- Summary:
- As conceived in a 1990 proposal to Congress by the State of Hawaii, the Hawaii Geothermal Project would involve the development of a geothermal resource for electrical power production within three legislatively-defined (Act 296, Session Laws of Hawaii, 1983) geothermal subzones on the east rift zone of Kilauea volcano. The project would include overland transmission of this power to the west coast of Hawaii. From there to Oahu, the power would be transmitted principally via submarine cable. In this report, lava geothermal subzones and the three proposed overland transmission routes. The time interval for evaluating hazards was chosen as 50 years because that is consistent with seismic design standards in the Uniform Building Code, and because of limited information on occurrence dates. The geothermal subzones and the first leg of the overland transmission routes are located on the east rift zone and northeast flank of Kilauea Volcano. Kilauea is an active volcano that has been erupting continuously from vents a few kilometers west of the western geothermal subzone. The overland transmission routes then continue across the northeast flack of the active volcano Mauna Loa and the dormant volcano Mauna Kea to their ultimate destination on the western flank of the extinct volcano of Kohala. Neither Mauna Kea nor Kohala have been active in the past several thousand years.
