Spatial Model of Coastal Community Vulnerability of Puger District to Tsunami Disaster Hazard

Abstract

Abstract Puger coastal region is prone to tsunami and earthquake disasters. Puger District lies in the coastal zone which is directly adjacent to the Indian Ocean. Village areas included in the Coastal District of Puger are villages of Puger Kulon, Puger Wetan, Mojomulyo, and Mojosari. The potential for tsunami disaster on Puger Beach can affect the safety of the coastal communities of Puger. The location of community settlements is close to the beach, with relatively poor understanding of the danger of tsunami. Moreover, the negligence of an established disaster mitigation plans for tsunamis in Puger coastal region causes high vulnerability in case of tsunami; hence, casualties and property loss can affect the economy of the surrounding community. Based on these conditions, the study aims to assess the level of social, economic, physical and environmental vulnerabilities modelled spatially to determine the level of vulnerability of the community with the aid of Arc GIS 10.2 software. The analysis method employs scoring analysis and spatial analysis. The research output is a spatial model in the form of a community vulnerability map to the threat of a tsunami disaster.
