Natural hazards have always changed the environment and threatened human life. In this regard, geological hazards including earthquake, subsidence, etc. are the most destructive natural factors that our country, Iran, is affected by them. That is why planning and preparation to deal with these catastrophes is essential. Aerial communication networks have an important role in the relief operation because of the rapid access after an earthquake. The purpose of this study, is locating an appropriate site of air rescuing after a casualty. Hierarchical analysis method was used for weighting after determining the effective indicators in locating; including the area of open space of the site, access to dense and vulnerable texture, service user and main arteries. After preparing the final map, zones of avoidance were announced. The evaluation method similarity to ideal option in the software environment of the spatial information system was used to select the final site. This study is an applied research because of its aim and it has been carried out using descriptive - analytical method. According to obtained results, three squares called Sanat, Saheb-a Zaman and Farhang were selected as suitable sites. Sanat square was identified as an appropriate site because of having the highest score according to defined criteria
