Abstract

Intensive excavation of slopes for land use and infrastructure development has taken place in Backan town. Consequently, landslides are very frequent in rainstorms, threatening the safety of residents at home and on roads. In the 132 km2 area of Backan town, significant landslide hazards are distributed in distinct strips, zones and points as a result of geological setting, weathering crust, soil and rock properties, topography and excavation for development. This study assesses the relative risk from landslides in Backan town to residents and transportation infrastructure. Vulnerable elements and resilience factors are investigated by field survey and questionnaires. The analyses of natural and social conditions in the GIS platform of Arc-GIS® enable a zonation of relative risk from landslide of residents and transportation infrastructure at 4 levels: low; medium; high and very high.
