Abstract. Researches aimed at enriching the number of available documentary sources on earthquakes have an important role in seismology. To this end, this paper documents the history of prominent earthquakes associated with the NW-SE trending Sultandag-Aksehir Fault and Aksehir-Afyon graben system in Western-Central Anatolia since the historical times through 1766. This work also combines the earthquake data for both historical and instrumental periods, previously listed in various catalogues and resources, for the studied area.

Documents from the Ottoman archives and libraries as well as the Ottoman and Turkish newspapers were scrutinized, and eight previously unreported earthquakes in the latter half of the nineteenth century and four new earthquakes in the period 1900–1931 were revealed. For the period from 1766 to 1931, the total number of known earthquakes for the area under investigation increased from eighteen to thirty thanks to the document search. Furthermore, the existing information on eleven previously reported earthquakes is updated for the period from 1862 to 1946. Earthquakes from 1946 to 1964 are compiled from the catalogues for data completeness.
