Abstract

Disaster is a series of events caused by human nature, or both resulting in casualties and human suffering, property damage, environmental damage, damage to infrastructures facilities, and public utilities as well as disturbance of the system raises the life and livelihood. Landslides (landslides) represents a comprehensive disaster in mountainous and hilly regions in the world, has led to loss of life and material damage. Factors causing landslides, among others: rainfall, steep slopes, soils that are less dense and thick, rock is less powerful, the kind of governance of land, vibration, and shrinkage of the water table by or dams, the extra burden, erosion / erosion, the embankment material on the cliff, the former long avalanche, the discontinuity field (field is not continuous), deforestation, waste disposal area. The problem in this research is only limited studies landslide-prone land in the lane Tanawangko-Tomohon Tomohon. Main purpose of this study was to determine the points of land landslide hazard on the road lane Tomohon-Tanahwangko benefits derived from this research is to be produced a study of geological and geomorphological conditions Tomohon-Tanawangko lane road. Variables to be studied, namely landslide, the physical condition of the study area, and the factors triggering the landslide of the most influential land. Identified three types of land landslide that occurred in Tomohon-Tanawangko lane road covering; collapse (fall), landslides (slides), and flow (flow). Avalanche land is most common creep (flow) of seven (7) points avalanches. Land landslide vulnerability study area was divided into four (4) landslide prone zones include; Low Land landslide-prone zones, landslide-prone zones Land moderate, high land landslide-prone zones, landslide-prone zones land is very high. Interval slope of each point landslide Land is at 44% -85%, so it can be seen that from every point of avalanches that are in landslide-prone zones landslide-prone zones of moderate to very high land.
