Population increasing and irregular Immigration to Tehran, which followed by developing construction, has been increased the hazard exposure of the city of Tehran. In addition, historical urban spreading of Tehran, and surrounding by the important active faults, increase the risk of earthquake consequence. After a destructive earthquake,  a capital city such as Tehran encounters to fire, subsidence, water leakage and failure of many services. Earthquake early warning system as a solution of risk reduction has been proposed in recent decades. A limited number of countries such as Japan, America, Mexico, Romania, have almost applied this system and some countries such as Turky, Korea, China, and Italy are developing EEWS. This paper was conducted for examination of the possibility or impossibility of using the earthquake early warning system of Tehran. Consequently a feasibility study of theoretical network has been investigated. Also sensitivity analysis of some EEWS parameters has been done. Finally, according to the Tehran’s active faults, we concluded that it is possible to provide alarm time for many destructive earthquakes.
