Volcanic eruptions are an ever-present hazard facing society both in terms of their immediate devastation, but also global disruption to flights, trade and economic development. While petrological insights into magmatic processes are possible following an eruption, as yet there exists no way to link present day volcano-monitoring techniques to an understanding of the magmatic plumbing system, and its effects on the duration, size and magnitude of the volcanic eruptions prior to and during volcanic crises. This proposal seeks to establish a multidisciplinary team of Earth scientists to attempt to link the geophysical observations of upper crustal stress state (compression, extension, transtension) with petrological inferences of magma storage conditions. Once established, this team will look to undertake some initial data collection of the time it takes for magma to rise and be erupted, at carefully selected target volcanoes which are known to be in different stress states. Longer-term, this new team of experts will look to use the initial data collected from this Global Partnerships Seedcorn Fund to establish a series of crustal stress-magmatism archetypes to be tested and applied at volcanic arcs worldwide. There is potential that in the future, timescales between unrest and eruption at poorly-monitored volcanoes could be better anticipated based on volcanism-stress archetypes coupled with remote observations of upper crustal stress states.
