Dr. Donald Thomas
Geochemistry and hydrology of geothermal systems and ocean islands, Volcanic gases, Radon release and transport
Ph.D., University of Hawai'i at Mānoa
+1 808 956 6482


Research Interests:
Geochemistry and Hydrology of geothermal systems; Structural Controls on the Hydrology of ocean islands; Chemistry of volcanic gases and their relation to the state of unrest of active volcanoes, Radon release and transport.

Current Projects:
Recently completed two continuously-cored research boreholes in the Humu’ula Saddle of Hawai’i Island and a third continuously-cored observation hole in the LĀna’i Caldera region in an effort to define hydrogeological conditions in these regions and to document groundwater chemistry as affected by underlying thermal activity.

I also serve as the Director of the Center for the Study of Active Volcanoes, housed at University of Hawaii at Hilo campus. That program currently offers an annual summer training course on Volcano Hazards Assessment and Monitoring that is designed for volcano professionals from developing nations. CSAV also maintains a Cooperative Agreement with the USGS Volcano Hazards Program that supports a Hawai’i-based natural hazards public outreach program.
