Figure 9. Vulnerability ranking for regional coastal slope of the National Park of American Samoa. The colored shoreline represents the regional slope of the land, 2 km landward and seaward of the shoreline. The low vulnerability areas with respect to coastal slope are primarily concentrated on Ta'u. Tutuila is moderate to high vulnerability, and Ofu and Olosega are mostly moderate to high vulnerability with a small area of low vulnerability along the north coast.
