Abstract: 
Salt domes are one of the most beautiful natural phenomena. Despite the outcrops of many salt domes in the Zagros region, but many of them are still buried and hidden. Due to active Zagros tectonics, the movement and ascending trend of salt domes do not stop. In this research, with the aim of the changes monitoring in the Earth's crust in the Zagros area, one of the new, hidden and ascending probabilistic salt domes, was identified using a radar interferometry method. For this purpose, ASAR radar images for the years 2007 and 2012 and SENTINEL-1 for the years 2014 and 2017 were used. In order to determine the amount of changes in the earth's crust, during the process of unwrapping on the images, the interference of each of the images was extracted. According to the results of the analysis of ASAR images, the growth rate of the salt dome was 1. 6 centimeters per year between 2007 and 2012. While according to the interferometry images that obtained from SENTINEL-1 the rising speed of this salt dome increased between 2014 and 2017, reaching 2. 9 centimeters per year. The result of this study shows that the probabilistic salt dome is active. Consequently, due to the importance of salt domes in various fields of natural resources, especially in the formation of oil reservoirs in the Zagros region, as well as more accurate identification of the subject, it is necessary to carry out special geophysical studies in this area.
