian Fault Zone in this region. Intenselandslide activity in the region is seen. One of the severe landslides occurred in Koyulhisar in 2000 is stillaffecting the region. GPS monitoring of this landslide reveals an average of 2.5-7.4 mm/year slip rate.
