Abstract :In this study, the seismicity in the Sivas Basin, central eastern Turkey from 1903 to 2018 is investigated by the Gutenberg and Richter relationship insert ignore into journalissuearticles values(1944); and the maximum likelihood method insert ignore into journalissuearticles values(Aki, 1965); to explore the b-value. The b-value is regarded as one of the important parameters representing the nature of the occurrence of earthquakes. Particularly, the b-value characterizes the state of stress in the crust. The Sivas Basin exhibits the low b-value insert ignore into journalissuearticles values(0.52 and 0.9);, moderate/high heat flow values insert ignore into journalissuearticles values(70-80 mWm -2 );, large negative anomalies owing to sedimentary basin and low seismicity and the epicenter distributions of earthquakes are located at the upper crust and along the Deliler-Tecer and Yukari Kizilirmak Fault Zones in the study region.
