Through this planning visit, Prof. David Anastasio of Lehigh University and colleagues at the University of Pennsylvania will initiate cooperative research with Spanish partners to examine tectonically driven landscape evolution at the active African-Eurasian convergent plate boundary, an area of slow tectonic activity. The counterpart, Prof. Juan Soto, with the Department of Geodynamics at the University of Granada has established expertise in geologic and geophysical knowledge of the Betic Cordillera of southern Spain, where a workshop and exploratory fieldwork will take place. The U.S. team's strengths in structural geology, paleomagnetism, process geomorphology, geodesy and analytical techniques complement the Spanish partners' deep knowledge of the Beltic-Rif field geology and data. Together, their goal is to refine plans for a study of the key processes that underlie seismic hazards and coastal uplift characteristic of the Betic Cordillera, where regional crustal strains are poorly qualified but offer an example of synonvergent extension and continental growth associated with continental collision and subduction slab rollback. Results from this collaboration will improve our fundamental understanding of continental collision and tectonic processes as well as the geologic hazards associated with living on an active plate margin. This research activity fulfills the program objective of advancing basic knowledge by enabling experts in the United States and Europe to share research resources and plan beneficial projects in areas of strong mutual interest and competence. Broader impacts include early career international research experience for participating U.S. graduate students, development of a new international collaboration, and a better understanding of seismic hazards in a densely populated region. If successful, the project will contribute to our understanding of the linkage between surface process with subduction zone processes.

通过这次规划访问，利哈伊大学的David Anastasio教授和宾夕法尼亚大学的同事将启动与西班牙合作伙伴的合作研究，以检查活跃的非洲-欧亚会聚板块边界的构造驱动的地貌演变，这是一个构造活动缓慢的地区。Granada大学地球动力学系的对口人员Juan Soto教授在西班牙南部的Btic Cordillera建立了地质和地球物理知识方面的专门知识，将在那里举办讲习班和勘探性实地工作。美国团队在构造地质学、古地磁学、过程地貌学、大地测量学和分析技术方面的优势与西班牙合作伙伴对Beltic-Rif油田地质和数据的深入了解相辅相成。他们的共同目标是完善研究Btic Cordillera地震灾害和沿海隆起特征的关键过程的计划，Btic Cordillera的区域地壳应变质量较差，但提供了与大陆碰撞和俯冲板块回滚相关的同步伸展和大陆增长的例子。这次合作的结果将提高我们对大陆碰撞和构造过程以及与生活在活动板块边缘相关的地质灾害的基本理解。这项研究活动通过使美国和欧洲的专家能够共享研究资源，并在共同感兴趣和能力很强的领域计划有益的项目，实现了促进基础知识发展的计划目标。更广泛的影响包括为参与研究的美国研究生提供早期职业生涯国际研究经验，发展新的国际合作，以及更好地了解人口稠密地区的地震危险。如果成功，该项目将有助于我们理解地表过程与俯冲带过程之间的联系。
