IDENTIFICATION OF LANDSLIDE DISASTER PRONE SETTLEMENTS IN MADIUN REGENCY BASED ON GEOGRAPHIC INFORMATION SYSTEM
Abstract
Landslides are natural phenomena that often occur in mountainous or highland areas. Landslides can be caused by several factors, such as rainfall, slope, soil type, geology and land use. In addition, landslides can also occur due to human activities, such as deforestation, road construction, and settlements (Yulaelawati, E., 2008). Efforts to provide solutions and ease of disaster mitigation in settlements in Madiun Regency can be done by making a Landslide Hazard Map of Settlements. The map can be identified with a Geographic Information System (GIS) using the overlay method or overlay on several parameters, such as: slope, soil type, rainfall and history of landslide events. From the research that has been done, it can be concluded that the level of vulnerability to landslides in settlements in Madiun Regency is dominated by a low vulnerability level of 13398,04 ha; a medium vulnerability level of 848,78 ha; and a high level of vulnerability of 2,26 ha.
