NI MagmaStress: Quantifying the effect of crustal stress states on the style and timing of magmatism in the Southern Volcanic Zone, Chile

火山爆发是社会面临的一个永远存在的危险，不仅直接造成破坏，而且对全球航班、贸易和经济发展造成破坏。虽然火山爆发后，岩石学对岩浆过程的洞察是可能的，但目前还没有办法将现代火山监测技术与对岩浆管道系统及其对持续时间的影响的理解联系起来，这一建议旨在建立一个多学科地球科学家小组，试图将地球物理观测与地球物理观测联系起来，上地壳应力状态（压缩、伸展、张扭）与岩浆储存条件的岩石学推断。一旦成立，该团队将在精心挑选的已知处于不同应力状态的目标火山上收集岩浆上升和喷发所需时间的初步数据。从长远来看，这个新的专家团队将利用从全球伙伴关系种子基金收集的初始数据来建立一系列地壳应力-岩浆作用原型，以在全球火山弧中进行测试和应用。有可能在未来，动荡和火山喷发之间的时间尺度监测不良的火山可以更好地预测的基础上火山应力原型加上远程观测上地壳应力状态。

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.
