Map of earthquake epicenter density of Mongolia for the instrumental period (1964 - 2000) is presented. Seismic active zones are studied using information provided by the location of earthquake epicenters density. The results suggest that Mongolian territory could be divided into five seismic active and homogeneous sub- zones originated by the distribution of seismic active Cenozoic faults and epicenter density. Earthquake epicenter density and its spatial distribution are given a possibility to define and localize seismic active zones, current seismic pattern and its future dynamics of seismic activity in these zones. Most of earthquakes with the larger magnitude in the seismic active zones occurred in proximity to the statistically identified potential faults. Results of this study would be input parameters of seismic hazard assessment study of urban areas.
