对发震带试验计划(SEIZE)以及南海（Nankai）海槽的发震带钻探计划（NanTroSEIZE）进行了综述。SEIZE作为大陆边缘计划(MARGINS)的重要研究内容和综合大洋钻探计划（IODP）的优先研究领域，重点对世界主要俯冲发震带进行研究。SEIZE的主要研究内容包括：①凸凹体的物理性质；②在地震周期里，应力、应变和孔隙流体成分随时间的变化；③在俯冲逆冲断层上，发震带上界和下界的确定；④引起海啸的发震带的特征；⑤大型逆冲带地震在物质转换过程中所起的作用。NanTroSEIZE将成为IODP第一个基于立管钻探的计划，也是科学大洋钻探历史上第一个分期实施的复合钻探计划；钻入发震带的复合钻探计划将最终验证关于发震带的各种假说。

This paper gives a brief introduction to the Seimogenic Zone Experiment (SEIZE) and Nankai Trough Seismogenic Zone Experiment (NanTroSEIZE). As one of major initiatives of the NSF-MARGINS Program and Integrated Ocean Drilling Program (IODP), SEIZE focuses its research on major subduction seismogenic belts in the world. The main study areas of SEIZE include: (1)physical nature of asperity; (2)temporal relationships among stress, strain, and pore fluid pressure throughout the earthquake cycle; (3)controls on the updip and downdip limits of the seismogenic zone of subduction thrusts; (4)nature of tsunamigenic earthquake zones; (5)role of large thrust earthquake in mass flux. As the first riser drilling proposal, NanTroSEIZE was highly ranked. It is also the first complex drilling proposal in the history of scientific ocean drilling program. Drilling through the seismogenic zone based on this complex drilling proposal will provide evidences to validate many hypotheses of the seismogenic zone.
