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.

为主要研究人员（PI）提供资金参与一个项目，该项目旨在研究断层系统演化时控制断层连续性、应变分区以及多个断层分支之间相互作用的动力学。具体来说，拟议的工作将重点关注北安纳托利亚断层（NAF）北部和中部分支之间不断变化的关系。为了评估描述这种关系的一系列可能的模型，该项目将使用已经为北部分支收集的高分辨率多道地震（MCS）数据，并将为中央分支收集新的MCS数据。这些数据将与建模相结合，以表征滑动历史、应变分区和相关断层活动。结果将限制 NAF 系统的演化，并能够与其他转换故障系统进行比较。资金将允许 PI 最初参与土耳其研究巡航。更广泛的影响：拟议的工作对于了解土耳其的地震危害具有直接影响，并且还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。 PI 将继续开展持续的外展工作。数据管理包括在采集/分析后两年内将数据归档到各个存储库中。
