【摘要】 在介绍GPS单历元定位方法的基础上,利用陕西GNSS连续站的高频数据,通过高精度数据处理软件GAMIT/GLOBK的运动学定位模块Track,计算得到2011年3月11日日本东海M9.0级地震以及2012年4月11日印尼苏门答腊M8.6级地震时连续运行观测站的水平同震变形。解算结果表明:测站的同震变形能够体现地震波的传播过程,并在地震波特性和地震类型判定方面具有一定帮助。更多还原

【Abstract】 Based on the introduction of the single epoch GPS positioning method,the high-rate GPS data of Shaanxi continues observation stations are calculated by TRACK,the kinematic module of the GPS data processing software GAMIT/GLOBK.The co-seismic deformation of continuous observation stations caused by Mar.11,2011,M9.0 Japan East-sea earthquake are obtained,besides another massive earthquake,Apr.11,2012,M8.6 Indonesia Sumatra earthquake,are obtained too.The results showed that the co-seismic deformation can make a description of the spread of the seismic wave;furthermore,there is important research significance at the judgment of earthquake focal mechanism and the characteristic of the seismic wave.更多还原
