Abstarct: For a long time, human has always been facing natural wrecking phenomenon and tried to find solutions to deal with them. Among these phenomenon, earthquakes have had the more destructive role in their lives. Once in a while, The earthquake has threatened the lives of thousands of people; It has destroyed many man-made structures and installations, and caused a lot of human and financial losses. Since the earthquake, as a natural disaster, has caused many losses in the human history, it is vital to evaluate the risk of earthquakes in the earthquake-prone areas. For this purpose, the strong ground movement parameter for the maximum horizontal acceleration component is estimated baxsed on the maximum earthquake that the faults in 150 km radius from the Miami Fault can cause. This is helpful to identifying hazardous seismic areas and accordingly, applying to retrofit and design-controlling of the existing and future structures. According to the calculations, the most seismic acceleration values at the center of a radius of 150 kilometers zone around Miami, are near the city and in the northwest of the province. The maximum calculated horizontal acceleration in the study area is located around Miami, Hokm-Abad and Ermian faults, which are 0.70, 0.70, and 0.35 gravitational acceleration (G), respectively. The main seismic epicenters within a radius of 150 kilometers from the city of Miami are Miami, Hakam-Abad and Ermian faults, which are representing seismicity of Ms = 8, Ms = 8 and Ms = 7.9 individually. Other epicenters in the region create the most of the seismic acceleration in this area.
According to the seismic acceleration map of the studied area, the maximum acceleration of the active faults in Miami is estimated as an average of 0.4g, which indicates that 63% of the area is classified in the high and very high risk of seismicity.
