This proposal requests funding for a new initiative to constrain the development and evolution of large magma reservoirs in the Earth’s upper crust, and their potential rapid evacuation during large explosive volcanic eruptions (particularly the caldera-forming events of more than ~10 km3 of magma). The issue raised by this proposal concerns everyone: the next large volcanic eruption (with a =VEI 6) will leave a large impact on society, with many direct casualties, ripples of starvation world-wide, and a colossal economic impact. Hence, a fundamental task for the volcanological community is to determine which volcanic systems around the world store large amounts of eruptible magma that could be mobilized rapidly during an eruption.Using a combination of geochemical/petrological tools and numerical models, it is now possible to reach a more quantitative understanding of the reservoirs that feed those supereruptions. Geochemical/petrological data is readily available for large volcanic units and their smaller precursors. Such data now routinely provides valuable constraints on the state of the magma reservoir at the time of eruption. Hence it is possible to draw an evolution path for a given system when nearly complete stratigraphic column can be sampled. It is also now possible to run sophisticated predictive models to determine how magma reservoirs behave through time assuming a set of conditions determined by field and geochemical/petrological data. The goal of this proposal is (1) to compile field, petrological, geochemical and mineralogical data from units in several young volcanic systems with the potential for large explosive event, in different tectonic settings, in order to determine petrological patterns that help predict the development of a large, eruptible magma pool in the upper crust and (2) to run inverse and forward models of magma reservoir evolution to illuminate potential outcomes for a given set of conditions. Due to the inherent multi-disciplinarity of the project, a large group of collaborators and students with different scientific background has been assembled. Such a team will allow dynamic international exchanges and fruitful transfer of knowledge.
