A rockfall susceptibility based on trajectory-energy/velocity approach needs release area or rockfall source. However, identification of rockfall source is not always possible for some areas in Indonesia. This paper presents a rockfall susceptibility zoning based on back analysis technique of rockfall deposit inventory in Gunung Kelir, Java. There were several steps in the rockfall susceptibility zoning: (1) rockfall deposit inventory, (2) rockfall simulation based on back analysis of rockfall deposit inventory, (3) sensitivity analysis, and (4) rockfall susceptibility zoning. The result suggests that the travel distance is affected by the spatial distribution of rockfall source, lithology or surface material, and topography (angle of slope and angle of aspect). Final trajectories were employed to generate landslide susceptibility map which may allow a policy maker to have an advanced consideration to achieve specified risk measures and evaluation of their cost efficiency to optimize budget and design. Application of rockfall susceptibility zoning based on back analysis of rockfall deposits is efficient where rockfall source information is unavailable. 相似文献

Central Java Province, Indonesia, suffers from natural hazard processes such as land subsidence, coastal inundation, flood,
volcanic eruption, earthquake, tsunami, and landslide. The occurrence of each kind of natural hazard is varied according to
the intensity of geo-processes. It is necessary to learn from the historical record of coastal inundation, flood, volcanic
eruption, earthquake, tsunami, and landslide hazards in Central Java Province to address issues of comprehensive hazard mitigation
and management action. Through the understanding about the nature and spatial distribution of natural hazards, treatments
can be done to reduce the risks. This paper presents the natural hazard phenomena in Central Java Province and provides critical
information for hazard mitigation and reduction. 相似文献
