sand_geo - Geologic attributes of the coastal zone of Sand Island (Oahu), Hawaii

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.
