Tsunami mitigation plan for Manakarra Beach of West Sulawesi province, Indonesia

Abstract

Due to the increasing activities of underwater earthquake along the Sulawesi's Waters past this one last decade, the development of future tsunami mitigation plan become important for Sulawesi Island. This research pin pointed to the easiness of the mitigation plan concept and the availability of the infrastructure. The development of this mitigation plan was based on future tsunami modeling of Manakarra Beach of Mamuju at West Sulawesi Province. TUNAMI N2 algorithm at SiTProS Ver 1.5 was used on the tsunami propagation modeling and based on Sulawesi Seismic System for tsunami generation. Tsunami run-ups and time impact interval as the modeling results, were used as basis to develop the tsunami mitigation plan for the Manakarra Beach. The evacuation scheme which put into map and module for the Manakarra Beach of Mamuju has been established in this research; with mainly based on a mass evacuation plan to the high buildings or high ground.
