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.

该项目的目标是为巽他俯冲带制作古地震记录，其中包括在2004年地震期间破裂并造成苏门答腊海啸的那一段。将采用多种技术将浊积岩与地震事件联系起来：将回收岩芯并研究生物地层学、磁性和同位素记录，并进行碳测年。PI已经沿着卡斯卡迪亚边缘进行了沿着类似的研究，并取得了一些成功。计划在2008财政年度对R/V梅尔维尔进行一次研究巡航，以收集必要的数据。这项研究具有重要的社会意义，因为研究结果将有助于危害评估。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。
