  • Thomas, D.M.; Gudmundsson, J.S. (Hawaii Institute of Geophysics / National Energy Authority, 1989)
    The International Workshop on Deposition of Solids in Geothermal systems was held in August 1988. Papers were presented on field and laboratory studies of scale deposition from geothermal fluids and in geothermal reservoirs. ...
  • Thomas, Donald M.; Sakai, Hitoshi (Fourth International Symposium on Water-Rock Interaction, 1983-08)
    "The HGPA well, located on the Lower East Rift Zone of Kilauea Volcano, was drilled in 1976. It is completed to a depth of 1966 m 1768 m below sea level and has a bottom hole temperature of approximately 360C. The well is ...
  • Thomas, Donald M. (Hawaii Institute of Geophysics and Planetology, 1994-03-18)
    The geochemical monitoring program has undertaken two related responsibilities: 1) Conduct a detailed analysis of the chemistry and dynamics of the shallow groundwater system on the Lower East Rift (LERZ); and 2) Evaluate ...
  • Thomas, Donald M. (U.S. Geological Survey, 1987)
    The east rift zone of Kilauea Volcano is comprised of a northeast- to southwest-trending complex of dikes and fractures extending more than 100 kilometers from the summit caldera to the ocean floor. Geologic, petrologic, ...
  • Thomas, Donald M. (Hawaii Institute of Geophysics, University of Hawaii at Manoa, 1988)
    Studies of earthquake precursory phenomena during the last several decades have found that significant geophysical and geochemical changes can occur prior to intermediate and large earthquakes. Among the more intensely ...
  • (1990)
    Laboratory analysis report by the Department of Health, State of Hawaii.
  • (Hawaii Institute of Geophysics, University of Hawaii, 1980)
    A regional geothermal resource assessment has been conducted for the major islands in the Hawaiian chain. The assessment was made through the compilation and evaluation of the readily accessible geological, geochemical, ...
  • Gardner, Murray C.; McNitt, James R.; Klein, Christopher W.; Koenig, James B.; Nakano, Dean A. (International Geothermal Association, 1995-05)
    "Government-funded surveys of the Kilauea East Rift Zone have resulted in a wealth of geophysical and geochemical data from an active volcanic area. All data are clearly of academic interest; Hawaii was used as a testing ...
  • Thomas, Donald M. (Hawaii Institute of Geophysics, School of Ocean and Earth Science and Technology, University of Hawaii, 1992-06)
    U.S. DOE Grant No. DE-FG07-88ID12741. A series of experiments was performed to investigate methods of controlling silica in waste geothermal brines produced at the HGP-A Generator Facility. Laboratory testing has shown ...
  • (Republic Geothermal, Inc., 1978-07-01)
    Project objectives and research progress are briefly summarized for solar energy, biomass, hydrogen, and geothermal energy research projects.
