Existing seismic hazard map (the map of seismic zonation) of the territory of Tajikistan was produced in 1978 (Babaev et al.,1978),renovated in 1984 (Seismic zonation…,1984),and has the seismic hazard estimation in the points of intensity of shaking in MSK-64 scale. In 1984 the new map of earthquakes source zones (ESZ) (map of seismogenic zones) was created (Babaev et al.,1984),but the new map of seismic zonation didnt create.This ESZ map based on the map of active faults and indicates the linear seismic sources with given maximum possible magnitudes.Note,the return period of earthquakes with given maximum possible magnitudes is at least 1/1000.Use this map of linear seismic sources location we calculate the PGA values distribution around the country with supposition that given maximum possible magnitudes identical for the whole line of active fault zone or segments of the fault zone.All active faults zones (seismic sources) are divided into six groups: with M=8; M=7.5; M=7; M=6.5,M=6,and M=5.5.
