The article considers the Ossetian sector of the Greater Caucasus from the point of view of studying its seismicity and analyzing seismic hazard assessments previously constructed at all levels of seismic zoning (GSZ, DSZ and SMZ). The areas prone to strong earthquakes identified by pattern recognition methods are discussed. The results of the analysis emphasized the high level of seismic hazard of the foothill and mountainous areas of the region. The description of seismic networks that continuously monitor the region is given. The analysis of the most representative earthquake catalog with a unified magnitude scale that was previously created by the authors, and spatial variations of the magnitude of full registration, showed that the level of registration of seismic events in the east of the Ossetian sector of the Greater Caucasus is still worse than in its central and western parts.
