Volcanoes have played and continue to play a pivotal role in shaping human societies, both modern and ancient. From the eruption of Vesuvius to that of Eyjafjallajökull, volcanoes have killed hundreds of thousands of people and led to billions of dollars in economic losses. Forecasting these eruptions in order to mitigate their impact is thus of the utmost importance. While considerable progress has been made in quantitatively characterising volcanic eruptions, even the most advanced models suffer from a paucity of accurate data due to the difficulty inherent in their acquisition. Consequently, our understanding of the physical, chemical, spatiotemporal “boundary conditions” for the intrusion and migration of magma within the crust beneath volcanoes is still very limited. The proposed multi-faceted research program will enhance our ability to effectively characterize these magmatic systems via accurate modern and forensic geochemical and geophysical measurements of dormant and active volcanic systems.

火山在塑造现代和古代人类社会方面发挥了并将继续发挥关键作用。从维苏威火山爆发到埃亚菲亚德拉火山爆发，火山已造成数十万人死亡，并导致数十亿美元的经济损失。因此，预测这些火山爆发以减轻其影响至关重要。虽然在定量描述火山爆发的特征方面取得了相当大的进展，但由于获取数据的固有困难，即使是最先进的模型也缺乏准确的数据。因此，我们对火山下地壳内岩浆侵入和迁移的物理、化学和时空“边界条件”的了解仍然非常有限。拟议的多方面的研究计划将提高我们的能力，有效地通过准确的现代和法医地球化学和地球物理测量休眠和活动火山系统的特点，这些岩浆系统。
