Far-field deformations caused by the 2004 Sumatra earthquake

2004 苏门答腊地震在四川云南区域引起的理论水平排水量根据一个球形的脱臼理论被计算了，地震差错 model.The 重新适合理论排水量与在 situ.On 的 GPS 观察基本上一致的表演这个基础，我们计算了co地震的排水量，紧张，包括中国大陆和附近，严肃的变化和整个地球的大地水准面由这地震引起了。

Theoretical horizontal displacements caused by the 2004 Sumatra earthquake in the Sichuan-Yunnan area have been calculated according to a spherical dislocation theory and an earthquake-fault model. The results show that the theoretical displacements are basically consistent with the GPS observations in situ. On this basis,we have calculated the co-seismic displacements, strains, changes of gravity and geoid of the whole Earth, including China mainland and vicinity, caused by this earthquake. Key wards：
