Contemporary Ottoman sources bring a major contribution to the description of the seismic activity in the eastern Mediterranean region and are extensively used by historical seismologists. Among these, the documents of the Ottoman State Archives (Istanbul), and more specifically the correspondence of the local governors with the central authorities form a valuable source for the description of the earthquake effects in territories, which were under the Ottoman rule. Especially for the more recent periods, we observe that not only major earthquakes but also small‐to‐moderate‐size events with local effects find their place in these documents. However, due to the complex and insufficiently categorized structure of the archival material, as well as the need for expertize in Ottoman language and history, except the sections covered in the works of N. Ambraseys and C. Finkel and a number of earthquake‐specific studies, these documents are not yet fully exploited in the definition of the regional seismic history.In this pilot study, we investigate the Ottoman archive material related to earthquake effects in the central North Anatolian region and search for possible supportive or new contribution to the seismic history of the study area. The period of investigation is the nineteenth century, with occasional data also found for the pre and postperiod. The study revealed supportive information for 15 earthquakes that were already known to previous compilations, and data for 19 earthquakes that we categorize as new events, demonstrating the value of this primary source and the wealth of macroseismic information that can still be extracted, revealing earthquakes so far unknown as well as enriching the descriptive information related to already known ones.

中北部安那托利亚地区的地震史：奥斯曼档案馆的新贡献

当代的奥斯曼起源对描述地中海东部地区的地震活动做出了重大贡献，并且被历史地震学家广泛使用。在这些文件中，奥斯曼国家档案馆（伊斯坦布尔）的文件，更具体地说是地方州长与中央政府的往来信件，是描述受奥斯曼帝国统治的领土上地震影响的宝贵来源。特别是在最近时期，我们观察到不仅在这些文件中，不仅发生了大地震，而且发生了局部影响的中小规模的事件。但是，由于档案材料的结构复杂且分类不充分，以及需要对奥斯曼语言和历史进行专业化处理，但N的著作所涵盖的部分除外。Ambraseys和C.Finkel以及许多针对地震的研究，这些文件尚未在区域地震史的定义中得到充分利用。在本项试验研究中，我们调查了与北安纳托利亚中部地震影响有关的奥斯曼档案材料区域并寻找对研究区域地震历史的可能的支持或新的贡献。调查的时期是19世纪，偶尔也可以找到时期前后的数据。该研究揭示了以前的汇编已经知道的有关15次地震的支持性信息，以及我们归类为新事件的19次地震的数据，证明了这种主要来源的价值以及仍然可以提取的大量地震信息，
