The Mw 9.3 Indonesian Earthquake and the Holocene Great Earthquake Record from the Northern Sumatran Subduction Zone

该项目的目标是生成舜达俯冲带的古地震记录，其中包括在地震中破裂并在2004年造成苏门答腊岛海啸的那段。将采用各种技术将浊积岩与地震事件相关联：将回收岩芯，并对其进行生物地层学、磁性和同位素记录研究，并将进行碳测年。国际和平研究所在卡斯卡迪亚边缘进行了类似的研究，并取得了一些成功。2008财年计划在R/V Melville上进行一次研究巡航，以收集必要的数据。这项研究具有重要的社会意义，因为这项工作的结果将有助于危险评估。与印度尼西亚和日本的国际合作也将有助于该项目产生更广泛的影响。

The objective of this project is to generate a paleoseismic record for the Sunda subduction zone, which includes the segment that ruptured during the earthquake and caused the Sumatran tsunami in 2004. A variety of techniques for correlating turbidites with seismic events would be employed: cores will be recovered and studied for biostratigraphy, magnetic and isotope records, and will be carbon dated. The PI has undertaken similar studies along the Cascadia margin with some success. A research cruise on R/V Melville is planned for FY08 to collect the necessary data. The study has important societal relevance as the results of the work would benefit hazard assessment. International collaboration with Indonesia and Japan will also contribute to the broader impacts of the project.
