Abstract
The paper is devoted to mistakes and omissions in earthquake catalogs for East Siberia during the historical observation period. The earthquakes of 8 March 1866 and 18 May 1904 are used as examples of misinterpretations or underuse of historical evidence. The main parameters of these events have been redetermined from primary data. The paper also analyzes the "forgotten" earthquake of 1 August 1910 and the previously unknown event of 6 August 1910, which are missing from the regional parametric catalogs. It is concluded that the existing macroseismic and parametric earthquake catalogs of the study area need a thorough revision, correction, and supplementation.
