摘要: Disaster mitigation and reconstruction plan due to tsunami can be implemented with various actions. An integration of spatial analysis through Geographical Information System (GIS) application and multi-criteria Analytical Hierarchy Process (AHP) is one the methods for inundation impact assessment. In this study, vulnerability, assessment hazard in Ofunato city, Iwate Prefecture, Japan was carried out. Appropriate input parameters were derived from Digital Elevation Model data, satellite remote sensing field data were analyzed GIS. We applied the parameter of elevation slope created Aster GDEM version 2, coastline distance vector map study area vegetation density ALOS ANVIR-2 image. AHP process weighting the parameter pair-wise comparison using five iterations normalized matrix. Five classes vulnerability were defined analyzed mapping. We used weighted overlay analyst in GIS create final map of vulnerability. The results indicate that 7.39 square kilometer of under high zone tsunami, 8.13 square kilometer building area. Our result showed good agreement observed historical map. presented here aid as preliminary information for coastal management related disaster mitigation evacuation management strategy during disaster.
