Abstract
Research and analyses of archive data conducted during the recent years have shown that tectonic and technogenic earthquakes have been occurring in the area of Semipalatinsk Test Site (STS) and its adjacent territories, which according to the maps of general seismic zoning of the Republic of Kazakhstan (2003) is considered aseismic. In order to assess the seismicity of the STS area, world seismological bulletins, data on historical seismicity from literature references were analyzed; parameters of earthquakes were clarified based on collected historical analog records, starting from 1925. It was shown that in this researched area during the period prior to 1994, long before the start of nuclear tests, rather strong local earthquakes were observed at STS. The obtained data were compared with the STS contemporary seismic regime.
