Development of Stability Criteria for Risk Reduction in the Sianok Canyon in Bukittinggi Indonesia

The development of Sianok Canyon area as a tourist destination in Bukittinggi-Indonesia also needs a disaster risk reduction to be included in. The city already has land use plan that restricts the development around the upper part of the Canyon. This restriction is not equally effective because it has no consideration based on the actual thinking. The study that provides a scientific consideration is needed since the city has limited land. Then, the geological study and geotechnical investigation was done to obtain required data. It is followed by the potential landslide analyses of the Canyon area. Furthermore, based on the results of the analyses the safety factor and safe distance criteria are proposed for consideration in the development plan of the city as well as to reduce the disaster risk.
