Blind geothermal system exploration in active volcanic environments; multi-phase geophysical and geochemical surveys in overt and subtle volcanic systems, Hawaii and Maui

Abstract

This project targets a ‘blind’ volcanic system on the southwest flank of Maui, Hawai’i –unconventional due to volcanic dormancy and lack of surface thermal manifestation. Assessing unconventional targets requires re-tooling the standard geothermal exploration kit and adding in new tools. Our research will do the following: • Provide a benchmark for exploration of other ‘blind’, dormant volcanic systems • Validate gravimetry and aeromagnetics for geothermal exploration in young, basaltic volcanic environments • Demonstrate use of CO2, isotope analysis and hyperspectral imaging in young, hot-spot volcanic systems for geothermal exploration • Provide baseload energy for Maui island.
