Sumatra-Adaman大地震同震和震后形变的GRACE卫星检测

Detection of Co-seismic and Post-seismic Deformation Caused by the Sumatra-Andaman Earthquake Using GRACE

  • 摘要: 利用CSR公布的RL-04版GRACE卫星月重力场模型计算了9.1级Sumatra-Adaman大地震的同震和震后形变效应。数值结果表明,GRACE能够监测到的同震和震后形变量为-20~10cm的等效水高,为大地震同震和震后形变监测提供了一种独特、有效的方法。

     

    Abstract: The co-seismic and post-seismic deformation caused by Sumatra-Adaman earthquake are computed by using RL04 GSM monthly gravity model of GRACE published by CSR.The analysis and comparison of numerical results show that co-seismic and post-seismic deformation information about-20-10 cm equivalent water thickness from large earthquake can be detected by GRACE satellite gravity surveying.
