Laysan Island inundation area during 2011 tsunami

This GIS shapefile delineates the approximate inundation extent on Laysan Island during the March 11, 2011 tsunami event that originated off the Tohoku coast of Japan. The high water mark was created from a GPS track file of the debris line taken on March 12, 2011, the day after the tsunami. The coastline at the time of the tsunami was estimated based on the location of the coastline as viewed in a satellite image taken approximately 10 months before the tsunami(May 18, 2010). The inundation extent was estimated as the polygon area bound by the coastline and high water mark.
