This polygon layer delineates the area inundated during the March 11, 2011 tsunami. It is based on a tracking file generated by Pete Leary, of US Fish and Wildlife Service, who traversed the high water mark (debris line) of the tsunmai on March 15, 2011. The coastline at Midway Atoll, which changes from year to year and season to season, was taken from the last available image (Jan. 14, 2010) prior to the tsuanmi event. The tsunami inundation area represents the area bound by the high water mark and the coastline.
