Collaborative Research: The North Anatolian Fault system in the Marmara Sea, Turkey - Insights from the Quaternary evolution of a multi-stranded transform

资金提供的主要研究人员（PI）参加一个项目，旨在调查动态控制故障的连续性，应变分区，以及多个故障分支之间的相互作用，作为故障系统的演变。具体而言，拟议的工作将侧重于北安纳托利亚断层（NAF）的北方和中央分支之间不断演变的关系。为了评价一系列描述这种关系的可能模型，该项目将使用已经为北方分支收集的高分辨率多道地震数据，并将为中央分支收集新的多道地震数据。这些数据将与建模相结合，以表征滑动历史，应变分区和相对断层活动。结果将限制NAF系统的演变，并使与其他转换断层系统的比较。更广泛的影响：拟议的工作对了解土耳其的地震危险有直接影响，也可能支持该地区未来的IODP倡议。它将通过与土耳其研究人员的持续合作加强国际联系。主要研究员将继续开展外联工作。数据管理包括在采集/分析后两年内将数据存档在各种储存库中。

Funds are provided for the principal investigators (PIs) to participate in a project that aims to investigate the dynamics controlling fault continuity, strain partitioning, and interaction between multiple fault branches as fault systems evolve. Specifically, the proposed work will focus on the evolving relationship between the northern and central branches of the North Anatolian Fault (NAF). To evaluate a series of possible models describing this relationship, the project will use high-resolution multi-channel seismic (MCS) data already collected for the northern branch, and will collect new MCS data for the central branch. The data will be combined with modeling to characterize slip history, strain partitioning, and relative fault activity. Results will constrain the evolution of the NAF system and enable comparisons with other transform fault systems. Funds will allow the initial participation of the PIs on the Turkish reserach cruise.Broader Impacts: The proposed work has direct implications for understanding seismic hazards in Turkey, and may also support a future IODP initiative in the area. It will strengthen international ties through ongoing collaboration with Turkish researchers. The PIs will continue ongoing outreach efforts. Data management includes archiving of data in various repositories within two years of acquisition/analysis.
