The first maps showing volcanic hazard zones on Hawai‘i Island were prepared in 1974 by U.S.
The published Lava-Flow Hazard Zone Map (paper copy) was not intended to be used at a scale necessary to identify individual parcels on the map. However, digital mapping software can offer new options for this determination:
The Lava Flow Hazard Zone map was designed for general planning purposes only. The following statement is included on the published map (USGS Miscellaneous Field Studies Map 2193):
An option is to contact the State of Hawai‘i Department of Commerce and Consumer Affairs. The USGS Lava-Flow Hazard Zone Map is meant to convey relative volcanic hazard rather than risk (see “Hazard vs. Risk” below).
An option is to contact the State of Hawai‘i Department of Commerce and Consumer Affairs. Their Website states that they investigate insurance-related complaints.
While the USGS prepared and made available the Lava-Flow Hazard Zone Map for general information and planning by land-use managers, there is no legislation requiring its use.
Lava-flow hazard zones reflect the long-term hazard of lava flows, not the short term hazard. Rate of lava coverage—not how recently lava covered an area—is the basis of long-term lava flow hazard.
The following two papers contain more detailed information about Hawaii lava-flow hazards:
