Özet

The aim of this study is to investigate the seismicity of Central Anatolia, within the area restricted to coordinates 30-35A degrees longitude and 38-41A degrees latitude, by determining the "a" and "b" parameters in a Gutenberg-Richter magnitude-frequency relationship using data from earthquakes of moment magnitude (Mw) a parts per thousand yenaEuro parts per thousand 4.0 that occurred between 1900 and 2010. Based on these parameters and a Poisson model, we aim to predict the probability of other earthquakes of different magnitudes and return periods (recurrence intervals). To achieve this, the study area is divided into six seismogenic zones, using spatial distributions of earthquakes greater than Mw a parts per thousand yenaEuro parts per thousand 4.0 with active faults. For each seismogenic zone, the a and b parameters in the Gutenberg-Richter magnitude-frequency relationship were calculated by the least squares method. The probability of occurrence and return periods of various magnitude earthquakes were calculated from these statistics using the Poisson method.
