Hawaii Map Series of Tsunami Inundation for the Ocean Hazards Database
Description
This database consists of a series of maps showing the estimated inundation of Hawaii shorelines caused by historically measured and hypothetically modeled Tsunami flow depths. Individual maps show inundation across mile-long sections of Hawaii state routes on the islands of Hawaii, Maui, Molokai, Oahu and Kauai previously identified for their vulnerability to the effects of climate change as part of the Statewide Coastal Highways Project Report. Tsunami inundation based on historical events observes the 1946 Aleutian, 1952 Kamchatka, 1957 Aleutian, 1960 Chile, and 1964 Alaska tsunamis; and hypothetical events consider two great Aleutian earthquakes with moment magnitudes (Mw) of 9.3 and 9.6 as potential sources. Mileposts are identified by Brandes et al. (2019). State of Hawaii Department of Transportation (HDOT) state routes and county street centerline datasets are acquired from HDOT (2017) and HOLIS, C&CH (2017). Shoreline datasets are provided by NGS (2017). Potential inundation areas are determined by the tsunami flow depth datasets reported in Cheung (2009, 2011, 2012, 2013, and 2015) with respect to mean higher high water (MHHW). Details on map datasets and their usage can be found in the 2019 State of Hawaii Statewide Coastal Highways Project Report.
