The morphotectonic features of the TGFZ and the distribution of the epicenters of earthquakes over magnitude show that this fault zone remains active today. In this study, the deformation of the TGFZ is determined with high sensitivity using geodetic measurements. To obtain accurate information about the deformation of the TGFZ, 24 GNSS sites and two continuously operating reference stations were constructed in the southern part of the TGFZ. Between 2018 and 2020, Global Navigation Satellite Systems (GNSS) measurements were made on this network. The data of the Turkish National Fundamental GPS Network (TNFGN) and the continuously operating reference stations-Turkey (CORS-TR) sites around the study area were also included in the study, and GNSS measurements were evaluated with the GAMIT/GLOBK software, and velocity fields of the region were determined. | Turkish Journal of Earth Sciences Turkish J Earth Sci 2022 31 20-33 http earth TÜBİTAK Research Article doi yer-2108-10 Determination of recent tectonic deformations along the Tuz Gölü Fault Zone in Central Anatolia Turkey with GNSS observations 1 2 3 4 5 1 Cemil GEZGİN Semih EKERCİN İbrahim TİRYAKİOĞLU Bahadır AKTUĞ Hediye ERDOĞAN 1 6 1 7 Esra GÜRBÜZ Osman ORHAN Süleyman Sefa BİLGİLİOĞLU Ahmet Tarık TORUN 1 1 8 9 Halil İbrahim GÜNDÜZ Osman OKTAR Cezmi TÜRKMEN Efdal KAYA 1 Department of Geomatics Aksaray University Aksaray Turkey 2 Department of Geomatics Engineering Necmettin Erbakan University Konya Turkey 3 Department of Geomatics Engineering Afyon Kocatepe University Afyonkarahisar Turkey 4 Earthquake Implementation and Research Center of Afyon Kocatepe University Afyonkarahisar Turkey 5 Department of Geophysical Engineering Ankara University Gölbaşı Ankara Turkey 6 Department of Geomatics Engineering Mersin University Mersin Turkey 7 Department of Geography Ağrı İbrahim Çeçen University Ağrı Turkey 8 Aksaray Provincial Directorate of Disaster and Emergency Aksaray Turkey 9 İskenderun Vocational School İskenderun Technical University Hatay Turkey Received Accepted Published Online Final Version Abstract The Tuz Gölü Fault Zone TGFZ is one of the most important active tectonic structures of Central Anatolia. The morphotectonic features of the TGFZ and the distribution of the epicenters of earthquakes over magnitude show that this fault zone remains active today.
