东日本大地震前后陆态网络基准站形变研究

CMONOC Fiducial Station Deformation Before and Afterthe Tohoku-Oki Earthquake

  • 摘要: 计算了东日本大地震前后各1a的“陆态网络”基准站GPS观测数据,得到了基准站的时间序列及其运动速度,讨论了较长时间尺度上东日本地震对“陆态网络”基准站造成的影响?峁砻鳎胝鹎跋啾龋夜钡厍嗾鹬薪辖幕颊镜脑硕俣扔屑铀偾阆?运动方向偏向震中位置,华东地区、华南地区基准站的运动速度和方向在震前震后基本一致。

     

    Abstract: By calculating GPS observation data from some fiducial stations in CMONOC each year be-fore and after the Tohoku-Oki earthquake,time series and velocity data from these fiducial stationsobtained.On this basis,this paper discusses the impact of the Tohoku-Oki earthquake on the fiducialstations on a longer time scale.This research shows that as compared to the velocity before the earth-quake,the fiducial stations in northeast China near the epicenter had a accelerating trend,and themovement direction tended towards the epicenter,while the movement velocity and direction of the fi-
