Hydro-petrology of Earth's most explosive volcano

Arguably the most influential and enigmatic element for creating volcanic processes on planets is hydrogen.  Over the past 7 years, one research focus area of my group has been understanding the hydro-petrology of Shiveluch volcano in Kamchatka, the most explosive volcano in the world, using data collected from erupted material and high pressure and temperature experiments conducted in the ESPM lab.  In this talk, I will present new data and experiments that highlight our current and evolving conception of hydrogen’s role in subduction zone settings on Earth.  I will also discuss how our experiments and petrographic work inform our understanding of the plumbing system under Shiveluch and highlight future directions of our research on this important topic.
