Gibbs, A.E. 2002 U.S. Geological Survey Geologic Investigations Series I-2761 Menlo Park, California U.S. Geological Survey http://pubs.usgs.gov/imap/i2761/ Coastal Slope along the coastal zone of Hawaii, Hawaii The purpose of this dataset is to provide, in digital format, the information included in the technical hazard maps published in the 'Atlas of Natural Hazards in the Hawaiian Coastal Zone' (Fletcher et al., 2002) for use by citizens, scientists, and regulatory agencies. Data included here were derived from the technical hazard maps published in the 'Atlas of Natural Hazards in the Hawaiian Coastal Zone' (Fletcher et al., 2002) The atlas reports on a program of research that assigns a relative ranking scale to seven natural coastal hazards. The ranking is based on the historical trends and natural factors influencing site vulnerability and hazard intensity in the Hawaiian coastal zone. Information contained within the Atlas is largely based on previous investigations by scientific and engineering researchers and county, state, and federal offices and agencies. The unique aspect of this report is that, to the extent possible, it assimilates prior efforts in documenting Hawaiian coastal hazards and combines existing knowledge into a single comprehensive coastal hazard data set. It is by no means the final word on coastal hazards in Hawaii. Every hazardous phenomenon described, and others such as slope failure and rocky shoreline collapse, need to be more carefully quantified, forecast, and mitigated. The technical hazard maps were constructed for the entire shorelines of the islands of Kauai, Oahu, Molokai, Lanai, Maui, and Hawaii at a scale of 1:50,000 (1 inch on the map equals approximately 0.8 miles). The technical map series displays the nominal relative intensity (on a ranked scale of 1 to 4, where 4 is most intense; overall hazard assessment is on a ranked scale of 1 to 7, where 7 is most intense) of each of the seven hazards following a set of specific definitions. Any use of trade, product, or firm names is for descriptive purposes only and does not imply endorsement by the U.S. Government. Although this Federal Geographic Data Committee-compliant metadata file is intended to document the data set in nonproprietary form, as well as in ESRI format, this metadata file may include some ESRI-specific terminology. 1994 2002 publication date Complete as needed -156.19 -154.64 20.33 18.83 USGS Metadata Identifier USGS:24601a23-714c-4bfa-9f82-7712bc848557 None Hawaii island slope coastal coast ISO 19115 Topic Category oceans geoscientificInformation Marine Realms Information Bank (MRIB) keywords coast coastal plain geomorphology USGS Thesaurus land surface characteristics geomorphology Coastal and Marine Ecological Classification Standard (CMECS) Continental/Island Shore Complex None Hawaii Oahu Molokai Lanai Maui Kauai Pacific Island Coastal and Marine Ecological Classification Standard (CMECS) Hawaii Ecoregion Coastal and Marine Ecological Classification Standard (CMECS) Substrate none USGS-authored or produced data and information are in the public domain from the U.S. Government and are freely redistributable with proper metadata and source attribution.

The line file was subset into separate lines for each island, and the topology was then "cleaned up" using an ESRI sample script.
