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。
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.
