U.S.-Chile Cooperative Research in Crustal Deformation, Part II

该奖项支持在地壳变形方面的合作研究。这项工作将由加州大学圣克鲁兹分校的史蒂文·n·沃德和圣地亚哥智利大学的塞尔吉奥·巴里恩托斯共同完成。他们建议研究1960年智利南部地震的同震位移场以及该事件和1985年智利中部地震的震后地壳变形。大地测量高程变化、三角测量和潮汐计观测将用于详细指示同震滑动和震间蠕变的位置和强度。智利有重要的大地测量和地震资料。Barrientos的美国培训和智利联系将促进这些数据集的利用和新测量数据的收集。这是美国和智利科学家之间互利科学合作的绝佳机会。智利人将能够使用美国科学家的先进技术来处理这些数据，而美国科学家将了解地震周期中应力积累的细节。该奖项将有助于维持有益和富有成效的国际科学关系，从而进一步实现“发展中国家科学”项目的目标。

This award supports cooperative research in earth crust deformation. The work will be performed by Steven N. Ward of the University of California, Santa Cruz and Sergio Barrientos of the University of Chile in Santiago. They propose to study the coseismic displacement field of the 1960 earthquake in southern Chile and the postseismic crustal deformation of that event and the 1985 earthquake in Central Chile. Geodetic elevation changes, triangulation measurements and tide gauge observations will be used to indicate the location and intensity of coseismic slip and interseismic creep in great detail. There is important geodetic and seismic data available for Chile. The U.S. training and Chilean contacts of Barrientos will facilitate the utilization of these datasets and the collection of new measurements. This is an excellent opportunity for mutually beneficial scientific cooperation between U.S. and Chilean scientists. The Chileans will be able to use the advanced techniques of the U.S. scientists to handle this data and the U.S. scientists will learn the details of stress accumulation during the earthquake cycle. This award will help maintain a useful and productive international scientific relationship and thus further the goals of the Science in Developing Countries program.
