Abstract—

Materials on earthquakes in Samarkand and Ferhana regions (Republic of Uzbekistan) in 1868–1892 are presented based on original sources of information not used before. The epicenter location and magnitude for the earthquakes April 7, 1869, and March 2, 1892, are evaluated for the first time; for the other two earthquakes (April 3, 1868, and September 18, 1892), the uncertainty of previously published solutions is significantly reduced. Reduction of uncertainties of prior solutions is achieved owing to the formalized method of epicentral and magnitude assessment, which works successfully with sparse datasets. One of the restrictions on the entire set of solutions is association of the epicenter with certain active tectonic structures. This criterion is used only for selecting the preferable solution from the entire set of solutions obtained solely from macroseismic data. The complete set of solutions is retained and can be used to analyze the accuracy and objectivity of the preferable solution.

摘要-

根据以前未使用过的原始信息，介绍了1868–1892年撒马尔罕和费哈纳地区（乌兹别克斯坦共和国）地震的材料。首次评估了1869年4月7日和1892年3月2日地震的震中位置和震级；对于其他两次地震（1868年4月3日和1892年9月18日），以前发布的解决方案的不确定性大大降低了。归因于震中和震级评估的形式化方法，减少了先前解决方案的不确定性，该方法可成功用于稀疏数据集。整套解决方案的限制之一是震中与某些活跃的构造结构的联系。该标准仅用于从仅从宏观地震数据获得的整套解决方案中选择最佳解决方案。完整的解决方案集将保留下来，可用于分析首选解决方案的准确性和客观性。
