Spatial Analysis of Evacuation Sites for Tsunami Mitigation in Banyuwangi City

Banyuwangi, a coastal region south of East Java, faces a potential tsunami risk due to tectonic activity in the Java subduction zone. The vulnerability of densely populated coastal regions necessitates the development of a comprehensive disaster mitigation strategy that includes identifying and providing sufficient evacuation sites. This study aims to assess the availability, spatial distribution, and capacity of tsunami evacuation sites in Banyuwangi City. The methods used include Geographic Information System (GIS)-based spatial analysis, tsunami hazard map analysis, and field observations at potential shelter sites with weighting analysis. The results show that several temporary evacuation sites or existing shelters are available. However, their distribution is uneven, and their capacity remains limited compared to the number of affected residents. This study recommends adding shelters in high-risk areas, enhancing evacuation routes, and integrating spatial planning with tsunami risk maps. These findings are expected to act as a reference point for local governments and communities in enhancing their tsunami preparedness.
