In this study, images from the Sentile 2 satellite have been used. In the study, the proximity of the images was taken into account to minimize the error due to changes in gray scale. Also in this study, GIS and remote sensing data and SNAP software were used as tools.According to the subsidence zones obtained in the study area, it is observed that the maximum amount of subsidence around the tomb of Sheikh Mohammad is between 80-90 mm per year of landslide. The results show that the highest rate of subsidence in the study area is due to agricultural use and irrigated agriculture in the region. This problem may be mainly related to the issue of groundwater extraction for agriculture and drinking, and possibly other factors such as geology and tectonics. The centralization of the maximum rate of subsidence in residential areas has led to relatively insecure living conditions for the inhabitants and increased their vulnerability to land hazards. Also, considering the results of the steps taken to study the phenomenon of land subsidence in the study area, it is concluded that the phenomenon of land subsidence has a significant relationship with the grain size and with the lowering of the water table. Therefore, the combination of radar interference methods with high spatial resolution with high spatial resolution, satellite positioning systems with high temporal satellite positioning systems with high temporal resolution, and precise alignment with very high accuracy, is a good way of to study the movement of the earth's surface.
