| 英文摘要 | Sun and dong (2014) studied the co-seismic geo-center movement using dislocation theory for a spherical earth model. however, they incorrectly considered the maximum vertical co-seismic displacement as the rigid geo-center motion (i.e., they did not separate the rigid shift and elastic deformation). in this paper, we correct sun and dong (2014) by using a new approach. we now define the geo-center motion as a shift of the center of figure of the earth relative to the center of mass of the earth. furthermore, we derive new formulas to compute the co-seismic geo-center and inner core's center movements caused by huge earthquakes. the 2004 sumatra earthquake and the 2011 tohoku-oki earthquake changed the geo-center by 1-4 mm and about 2 mm, respectively, and caused the inner core's center to displace by about 0.05 mm and 0.025 mm, respectively.
