Latest map of observed runup heights, compared with NOAA modeled heights

Map of American Samoa, showing field locations where the ITST measured runup heights October 5-6, 2009. Values are not tide-corrected, and the scale of the figure precludes showing all of the details of the observed spatial variation in runup. Locations of some of the higher runups are shown.
