Collaborative research: RUI: Seismicity and 3-D velocity structure of Lo`ihi submarine volcano

该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。洛伊希火山是一座活跃的海底火山，也是夏威夷岛链中最新的火山。作为夏威夷火山活动海底阶段的唯一例子，洛伊希火山为了解年轻热点火山的演化和活动提供了绝佳的机会。然而，尽管人们对Lo 'ihi的形态、岩石学、化学和微生物学有了大量了解，但以往对Lo 'ihi地震活动性和内部结构的研究受到数据质量差或缺乏仪器的阻碍。因此，我们对被描述为世界之一的世界的理解存在重大差距。美国研究最透彻的海底火山。该项目的主要目标是通过在火山上安装海底地震仪网络来调查海底Lo 'ihi火山的地震活动和内部结构，以进行Lo 'ihi地震活动的首次高分辨率研究，包括其内部结构的详细二维层析成像。该项目是一项试点研究，旨在进一步了解Lo 'ihi，最终对该地区进行主动式和被动震源相结合的地震研究，对Lo 'ihi及其周边地区进行全面的三维层析成像研究，并对该海底火山与夏威夷羽流之间的联系进行成像。一种上升的热物质柱，被认为是夏威夷火山活动的原因。本研究更广泛的影响集中在本科生的研究和教育上。本科生将参与项目的各个层面，从在游轮上担任看守，到参与数据质量控制和数据分析。作为他们研究经验的一部分，本科生将担任地球物理学入门课程的客座讲师，向他们的同龄人讲授地震分析。他们的工作最终将在地方或国家会议上展示他们的研究成果。该项目的数据也将用于领导机构的地球物理学入门课程。两名硕士生和一名博士后也将参与该项目。同样重要的是，西华盛顿大学主要是一所本科院校，该项目将支持一名早期职业女性研究者。

This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).Lo`ihi is an active submarine volcano and the newest volcano in the Hawaiian Chain. As the only example of the submarine phase of Hawaiian volcanism, Lo`ihi represents an excellent opportunity to understand the evolution and activity of a young hot spot volcano. However, while a great deal has been learned about Lo`ihi's morphology, petrology, chemistry and microbiology, previous studies of Lo`ihi seismicity and internal structure have been hindered by poor data quality or a lack of instrumentation. Consequently, there is a major gap in our understanding of what has been described as one of the world?s best-studied submarine volcanoes. The primary goal of this project is to investigate earthquake activity and the internal structure of the undersea Lo`ihi volcano by installing a network of ocean bottom seismometers on the volcano to perform the first high resolution study of Lo`ihi's seismicity, including a detailed 2-D tomographic image of its internal structure. The project is a pilot study to learn more about Lo`ihi with the goal of eventually performing a combined active and passive source seismic study of the region to perform a full 3-D tomographic study of Lo`ihi and the surrounding area and image the connection between this submarine volcano and the Hawaiian plume ? a rising column of hot material that is thought to be the cause of volcanism in Hawaii. The broader impacts of this study focus on undergraduate research and education. Undergraduates will participate at all levels of the project, from serving as watchstanders on the cruises, to participating in data quality control, and analyzing data. As part of their research experience, the undergraduates will act as guest instructors in introductory geophysics courses, teaching their peers about seismic analysis. Their work will culminate in the presentation of their research at local or national conferences. Data from the project will also be used in introductory geophysics curricula at the lead institution. Two masters students and a postdoctoral fellow will also participate in the project. Also significant are the fact the Western Washington University is a principally undergraduate institution and that this project will support an early career female investigator.
