Abstract
Regional assessment for geothermal potential in Hawaii indicated thermal alteration of shallow groundwater in northeast Maui. Studies within the area, the lower north rift of Haleakala volcano, include the measurement of ground Rn emanation, soil Hg concentration and soil pH. Anomalous results from these geochemical techniques are reasonably coincident, and are located over the western boundary of the rift structure. These studies suggest anomalous subsurface temperatures associated with the rift and consequent enhancement of ground gas outgassing. Further survey, both geochemical and geophysical, are currently begin carried out to confirm these conclusions.
