Summary

This data release is comprised of a set of eight time travel map shapefiles (two tsunami inundation zones and four travel times) for use in GIS software applications and two population exposure by travel time tables (residents and nonresidences) for use in GIS software applications and other standalone spreadsheet applications. The travel time map was generated using the Pedestrian Evacuation Analyst model (version 1.0.1 for ArcGIS 10.5) from the USGS (https://geography.wr.usgs.gov/science/vulnerability/tools.html). The travel time analysis uses ESRI's Path Distance tool to find the shortest distance across a cost surface from any point in the hazard zone to a safe zone. This cost analysis considers the direction of movement and assigns [...]

Purpose

The objective of these data is to aid in characterizing population vulnerability to tsunami hazards in American Samoa based on fatality demographics and observations of evacuee behavior from the 2009 disaster, projection of probable maximum tsunami hazards in the area, and pedestrian evacuation modeling. This information provides direct assistance to tsunami-planning efforts in American Samoa but also provides insight on evacuation behavior and population vulnerability to other coastal communities throughout the world that are threatened by local tsunami hazards.
