Summary

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.

Purpose

These data were collected as part of a large research project that examined the impacts of climate change, sea-level rise, storm waves, and tsunamis on avifauna and their habitat in the Northwestern Hawaiian Islands. Collected data included a wide range of physical data (coastlines, digital elevation models, bathymetry, predicted wave run-up from storm waves, tsunami high water marks), habitat data (land cover classifications, vegetation maps and monitoring plots), and biological survey data (bird abundance and density, nest census, and habitat surveys). The purpose of this dataset was to determine the extent to which avifauna nesting sites and nesting habitat were inundated during the tsunami event. We assumed that all habitat between the high water mark and the shoreline were inundated during the tsunami event.
