Natural disasters such as earthquakes can cause irreparable damage to humans and the environment. Earthquakes are considered as natural disasters that cause many human and financial losses every year. Today, with the advancement of science and technology, suitable grounds have been provided for recognizing and reducing these natural hazards. Therefore, risk assessment is critical for proper management and reduction of losses. Risk assessment is determined by the process of estimating the probability of an event occurring, and the importance or severity of its adverse effects. The aim of this study was to assess the vulnerability of Bushehr province to earthquake risk. In this regard, by combining fuzzy and hierarchical logic models using GIS software, the vulnerability of Bushehr province to earthquake risk has been analyzed and extracted. Effective indicators in earthquake vulnerability are: distance from the fault, earthquake epicenter, earthquake magnitude, earthquake depth, land slope and lithology. The results show that 23% of Bushehr province, which is mostly located along faults, are very vulnerable in the danger zone.
