چکیده مقاله:

One of the quickest and most efficient methods to study urbanism conditions and determine critical conditions of regions and rate of losses after earthquake is the use of aerial photos. Thecritical conditions are more severe in cities and mountainous regions due to the steep slope of traffic routes, snow and frosting,and use of aggregates. Using satellite images and GIS maps different regions were classified into three categories. The zoningwas based on the route, slope, materials, construction, and population density, as well as the map of facilities, power lines, water and wastewater networks, and gas pipes. The criticalconditions for each region were defined numerically and the resulting figures were summed up based on the maps of differentzones. However, each figure was assigned to a certain portion of the map. With an increase in the number of maps with different zonings, the critical areas and figures changed.
