In this study, the analysis of physical and social vulnerability for tsunami risk assessment was<br>applied for tsunami mitigation activities in coastal areas. The analysis was applied in the southern coastal<br>area of East Java, Indonesia. The application of Geographical Information System (GIS) was used to capture,<br>store, manipulate, analyze, manage, and visualize geographic data used for tsunami risk analysis. GIS makes<br>possible in integrating a complex layer of the geographic phenomenon and the parameter of tsunami<br>vulnerability. In this case, the spatial overlay of physical and social vulnerability was done using spatial<br>multi-criteria approach. Physical vulnerability parameters analyzed in this study were elevation, slope, land<br>use, and distance from the coast. While the social vulnerability parameters include the number of population,<br>age distribution, number of women, and people with disabilities. The results described the visualization of<br>possible damage and loss areas that may result from a tsunami attack. The analysis illustrated that the most<br>vulnerable areas of the tsunami were areas with low elevation, very sloping slopes, areas that close enough to<br>the coastline and the land use type of residential class. The areas with high vulnerability class also illustrated<br>by social vulnerability parameters especially population density. The estimates of affected areas due to<br>tsunamis can help the decision-makers in mitigating the possible consequences of tsunamis, managing the<br>emergency response related to the tsunami disaster, and developing plans for recovery and reconstruction<br>after the tsunami event.</p> ER -
