Annotation:
The results of seismic microzoning of the territory of Vladikavkaz City held in 2011 are considered. Basing on the results of detailed seismic zoning and macroseismic investigation of the past earthquakes the reference soil (the average ground conditions) in the form of unsaturated clayey soils of medium-hard consistency was determined. The initial intensity (seismicity) of the territory equal to 8 points is attributed to this soil. The intensity increments for sites with typical soil conditions were estimated by means of instrumental, analytical and instrumental-analytical methods of seismic microzoning. The corresponding seismic microzoning map of Vladikavkaz in terms of macroseismic intensity units in the scale of 1:10000 was created.
