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始终存在的危险，不仅是其直接破坏，而且对全球航班、贸易和经济发展造成破坏。虽然火山爆发后对岩浆过程的岩石学研究是可能的，但目前还没有办法将当今的火山监测技术与岩浆管道系统的理解联系起来，以及它对火山危机之前和期间火山爆发的持续时间、规模和震级的影响。这一建议旨在建立一个多学科的地球科学家小组，试图将上地壳应力状态（压缩、伸展、张拉）的地球物理观测与岩浆储存条件的岩石学推断联系起来。一旦建立起来，这个小组将在精心挑选的已知处于不同压力状态的目标火山上进行岩浆上升和喷发所需时间的初步数据收集。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步数据，建立一系列地壳应力-岩浆作用原型，并在世界各地的火山弧上进行测试和应用。有可能在未来，根据火山应力原型和对上部地壳应力状态的远程观测，可以更好地预测监测不佳的火山的动荡和喷发之间的时间尺度。

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.
