| 摘 要： | 旨在探究剥蚀型汇聚板块边缘大地震成因机理的国际综合大洋钻探(IODP)344航次于2012年10月23日至12月11日在中美洲地震频发的哥斯达黎加西部海域实施钻探。介绍了钻探区域的大地构造特征、该航次的主要科学目标、执行情况、所取得的初步成果以及对航次后研究工作的展望等。航次后更多深入细致的研究工作正在进行中,所取得的研究成果将集中在2014年南京召开的航次后学术研讨会上汇报、交流、集成、总结,从而提升对剥蚀型汇聚板块边缘大地震起源机理的认识。 |

| Abstract: | Integrated Ocean Drilling Program (IODP) expedition 344 was implemented from October 23 to December 11, 2012 in the offshore Costa Rica, which is known for the frequent occurrence of earthquakes. This expedition is part of the Costa Rica Seismogenesis Program (CRISP) that has an overarching goal of elucidating the origin, nucleation, and propagation of earthquakes in an erosive convergent margin. We participated in this expedition. Here we present numerous aspects of this expedition in this paper including tectonic settings of the drilling area, major scientific goals, field operation, preliminary results of this expedition, and post-cruise activities. More detailed and much in-depth research is carried out after the cruise and post cruise results will be reported in the meeting to be held in Nanjing University in 2014. The synthesis of these new results should lead to better understanding of the seismogenesis of the study area. |
