The purpose of this research is to develop a physical model of the cities of Mazandaran province using morphometric indices of active tectonics, which was conducted based on a case study of settlements between Shirgah and Galugah. In this study, five indices of hierarchical anomaly, bifurcation, basin shape, drainage density, and relative prominence were calculated in 15 drainage basins between these two counties. The results of this study, based on morphometric indices, show that most of the settlements in Mazandaran city, including residential areas from Shirgah to Galugah, corresponding to the faults of North Alborz, Khatir Kooh, Dazdbon, and Marzanabad, have high and very high morphometric indices due to the influence of the aforementioned faults. About 33.3% of the area is dominated by the activity of these faults. In addition to the main faults, other minor faults formed by recent tectonic movements present moderate to high tectonic activity. The location of these settlements in the vicinity of these faults has also increased the seismic risk of the region. Due to the history of earthquakes in this region and the proven tectonic activity of the region, the risks from earthquakes must be considered in the construction of civil infrastructure.
