项目摘要
Volcanic eruptions pose one of the principal hazards at tectonically active continental margins, such as the Pacific northwestern United States, which are of ever increasing economic and existential importance to expanding populations. The project will enhance knowledge of the conditions that lead to eruptions of silica-rich magmas, which can be large and impactful. Furthermore, it will boost understanding of the fundamental processes that determine the progression of volcanic eruptions, from inception to cessation, which remains difficult to forecast. Consequently, the project transcends the purely academic and is societally relevant by advancing natural hazard assessment capabilities. The project supports education by enabling the interdisciplinary training of graduate and undergraduate students as well as a postdoctoral scholar, thus contributing to the development of a diverse and globally competitive workforce.The project's objective is to advance fundamental knowledge of how volcanoes work by simulating a volcanic eruption from initial explosive activity through lava effusion, to termination of the eruption and post-eruptive inflation, using the 2011/12 Cordon Caulle eruption in Chile as a case study. For this eruption the run-up, the syn-eruptive evolution, and the post-eruptive reconfiguration of the volcanic system were documented in unprecedented detail. The project is multi-disciplinary and encompasses geochemistry, petrology and geodesy, in addition to numerical simulation of magma storage and eruption. The project is multi-institutional -- the portion of the project at Cornell University focuses on geodesy and numerical simulations in collaboration with the other institutions. New observational data will be acquired and integrated with existing observations in order to simulate the eruptive progression of the eruption. The eruption was initially explosive and over time eruption rates decreased with activity shifting from purely explosive to effusive, resulting in the formation of a large lava flow and shallow laccolith. The current view about these types of eruptions is that effusive or explosive activity are possible under otherwise identical conditions and with potentially rapid transitions from one to the other. A goal of the project is the assessment of conditions resulting in transitions in eruptive activity in order to test this explosive-effusive bistability hypothesis. Rapid post-eruptive inflation was observed and a further goal is to assess the extent to which the system has been driven back toward a critical state. These goals will be achieved by integrating the different observational data within extensive physics-based model simulations that will lead to improvements in model reliability and further our understanding of underlying processes at Cordon Caulle and similar hazardous volcanic systems elsewhere.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
火山喷发是构造活动活跃的大陆边缘(例如美国西北部太平洋地区)的主要危害之一,这些地区对不断增长的人口的经济和生存重要性日益增加。该项目将加深人们对导致富含二氧化硅岩浆喷发的条件的了解,这种喷发可能是大规模且具有影响力的。此外,它将增进对决定火山喷发从开始到停止的进程的基本过程的理解,而火山喷发仍然难以预测。因此,该项目超越了纯粹的学术范畴,通过提高自然灾害评估能力而具有社会意义。该项目通过对研究生和本科生以及博士后学者进行跨学科培训来支持教育,从而有助于培养多元化和具有全球竞争力的劳动力队伍。该项目的目标是通过模拟火山来提高火山工作原理的基础知识以 2011/2012 年智利 Cordon Caulle 火山喷发为例,研究从最初的爆炸活动到熔岩流出,到喷发终止和喷发后的膨胀。对于这次喷发,火山系统的预备期、同步喷发演化和喷发后的重新配置都得到了前所未有的详细记录。该项目是多学科的,除了岩浆储存和喷发的数值模拟之外,还包括地球化学、岩石学和大地测量学。该项目是多机构合作的——康奈尔大学项目的一部分重点是与其他机构合作进行大地测量和数值模拟。 将获取新的观测数据并将其与现有观测相结合,以模拟火山喷发的过程。喷发最初是爆炸性的,随着时间的推移,喷发率随着活动从纯粹的爆炸性转变为喷发性而降低,导致形成大量熔岩流和浅层石岩。目前对这些类型喷发的看法是,在其他相同的条件下,可能会发生喷发或爆炸活动,并且可能会从一种喷发迅速过渡到另一种喷发。该项目的目标是评估导致喷发活动转变的条件,以测试这种爆炸-喷流双稳态假设。观察到爆发后的快速通货膨胀,进一步的目标是评估系统被推回临界状态的程度。这些目标将通过将不同的观测数据整合到广泛的基于物理的模型模拟中来实现,这将提高模型的可靠性,并进一步加深我们对 Cordon Caulle 和其他地方类似危险火山系统的基本过程的理解。该奖项反映了 NSF 的法定使命和通过使用基金会的智力价值和更广泛的影响审查标准进行评估,该项目被认为值得支持。
