Volcanic and Epeirogenic Consequences of Plume-Lithosphere Interaction beneath Hawaii and Passive Continental Margins

大多数火山活动发生在沿着板块边界，沿着大洋中脊和火山弧。广义上讲，在这些环境中火山活动的原因是了解的，而在板块内部发生的大量火山活动的原因仍然不清楚。该项目将通过数值和模拟（物理）模拟相结合的方法，检验新的假设，即沿着夏威夷岛弧和沿着某些大陆边缘的板内火山活动是由地幔物质的上升羽流和上覆岩石圈之间的相互作用引起的。这一结果将有助于研究岩石圈与下伏地幔的相互作用。该项目将导致更好地了解夏威夷火山活动，其中有广泛的公众利益。更广泛的影响公开讲座，这一主题和培训学生的数值方法和地球动力学数值模拟。

Most volcanism occurs along plate boundaries, along mid-ocean ridges and volcanic arcs. Broadly speaking, the causes of volcanism in these setting is understood, while the causes of the lee voluminous volcanism that occurs in plate interiors remain obscure. This project will test the novel hypothesis that intraplate volcanism along the Hawaiian Arch and along some continental margins is caused by interactions between rising plumes of mantle material and the overlying lithosphere by a combination of numerical and analog (physical) modeling. The results will shed light on the interaction of the lithosphere and the underlying mantle. This project will lead to better understanding of Hawaiian volcanism, in which there is broad public interest. Broader impacts public lectures on this topic and training of students in numerical methods and geodynamic numerical modeling.
