A coastal vulnerability index was used to map the relative vulnerability of the shore to future sea-level surge within National Park of American Samoa. The CVI places the adhering to in terms of their physical contribution to sea-level rise-related coastal change: geomorphology, local seaside slope, rate of relative sea-level increase, historical coastline change rates, suggest tidal range and indicate significant wave height. The National Park of American Samoa includes carbonate sand and coral reefs debris beaches, rock cliffs and platforms, and back-reef shallows shorelines. The areas within National Park of American Samoa that are likely to be most at risk to sea-level increase are areas of unconsolidated sediment where seaside slope is shallowest and wave energy is high.
