IODP南海海槽地震孕育区实验（NanTroSEIZE）将首次尝试对俯冲带内板块边界断层或巨型逆冲断层的地震孕育部分进行钻探、取样和仪器测量。进入活动断层内部，在那里可以监测现场过程，并可以采样新鲜的断层带材料，这对理解地震力学具有根本的重要性。正如2004年12月苏门答腊地震和印度洋海啸悲剧性地表明的那样，大型俯冲地震是地球上最大的自然灾害之一。因此，在活跃的板间孕震区钻探和安装仪器是IODP初步科学计划（2001年）的一个非常高的优先事项。通过长达十年的一系列国家和国际研讨会，人们达成了共识，即南开海槽是尝试钻探和监测孕震板块界面的理想场所。NanTroSEIZE钻井作业的第一阶段现已定于2007年夏末进行。它涉及新的美国科学海洋钻探船（SODV，本卷）和立管钻探船Chikyu的平行部署。
The IODP Nankai Trough Seismogenic Zone Experiment (NanTroSEIZE) will, for the fi rst time ever, attempt to drill into, sample, and instrument the seismogenic portion of a plate-boundary fault or megathrust within a subduction zone. Access to the interior of active faults where in situ processes can be monitored and fresh fault zone materials can be sampled is of fundamental importance to the understanding of earthquake mechanics. As the December 2004 Sumatra earthquake and Indian Ocean tsunami so tragically demonstrated, large subduction earthquakes represent one of the greatest natural hazards on the planet. Accordingly, drilling into and instrumenting an active interplate seismogenic zone is a very high priority in the IODP Initial Science Plan (2001). Through a decade-long series of national and international workshops, a consensus emerged that the Nankai Trough is an ideal place to attempt drilling and monitoring of the seismogenic plate interface. The fi rst phase of NanTroSEIZE drilling operations has now been scheduled for the late summer of 2007. It involves parallel deployment of both the new U.S. Scientifi c Ocean Drilling Vessel (SODV, this volume) and the riser drilling vessel Chikyu.
