There are four parameters which are used to determine of tsunami vulnerability areas in a thematic map. The parameters are distance of beach, topography, vegetation, and shape of shore. The results of the research are three categories of area of tsunami vulnerability that are the heavy area of tsunami vulnerability, medium, and safety area.
