Abstract: 

In recent years, landslide occurrence, due to change of forests into tea farms and construction of roads, has been on the increase in northern regions of Iran. The investigation of phenomena and factors, effective in landslide occurrence is vital and detern1ining susceptible zones for the purpose of preventing and avoiding the harmful consequences, is indispensable. There are several methods for landslide hazard zonation. In this research, the statistical method of multiple regressions was employed. For evaluation of accuracy of the model, a neighboring basin with similar lithology, land use, rainfall and other characteristics was chosen, the model being used for this basin. The results of the investigation showed that most recorded landslides in the area have occurred in zones marked as susceptible in the offered model. Therefore the use of the proposed and employed model for the study area was confirmed.
