Abstract

The seismicity of eastern Transbaikalia has not been studied extensively. According to the current estimate, the seismic activity in this area is defined as moderate and low. At the same time, there is some historical evidence to show that major seismic occurrences have repeatedly taken place in various areas of Transbaikalia. The evidence is fragmentary and for this reason has not been taken account of when developing parametric catalogs and for seismic hazard assessment in eastern Siberia. The present paper considers some new data that throw light on the macroseismic effects of some large historical earthquakes in eastern Transbaikalia and permit estimation of their basic parameters. Additional material was discovered when inspecting the regional periodicals that were published in the late 19th and early 20th centuries. This study suggests higher seismic activity for eastern Transbaikalia than thought previously.
