Abstract: 
In the spring of 1374 a major landslide occurred in the hillside overlook the riverbed ‎near the Nasirabad village of Varzaghan City located 70km towards northeast of ‎Tabriz. It caused a heavy toll in Nasirabad. Therefore west part of the village ‎compared to the east part of it has four meters difference of level‏.‏‎
‎ The geological data and geomorphological factors effective in instability of this slope ‎were studied and on the basis of morphometric parameters factors effective in ‎instability of this slope were studied and on the basis of morphometric parameters, the ‎zonationplan of the landslide was drawn and its quantitative characteristics were ‎recognized. By analyzing active mechanisms in mass movements of material, security ‎ploms for its control were presented‏. ‏‎
‎ Field studies and geology, climatology, kind of soil, vegetation cover data and the use ‎of morphometric methods shows that the rain storms of the region and penetration of ‎surface water in to sediments in upper hillside such as, rumble and the very thickness ‎of surface on hillsides with average slope have been the main cause of landslide‏.‏
