The 7.8 M earthquake occurred in south east Iran on 16 April 2013 at 10:44:20 UTC. This earthquake was the most massive earthquake in last 50 years, with tremors felt across Pakistan, Oman and UAE. According to BHRC (Iranian Building and Housing Research Center) report, this event was recorded by 33 digital accelerographs in Iran Strong Ground Motion Network. The peak acceleration was recorded in Sabz Gazz seismic station. This study presents simulation of near-field ground motions of the 2013 Iran earthquake. For this purpose, five seismic stations are selected to simulate ground motions using semi-empirical approach. Hamzehloo and Mahood (2012) attenuation relationship for south east Iran is used to obtain acceleration waveformenvelope function. Acomparison is done on characteristics of observed and simulated ground motions. The simulated results are satisfactory at many of the seismic stations. It is concluded that higher frequencies (2-10 Hz) of simulated ground motions match with observed ground motions.
