In the framework of investigation the deductive probabilistic approach of hazard assessment has been applied to the Moldova Republic territory for reviewing the present seismic zoning. The main results presented in this paper are the MSK-intensity and PGA-acceleration maps for 500, 1000 and 10 000 years return periods.
