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

9602179沈郑康与加州大学洛杉矶分校的David Jackson、天津市国家地震局的李彦兴在利用全球定位系统（GPS）调查中国构造变形方面的合作发展。研究人员将分析来自中国GPS站点的现有数据，并在中国北方开展进一步的研究。与中国西部地区更为活跃的地区相比，华北地区受到的关注较少。在欧亚板块东部，由于与印度板块的碰撞以及与太平洋板块在其东部边缘的相互作用，欧亚板块发生了活跃的构造变形。在整个板块边缘或沿着单个断层发生了多少变形在很大程度上是未知的。很明显，整个地区的地震活动水平非常高。因此，拟议的工作是理解该地区动态的重要组成部分。通过UCLA组和SSB组的合作，该项目具有在构造活动区建立GPS基线的良好潜力。这可能导致未来在中国建立永久的GPS站点，这将使在中国及其周边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.
