Abstract: 
In the last several years periodic reports indicated the damages to resident"s homes due to ground movement in the Barikan region, 120 km away from Tehran. The earth movement demonstrated by tension cracks and scarps at the surfaces and cracks in the walls of homes and gardens. Maximum movement of village was occurred during the 1990 S Roodbar and Manjil earthquake, north of Iran. Since the slow and continuous earth movement has been observed in the site, a course of site investigation consisting the monitoring of surface and deep earth movement was considered to study the affecting factors and extent of landslide. In the assigned monitoring program, 15 pillars have been fixed around the surface of village, and during about 8 months at the different intervals of time, movement of each point was controlled with reference to a BM out of the moved part. The preliminanary, investigation showed that the rate of movements is a function of groundwater level, and decreased with lowering the groundwater level. Also the increase in width of tension cracks on the surface ground, and walls through the region measured periodically. Plaster plugs installed between concrete frames in depth of monitoring wells, in which any possible cracks reveal soil movement in depth. In addition to ground movement measurements, using the geotechnical properties of different soil layers, stability analysis of soil mass was performed. Results have shown that village would be stable at static conditions in all relative water level conditions. However, in case of earthquake with the value of horizontal acceleration at the pseudo static analysis equal to 0.14g, analysis indicated total instability of landslide. In this paper the results of conducted researches, as well as possible remedial measures to soil movements with regards to known responsible factors of landslide presented.
