Data are obtained from the International Seismological Center (ISC), where earthquake magnitudes are reported in different scales and come from a variety of sources. For establishing a common magnitude expression, namely an equivalent moment magnitude Graphic, new relations correlating the different magnitude scales with each other are derived from converting as many as possible of the magnitudes reported in the ISC bulletins. After magnitude conversions, the completeness magnitude Mc is sought by modifying the goodness‐of‐fit method of Wiemer and Wyss (2000) to become more appropriate for datasets with smaller sample size and higher Mc thresholds. The study region is divided into four smaller regions on the basis of spatial data homogeneity, while different periods of similar seismic network performance are recognized and tested to seek spatiotemporal variation of Mc. The results derived in each case are compared with those yielded by the application of both the original goodness‐of‐fit and maximum curvature methods and are found to be quite similar, although there are still cases with a difference exceeding 0.3 magnitude units. The goodness‐of‐fit method is very sensitive in the selection of the desirable percentage of fitting a power law (90% or 95%), whereas the proposed modification makes it independent of this level selection, and performing better especially for datasets that include events before 1990, when higher completeness magnitudes are evident. date: 2013-10 date_type: published publication: Bulletin of the Seismological Society of America volume: 103 number: 5 publisher: Seismological Society of America pagerange: 2739-2751 id_number: doi:10.1785/0120120174 refereed: TRUE issn: 0037-1106 official_url: http://dx.doi.org/10.1785/0120120174 access_IS-EPOS: limited software_references: Completeness_Magnitude_Estimation owner: Publisher citation: Leptokaropoulos, Konstantinos Michail and Karakostas, Vassilios G. and Papadimitriou, Eleftheria E. and Adamaki, Aggeliki K. and Tan, Onur and Inan, Sedat (2013) A Homogeneous Earthquake Catalog for Western Turkey and Magnitude of Completeness Determination.
