DISCRIMINATION BETWEEN POST??SEISMIC EFFECT AND ??
EARTHQUAKE PRECURSOR OF VERTICAL DEFORMATION |

| Abstract: | Discrimination between post-seismic effect and earthquake precursor of vertical deformation after large earthquake was analyzed with the regional leveling and fault-crossing leveling data before and after ??Ms 8.1 earthquake in Qinghai-Xinjiang area and Wenchuan ??Ms8.0 earthquake in the northeast margin of Qinghai-Tibet.The results show that: Post-seismic effect was reflected by counter??inheritance motion of mountain decreased and basin uplift??it indicates that the tectonic stress field “weak compressing” or “relaxation” before big earthquake??And earthquake precursor of vertical deformation was reflected by inheritance motion of ascending and descending differently??it indicates an intensive trend of tectonic stress field before big earthquake. |
