My major research objectives are to characterize and quantify spatial and temporal patterns of temperature, pressure, chemistry, and phase (e.g. liquid or gas) in volcano-hydrothermal systems and relate them to magmatic and/or volcanic activity. In these hydrothermal systems, aqueous and gas-rich fluids are a source of hazard (e.g., propellant in steam-driven explosions, lubricant in mudflows, toxic gases and dissolved constituents), a resource (e.g., geothermal energy and mineral deposits), and a potential indicator for one of the earliest warnings of unrest. Many of the geochemical, geodetic, and seismic signals measured at the ground surface have hydrothermal origins or magmatic origins modulated by the intervening hydrothermal system. This research is intended to support the USGS Volcano Hazards Program’s broad goal of lessening the harmful impacts of volcanic activity and the USGS Geothermal Project goals of exploring and developing technologies that will allow us to tap into reservoirs of geothermal heat that are known to exist in the Earth’s crust.
