Abstract

The most fundamental issues for local people who are potentially at risk to tsunami threat are awareness and preparedness. The aim of this paper is to define the effectiveness of tsunami evacuation routes toward tsunami hazard along the coast of Lampung bay. The parameter applied in this study were elevation and slope created based on Aster GDEM while the coastline distance was made based on vector map and tsunami inundation obtained by Hills and Mader equation. In addition, the road network was derived from Development Planning Agency at Sub-National Level. AHP process was applied in determining the weight of the parameter by using pair-wise comparison via five normalized matrix iteration. Thus, there are five vulnerability classes that were classified. Weighted overlay through spatial analysis in geographic information system (GIS) was used in this study in order to make the final tsunami vulnerability map. The Network Analysis through Closest Facility Analysis in GIS was used to create the effective evacuation route and to point out 34 effective evacuation locations that could be reached by the people before the tsunami strikes. The results presented in this paper could eventually facilitate the improvement in the basic data for city planning related to evacuation process and management strategy during disaster
