Herein, a combined analysis of Global Navigation Satellite System-derived strain rate maps, in accordance with recent seismicity, was presented to reveal that the N-S extension is accommodated primarily by strike-slip faulting of the İzmir-Balıkesir Transfer Zone (İBTZ), where a counter clockwise rotation (~25–100°/Myr) along the vertical axis is dominant. The results indicated that strike-slip segments within the İBTZ show variable transport sense and amount of slip along them, and they connect by hard linkage relay ramps with the dip to oblique slip normal faults. According to the strain map, the Karaburun Peninsula has the largest strain rates, at 137 nano strain (nstrain)/yr extension (NE-SW) and 126 nstrain/yr (NW-SE) compression. | Turkish Journal of Earth Sciences Turkish J Earth Sci 2021 30 143-160 http earth TÜBİTAK Research Article doi yer-2005-26 Present day strike-slip deformation within the southern part of the İzmir-Balıkesir Transfer Zone based on GNSS data and implications for seismic hazard assessment in western Anatolia Eda Esma EYUBAGİL1 Halil İbrahim SOLAK2 Umre Selin KAVAK1 İbrahim TİRYAKİOĞLU1 7 Hasan SÖZBİLİR3 4 Bahadır AKTUĞ5 Çağlar ÖZKAYMAK6 7 1 Department of Geomatics Engineering Engineering Faculty Afyon Kocatepe University Afyonkarahisar Turkey 2 Distance Education Vocational School Afyon Kocatepe University Afyonkarahisar Turkey 3 Department of Geological Engineering Engineering Faculty Dokuz Eylül University İzmir Turkey 4 Earthquake Research and Application Center of Dokuz Eylül University İzmir Turkey 5 Department of Geophysical Engineering Engineering Faculty Ankara University Ankara Turkey 6 Department of Geological Engineering Engineering Faculty Afyon Kocatepe University Afyonkarahisar Turkey 7 Earthquake Implementation and Research Center of Afyon Kocatepe University Afyonkarahisar Turkey Received Accepted Published Online Final Version Abstract Herein a combined analysis of Global Navigation Satellite System-derived strain rate maps in accordance with recent seismicity was presented to reveal that the N-S extension is accommodated primarily by strike-slip faulting of the İzmir-Balıkesir Transfer Zone İBTZ where a counter clockwise rotation 25 100 Myr along the vertical axis is dominant.
