U.S.-China Cooperative Research: GPS Studies in Northern China

9602179沈从文该奖项旨在支持沈正康与加州大学洛杉矶分校的David Jackson和天津市国家地震局的李延兴在利用全球定位系统调查中国构造形变方面的合作。研究人员将分析中国GPS站点的现有数据，并在中国北部启动进一步的研究，该地区比中国西部地区更活跃的地区受到的关注更少。欧亚板块东部存在活动构造变形，主要是由于其与印度板块的碰撞以及沿其东缘与太平洋板块的相互作用。无论是在整个板块边缘还是沿着个别断层，都发生了多少变形，这在很大程度上是未知的。显然，该地区作为一个整体的地震活动水平非常高。因此，拟议的工作是了解该区域动态的重要组成部分。该项目有很好的潜力通过加州大学洛杉矶分校小组和SSB小组之间的合作，在构造活动区建立全球定位系统基线。这可能会导致未来在中国建立永久的全球定位系统站点，这将使在中国及其周围工作的所有研究人员受益。

9602179 Shen This award supports development of cooperation between Zheng- Kang Shen and David Jackson, UCLA, and Li Yanxing, State Seismological Bureau, Tianjin, on investigation of tectonic deformation in China using the Global Positioning System (GPS). The researchers will analyze existing data from Chinese GPS sites and initiate further studies in North China, an area that has received less attention than more active areas in the western areas of China. Active tectonic deformation has been recognized within the eastern Eurasia plate, mainly due to its collision with the Indian plate and its interaction with the Pacific plate along its eastern margin. How much deformation has been taking place either across the plate margins or along individual faults there is largely unknown. It is clear that the level of seismic activity in the region as a whole is very high. Thus the proposed work is an important component of understanding the dynamics of the region. The project has good potential to establish a GPS baseline in a tectonically active area through cooperation between the UCLA group and the SSB group. This could lead in the future to establishment of permanent GPS sites in China, which would benefit all researchers working in and around China.
