  Ghir-Karzin city is in the southeastern Fars province. In this research by using satellite images, length ongestionmap, cross section, and number of lineation and map of the earthquakes focus in the region were prepared andthen by obtaining indices of mountain’s Facet outcrop amount (in percentage), mountain’s facet meander (Smf),and length-stream index (SL) on the three anticlines Changal, Palang and Afzar, of tectonic activities rates ofthese anticlines have been investigated. The results obtained from these indices, in addition to being presented inthe tables, for much better representation and analysis, have been shown as a numerical model and a profile aswell. . Combination of the obtained data from the map of fractures, indices’ numerical model, map of epicenters,and drainage profiles indicates that the region’s anticlines are active, i.e. uplifting rate in the region is higher thanerosion rate. Finally, after study of the obtained results, the reason for high rate of tectonic activity in the easternsection of Changal anticline was found to be this anticline’s vergency towards south-west and increase of thefissure and fractures as a result of extensity in the northern top chord and pressure production in the southern topchord. In the western section of this anticline too, the high tectonic activity can be attributed to presence of theDarre siah Fault. High tectonic activity of Afzar anticline is due to presence of the active fault Ghir in north-eastof this anticline and the anomaly map of the fractures and epicenters confirm these results as well.
