Abstract The co-seismic displacements, strains, geoid and gravity changes caused by the Wenchuan Ms8.0 earthquake in Three Gorges and Beijing areas were calculated respectively. Compared with that caused by the Surmatra earthquake in 2004, in Three Gorges area the coseismic displacements are about a half but the strains are about 2-3 times. In Beijing area the deformations are smaller than those of the 2004 Sumatra earthquake by 1-2 orders,totally. Thus, the possibility of strong induced earthquake is low in Three Gorges area, and is zero in Beijing area.
Key words ：
the Wenchuan earthquake
dislocation theory
displacement
strain
gravity change
