Abstract

In Azerbaijan, development of landslide hazard areas is occurring at a greater rate than in previous years. Mass movements (landslides, Mass wasting) may take place suddenly and catastrophically, resulting in debris and snow avalanches, lahars, rock falls, flows (debris, quick clay, loess and dry or wet sand and silt) .The region under survey is located in a valley named “ILANJIG”. Its slope is about 30 to 40 percent and the main road of Tabriz- Sarab- Ardebil is routed across this valley. This valley is a Fault Valley and residual signs of old landslides can be observed along the valley. Construction of Tabriz- Ardebil main road was started in 1991 and completed in 1997. Because of poor design of the road, and due to continuous penetration of rain and water from melted snow into the mass clay layers and its volume swelling, shear strength of clay decreased and heavy loads from upper volcanic rock blocks lead to sudden fracture and resulted in a huge landslide. Approximate volume of main landslide was [1.6x106]/0.2[m3/km2]. Landslides are the most predictable geological hazards, among other natural hazards.

Mass Movement Landslide (June 10, 2005) Along Sarab- Ardebil Main Road (West Slope Savalan Volcanic Mountain)- Azerbaijan- Iran
