In risk analysis, parameters such as distance, height, attenuation relationships, local soil conditions, etc. are used, and a certain parameter of the ground movement in the desired site is predicted. The effects of future earthquakes cannot be determined exactly, and these effects can only be partially predicted with probabilistic methods. Earthquake (seismic) risk analysis includes research and methods that can be used to estimate the effects of future earthquakes on construction. These effects mainly include ground motion parameters. In the past, the earthquake intensity parameter was used due to the lack of earth movement measurement tools. In this study, a probabilistic seismic hazard analysis was performed considering the effects of the aftershocks of the Naqadeh earthquake (July 18, 2021) and compared with the conventional analysis results. The results of the analysis show the importance of aftershocks in the estimation of seismic risk and the necessity of considering these events as part of the seismic risk of the region.
