Simulation of the Avaj earthquake 2002 by semi-empirical Greenʹs function

The Avaj earthquake in June 22, 2002 with a magnitude of Mw=6.5 occurred in western north of Iran. The requirement characteristics for modelling of strong ground motion such as length and wide of fault plate, strike, dip, focal position, stations position and etc. is defined by field study. These parameters are used in order to generate artificial earthquake based on the semi-empirical Greenʹs function methods for Avaj, Bahar, Kabudar Ahang, Shirin Su and Bakandi stations. Then, some parameters such as peak ground acceleration, effective duration, acceleration response spectrum and root mean square error of the generated earthquake compared with the real records. In this paper, semi-empirical Greenʹs function method is further developed for Iran condition. The results of the study are shown that the method can be applied for the other region with the fault of same mechanism such as Tehran faults.
