Abstract
The metropolis of Tehran is the political and commercial capital of Iran. The city accommodates approximately 15 per cent of the nationwide population and hosts many important industries and infrastructures of the region. Thus, disaster mitigation and management are of great importance in Tehran. From the tectonic point of view, Tehran is located in the southern part of the central Alborz mountains belt in the northern part of Iran. The Alborz mountains belt is in the Alps–Himalayan organic zone. This region is known to have high potential for seismic activities because it has many active faults, including the Mosha, the North Tehran and the South/North Rey fault. Therefore, hazard mitigation studies for decreasing earthquake damage severity are necessary. One of the most important hazard programs is an effective earthquake early warning system. In this system with using new tools and methods tried to establish EEWS System. some activity including installation and operation of the system of monitoring stations, as well as the promotion of information and communication systems done Which for the first time in one of the metropolises at risk of damaging Earthquake (Tehran). Key Objectives * - Notification of the occurrence of the earthquake and thus protect the lives of citizens - Performance the rapid and technical reactions such as cutting off the flow of gas and fuel, etc., and consequently preventing secondary losses and damages - Protect of critical infrastructures in the city and accordingly take possibility to use them after the earthquakes
