Landslide hazard assessment of the Norak region of Tadjikistan

Introduction. The application of geographic information system (GIS) technologies is a promising technology for mapping and evaluating landslide hazards. At present, satellite-based terrestrial sensing widely used. Satellite images make it possible not only to identify individual landslides, particularly in hard-to-reach areas, but also those locations where processes have manifested, are manifesting may manifest themselves the future. Aim. Mapping present propagation territory Norak region Tajikistan using satellite imaging GIS. Materials methods. In course study, maps were compiled both automatically manually. An analysis results previous studies interpretations was conducted. Digital models relief, as well topographic, geomorphological, engineering geological maps, investigated. Results. A detailed map phenomena GIS format database created first time Republic Tajikistan. Conclusions. conducted zoning showed that, out total number, 24%, 36%, 10%, 18% 12% correspond very small, medium, large, large respectively. developed across area 2601×104 m2, which accounts 4% district. demonstrate that approach used this study be applicable hazard assessment poorly studied regions.
