The first maps showing volcanic hazard zones on Hawai‘i Island were prepared in 1974 by U.S. Geological Survey geologists and were published in USGS Open-File Report 74-239. The lava-flow hazards map was reformatted in the 1980s, based on new and more complete geologic mapping and lava flow age-dating by USGS scientists.
In 1992, the Lava-Flow Hazard Map was slightly revised and published as USGS Miscellaneous Field Studies Map 2193
