General Seismic Zoning Map of the USSR(GSZ-78),included in the Building Code,in spite of relative improvement in comparison with previous ones(1937,1957,1968),is characterized by significant reduction of seismic hazard.In some regions strong earthquakes exceeding the predicted intensity occurred almost every year.Such cases in Kazakhstan are the earthquakes of Bakanasskoye(1979,M=14,I=6~7)and Zaysanskoye (1990,M=7.0,K=16,I=8).Besides,there are territories that are platforms in tectonic aspect,but which have been undergone activization at neotectonic evolution stage (Mangishlak,Ariskum desert near the Aral sea).Their potential seismic hazards are not estimated in General Seismic Zoning Map(GSZ-78).Mentioned circumstances induce the necessity to compile new seismic zoning map.
