Environmental abilities and limitation with seismic and how Zanjan population Centers establishment analysis

Zanjan has many faults due to its severe tectonic activity in geology areas. According to conducted studies on Zanjan, this county has three separated areas in earthquake occurrence term including high danger widths, average danger widths and low danger widths. This research main aim is Zanjan population main centers seismic spatial analysis. In this case uses ultra-available plans and present documents to analyze Zanjan active faults and mentioned county seismic widths. In continue study how establish and disperse population main residential places (Zanjan villages and cities). Finally by using ArcGIS software analytical abilities and layers overlapping analyzes how establish county cities and villages regarding to county seismic widths. Conducted studies revealed that of 22000 km2 Zanjan area 45% widths have high earthquake danger, 47% average and only 8% low danger. How disperse county cities and villages points according to 1390 census has shown 1015734 population in 7 counties, 16 parts, 16cities, 46 villages and 961 rural areas. By using ArcGIS software and layers overlapping has analyzed earthquake danger spatial analysis in population main center. Results reveal that of 16 urban residential places in Zanjan, 12 cities have placed in high earthquake danger width. Also of 46 villages, 25 ones are in high danger, 18 in average and 3 in low danger areas. Considerable share of burgess population are living in high earthquake danger widths. As of 626760 individual of burgess population 93.01 % area in high danger areas. 5.4% are in average and 1.5% in low danger areas. Earthquake danger spatial analysis in villages show that in county villages 52% population are in high danger, 41% in average and 7% in low danger widths. Also of 46 villages, 25 ones are in high danger, 18 in average and 3 in low danger areas.
