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.

该提案旨在分析南开俯冲复合体（地点 C0002）钻孔的孔隙压力数据，开发一个交互式门户来传播该钻孔的数据，并“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。新门户将连接到有线系统（DONET），并将所有钻孔数据实时提供给更广泛的社区。新的社区仪器钻孔将跨越 C0010 孔的张开断层，并连接到有线系统，提供对数据的实时访问。更广泛的影响：新的数据门户将与宾夕法尼亚大学课堂上使用的现有系统集成国家允许本科生访问实时数据集。这项工作将提供有关潜在海啸断层行为的信息。这项工作的范围是国际性的，并受到国际基金的高度利用。
