U.S. - Chile Cooperative Research in Crustal Deformation

该奖项支持美国和智利在地壳形变方面的合作研究，这项工作将由加州大学的史蒂文·N·沃德、圣克鲁斯大学和智利大学的塞尔吉奥·巴里延托斯完成。他们建议研究1960年智利南部地震的同震位移场，以及那次地震和1985年智利中部地震的震后形变。将使用大地高程变化、三角测量和验潮仪观测来详细指示同震滑动和地震间蠕变的位置和强度。智利有重要的大地测量和地震数据。巴里延托斯在美国的培训和在智利的联系将促进这些数据集的使用和收集新的测量数据。这是美国和智利科学家开展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，美国科学家将了解地震周期中应力积累的细节。这一适度的奖励将有助于维持一种有用的国际科学关系。

This award supports U.S. - Chile Cooperative Research in Crustal Deformation, work to be performed by Steven N. Ward of the U. of Cal., Santa Cruz and Sergio Barrientos of the U. of Chile. They propose to study the coseismic displacement field of the 1960 earthquake in southern Chile and the postseismic 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 modest award will help maintain a useful international scientific relationship.
