Landslide hazard zonation for landslides’ prevention

Landslide hazard zonation for landslides’ prevention

The wider area of Metsovo is characterized by geoscientists as a high landslide risk region. In this paper, the process of creating a map of landslide hazard zones of the wider region of Metsovo which shows three areas of risk for landslides, small, medium and high, using GIS methods and techniques, is described. The risk map is generated by linearly combined factors considered to contribute to landslide occurrence. These factors are: slope angle, lithology, vegetation cover, distance from the roads, distance from the river network, orientation of the slopes, topographical elevation. The map that was created can contribute to identify existing structures at risk from landslide activity and  may assist to allocate appropriate land uses to unstable terrain.
