Background and objective: Due to heavy toll in recent years, great economic and social vulnerability of urban areas to earthquake hazards has been particularly noticeable. However, there has been little progress made in minimizing the impact of this natural disaster.While predicting the earthquake with precision is beyond our current knowledge and ability, in order to tackle the potential casualties as a result of destructive earthquakes, an Earthquake Early Warning System can significantly reduce the possible death toll.

Method: Using CDF (Probability Cumulative Distribution Function) this study aims at investigating the extent to which this Earthquake Early Warning System is implemented for the Tabriz city that it is located on North Tabriz Fault so as to predict the time of Onsite warning and Regional warning in a probabilistic manner. To find out the areas subject to risks of earthquakes, earthquake simulation by using stochastic method, the peak ground motion of the earth, were calculated for the Tabriz.

Conclusion: The results of this study shows that it is not possible to establish considerable On-Site warning by for Tabriz. It seems that this amount of time to set up Earthquake Early Warning Systems in the city of Tabriz, under 10 seconds, in terms of economy, cost, time and energy, according to the existing station arrangement will not be economical.
