Abstract:
The tectonic structure of our country is the result of collision of Arabian, African and Eurasian plates. Deformation towards to the west of the Karlıova region, which is the conjunction of North Anatolian Fault Zone with East Anatolian Fault Zone, is caused by the strike-slip faulting along North Anatolian Fault Zone and East Anatolian Fault Zone and the deformation from this intersection area to the east is caused by the thrust faults exist in the region. In Eastern Turkey, many scientific studies have been conducted with applying geodetic methods. In this study, six epochs of data from 19 of CORS-TR stations were used and data was chosen by considering seasonal effects. GAMIT/GLOBK academic software was used to process the data and obtain velocity field of the study area. The obtained velocities of stations were combined with the velocity fields of Reilinger et al., (2006) and Aktuğ et al., (2013). The transformation process is performed by using 13 IGS stations which are mutual in the studies. Obtained velocity values vary between 3.77 mm/yr ±0.52 mm/yr and 24.94 mm/yr ±5.34 mm/yr. The results obtained show consistency with the recent tectonic structure of the region. The results of prior studies in the study area is considered and taken into account within the processing of data which made it possible to consider a long term data set. Long term data set allowed obtaining the velocity field of the area more accurately.
