Abstract

EARTHQUAKEs can make lots of disruptions in activities of a country. It can fail traffic system by disrupting communication system, disconnection of the supply chain of materials and emergency services. It also can make serious obstacles to safety of EARTHQUAKE victims. This dangerous situation is because of narrow streets, constructing high-rise buildings in old urban segments, wrong positioning of tall building, constructing building in the seismic belts and path of the Qanats in Tehran. Thus, these factors increase congestion in large cities, damages and casualties because of EARTHQUAKEs. The aim of this study is to assess the VULNERABILITY of communication network in the urban area due to different seismic intensity. For this reason, ten effective criteria were selected and applied in ANP models within the fuzzy language. Then, selected GIS layer were combined for pre-disaster stage. In next session, forecasting model was implemented for different intensity as 6, 7, 8 modified Mercalli scale as a pre-disaster VULNERABILITY plan. The results of study show that the VULNERABILITY of pedestrian network in district 3 for 6 mercalli is around low and very low for 53 percentages of the area while the highest VULNERABILITY was assigned to Seyed Khandan and North-Kavoosiyeh with 64%. In the scenario with intensity of & mercalli 53% of pathways were suffered from high VULNERABILITY. In the scenario with 8 mercalli, the VULNERABILITY of pathways in two states of high and full-destruction had been ascending trend. Around 80% of pathways are in these to states. The highest vulnerabilities were assigned to district number 6, 1, 2, 3, 5 and 4 according to their rates.
