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

为主要调查人员(PI)提供资金，以参与一个项目，该项目旨在研究随着故障系统的演化，控制故障连续性、应变划分和多个故障分支之间相互作用的动力学。具体地说，拟议的工作将侧重于北安纳托利亚断层(NAF)北部和中部分支之间的演变关系。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。这些数据将与模拟相结合，以表征滑动历史、应变分配和相对断层活动。结果将约束NaF系统的演化，并使之能够与其他转换断层系统进行比较。资金将允许私人投资机构初步参与土耳其的研究巡洋舰。广泛的影响：拟议的工作对了解土耳其的地震灾害具有直接影响，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来加强国际联系。警察督察将继续进行外展工作。数据管理包括在获取/分析后两年内将各种存储库中的数据存档。

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.
