This database consists of a series of maps showing tsunami inundation based on historical events (1946 Aleutian, 1952 Kamchatka, 1957 Aleutian, 1960 Chile, and 1964 Alaska tsunamis) and hypothetical events (two great Aleutian earthquakes with moment magnitude (Mw) 9.3 and 9.6 as potential sources). 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.

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).

Please read ‘Description-Map of Tsunami Inundation.docx’ for detailed information.

[Metadata] Description: TMK Parcels for the State of Hawaii - 2025; specific dates vary by county. Sources: County of Hawaii: 5/16/25; County of Maui: 5/30/25; City and County of Honolulu: 6/3/25; County of Kauai: 6/2/25. Hawaii Statewide GIS Program projected to a common projection/datum (UTM Zone 4, NAD 83 HARN) and merged all counties' parcel data into one layer. Where necessary, the State standardized field names or added fields to the county layers such as creating text fields for corresponding numeric tmk fields, etc., and / or calculated values for fields such as links to qpublic.com websites showing additional information for each parcel. The parcel boundaries are intended to provide a visual reference only and do not represent legal or survey level accuracy.

[Metadata] Flood Hazard Areas for the County of Honolulu - downloaded from FEMA Flood Map Service Center, May 1, 2021. The National Flood Hazard Layer (NFHL) data incorporates all Flood Insurance Rate Map (FIRM) databases published by the Federal Emergency Management Agency (FEMA), and any Letters of Map Revision (LOMRs) that have been issued against those databases since their publication date. It is updated on a monthly basis. The FIRM Database is the digital, geospatial version of the flood hazard information shown on the published paper FIRMs. The FIRM Database depicts flood risk information and supporting data used to develop the risk data. The primary risk classifications used are the 1-percent-annual-chance flood event, the 0.2-percent-annual-chance flood event, and areas of minimal flood risk. The FIRM Database is derived from Flood Insurance Studies (FISs), previously published FIRMs, flood hazard analyses performed in support of the FISs and FIRMs, and new mapping data, where available. The FISs and FIRMs are published by FEMA. The NFHL is available as State or US Territory data sets. Each State or Territory data set consists of all FIRM Databases and corresponding LOMRs available on the publication date of the data set. The specification for the horizontal control of FIRM Databases is consistent with those required for mapping at a scale of 1:12,000. This file is georeferenced to the Earth's surface using the Geographic Coordinate System (GCS) and North American Datum of 1983.For additional information, please summary metadata https://files.hawaii.gov/dbedt/op/gis/data/s_fld_haz_ar_state.pdf or contact Hawaii Statewide GIS Program, Office of Planning and Sustainable Development, State of Hawaii; PO Box 2359, Honolulu, Hi. 96804; (808) 587-2846; email: gis@hawaii.gov; Website: https://planning.hawaii.gov/gis.
