云南GNSS基准站连续观测资料应用研究

Research on the Application of Continuous Observations Data Recorded by GNSS Reference Station in Yunnan

对云南28个GNSS基准站所记录的数据进行跟踪处理,得到了GNSS基准站点之间基线和点位移变化的时间序列,通过对时间序列的分析,获得了云南省内部分活动断层的现今活动特征以及在大震前块体的活动情况,为利用GNSS数据探索地震预测预报进行了初步尝试。

Through track processing of data recorded by 28 GNSS Reference Stations, we obtained time series varia- tion of baseline length and point displacement. Then analyzing these time-series results, we obtained the recent activity characteristics of some active faults and the block movements before the major earthquakes in Yunnan. The GNSS data is applied for earthquake prediction preliminarily.
