U.S.-Indonesia Cooperative Research: Geodetic investigation of oblique plate convergence in Sumatra

这项提案要求提供资金，允许耶胡达博克博士，斯克里普斯 加州大学圣地亚哥分校海洋学研究所， 印尼国家协调中心的Jacub Rais博士 （BAKOSURTANAL），为期24个月，a 研究印度尼西亚群岛的构造，使用 全球定位系统（GPS）的测量。 他们将 研究斜向板块会聚变形 苏门答腊岛。 具体而言，他们将研究 斜滑与正俯冲和剪切的解耦 在平行于会聚边缘的断层上滑动， 苏美尔断裂西南和东北方向的变形 区 本项目的远期目标是扩展GPS 整个印度尼西亚群岛的测量数据， 专注于特定的构造问题，如 弧-陆滑动的分布和速率 在印度尼西亚东部的班达弧发生碰撞。 在印度尼西亚地区，许多构造过程导致 造山运动，大陆增生， 大陆，蛇绿岩位移，俯冲发展 带，弧极性反转，盆地闭合等，现在 活跃 该项目将为美国科学家提供一个独特的 有机会观察这些现象。 因为印尼位于 高地震和火山活动区，监测 地壳变形具有潜在的人道主义和经济 价值也是。 美国和印度尼西亚的合作者高度重视 有成功研究记录的受人尊敬的科学家， 这个项目的领域。 本项目将允许 合作者联合收割机结合他们的才能和利益， 效益 该项目与《公约》的目标有关， 发展中国家科学计划，旨在增加 美国科学家和工程师之间的合作水平 与发展中国家的对应方通过 科学信息、思想、技能和技术的交流 并通过在互利问题上的合作。 初级 对该项目的支持由NSF资助号EAR 8817067提供， 印尼政府和世界银行。

This proposal requests funds to permit Dr. Yehuda Bock, Scripps Institution of Oceanography, University of California, San Diego, to pursue with Dr. Jacub Rais, Indonesian National Coordination Agency for Surveys and Mapping (BAKOSURTANAL), for 24 months, a study of the tectonics of the Indonesian archipelago, using measurements of the Global Positioning System (GPS). They will study deformation associated with oblique plate convergence in Sumatra. Specifically, they will examine the mechanism of decoupling of the oblique slip into normal subduction and shear slip on faults parallel to the convergent margin by measuring the deformation both southwest and northeast of the Sumatran fault zone. The long-range goal of this project is extend GPS measurements across the entire Indonesian archipelago, concentrating on specific tectonic problems such as the distribution and rates of slip associated with arc-continent collision in the Banda arc in eastern Indonesia. In the Indonesian region, many tectonic processes that result in mountain building, continental accretion, destruction of continents, displacement of ophiolites, development of subduction zones, arc polarity reversal, basin closure, etc. are now active. This project will provide U.S. scientists a unique opportunity to observe such phenomena. Because Indonesia lies in a zone of high seismicity and volcanic activity, monitoring of crustal deformations has potential humanitarian and economic value as well. The U.S. and Indonesian collaborators are highly respected scientists who have records of successful research in the field of this project. The present project will allow the collaborators to combine their talents and interests for mutual benefit. This project is relevant to the objectives of the Science in Developing Countries Program which seeks to increase the level of cooperation between U.S. scientists and engineers and their counterparts in developing countries through the exchange of scientific information, ideas, skills, and techniques and through collaboration on problems of mutual benefit. Primary support for this project is provided by NSF Grant No. EAR8817067, the Indonesian government, and the World Bank.
