| 摘 要： | 2010年4月14日青海玉树县发生了Ms7.1地震.本文利用差分干涉合成孔径雷达(D-InSAR)测量技术,通过对日本先进陆地观测卫星搭载的ALOS PALSAR获得的雷达数据进行处理,提取了此次地震的同震干涉形变场.结果表明,形变场分布特征与其发震断层甘孜-玉树断裂带的左旋走滑特征一致;最大视线向形变量为-61.4c...

| Abstract: | An MS7.1 earthquake happened on 14 April,2010 in Yushu County,Qinghai Province.This paper processed data from the ALOS/PALSAR satellite of Japan and analysed the coseismic deformation characteristics of the Yushu earthquake using the Differential Interferometric Synthetic Aperture Radar(D-InSAR) technology.The investigation indicates that the deformation characteristics of this earthquake are consistent with that of seismogenic fault.The maximum slant range displacement is about-61.4 cm,and the overall hori... |
