Subseafloor Observatory Science in the Nankai Trough: Analysis of Earthquakes and Hydraulic Transients, and Installation of a Community Borehole Facility

本研究旨在分析南开俯冲杂岩（C0002）井眼的孔隙压力数据，建立一个互动门户网站，传播该井眼的数据，并对该井眼进行“引导”。在南开安装新的钻孔仪器。孔隙压力数据将与地震和应变测量相结合进行分析，以提供孔隙压力和地震应变之间的直接相关性。新的门户将连接到有线系统（DONET），并将实时向更广泛的社区提供所有钻孔数据。新的社区仪器井眼将跨越C0010井眼的一个斜断层，并连接到电缆系统，提供实时数据访问。更广泛的影响：新的数据门户将与宾夕法尼亚州立大学已经在课堂上使用的现有系统集成，允许本科生访问实时数据集。这项工作将提供有关潜在的海啸断层行为的信息。这项工作是国际范围的，并得到国际资金的高度利用。

This proposal seeks to analyze pore pressure data from a borehole in the Nankai subduction complex (site C0002), to develop an interactive portal to disseminate data from this borehole, and to ?shepherd? the installation of new borehole instrumentation at Nankai. The pore pressure data will be analyzed in concert with seismic and strain measurements in an effort to provide a direct correlation between pore pressure and seismic strain. The new portal will be connected to a cabled system (DONET) and will make all borehole data available to the wider community in real time. The new community instrumented borehole will span a splay fault in hole C0010 and also be connected to the cabled system, providing real-time access to data.Broader impacts: The new data portal will be integrated with an existing system already in classroom use at Penn State, allowing undergraduates access to the real-time data sets. The work will provide information regarding the behavior of potential tsunamigenic faults. The work is international in scope and highly leveraged by international funds.
