This award supports an ongoing U.S.-Japan collaborative research project between John Beavan and Chris Scholz of Lamont-Doherty Geological Observatory, Columbia University, and Teruyuki Kato, Earthquake Research Institute, University of Tokyo. This project is part of a five-year collaboration to resolve several major problems related to the active tectonics of the Philippine Sea Plate and its boundaries through collection and analysis of Global Positioning System (GPS) measurements at sites strategically placed along the eastern, western, and northern boundaries of the Philippine Sea Plate in southeast Japan, the Ryukyus, Taiwan, and in the Bonins, Marianas, and Micronesia. During the two-year period of the grant, the following specific topics will be addressed: (1) determination of accurate Philippine - Eurasian Plate and Philippine Sea-Pacific poles and rotation rates; (2) the magnitude of plate driving forces at trench boundaries; (3) the mechanism of back-arc spreading; (4) the mechanism of strike-slip in the forearc; (5) the mechanics of arc-continent collision; and (6) the distribution of deformation and seismic hazard in southeast Japan and Taiwan. In addition to the principal investigators, others involved in the project are Dan Davis, SUNY Stony Brook; Steven Roecker, Rensselaer Polytechnic Institute; Kazuro Hirahara and T. Tanaka, Kyoto University; and I Murata, T. Kato, and S. Nakao, University of Tokyo. This grant complements a grant from the NSF Earth Sciences Program, which is funding the research in the United States.

该奖项支持哥伦比亚大学拉蒙特-多尔蒂地质观测站的 John Beavan 和 Chris Scholz 以及东京大学地震研究所的 Teruyuki Kato 正在进行的美日合作研究项目。 该项目是一项为期五年的合作的一部分，旨在通过收集和分析位于日本东南部、琉球群岛、台湾以及小笠原群岛、马里亚纳群岛和密克罗尼西亚群岛的菲律宾海板块东部、西部和北部边界战略位置的全球定位系统（GPS）测量结果，解决与菲律宾海板块及其边界活动构造有关的几个主要问题。 在资助的两年期间，将解决以下具体课题：（1）准确确定菲律宾-欧亚板块和菲律宾海-太平洋极点和自转速率； (2) 沟槽边界处板块驱动力的大小； (3)弧后扩展机理； (4)弧前走滑机制； (5)弧陆碰撞力学； (6) 日本东南部和台湾地区变形和地震危险性的分布。 除了主要研究人员之外，参与该项目的其他人还包括纽约州立大学石溪分校的丹·戴维斯 (Dan Davis)； Steven Roecker，伦斯勒理工学院； Kazuro Hirahara 和 T. Tanaka，京都大学；我是东京大学的 Murata、T. Kato 和 S. Nakao。 这笔赠款是对美国国家科学基金会地球科学计划赠款的补充，该计划正在资助美国的研究。
