| Abstract: | The measurement results of T-1 absolute gravimeter showed abnormal values after the Japan Ms9.0 earthquake occurred in March 11th 2011. The deviation caused by the powerful aftershocks of the earthquake reached at as large as 656×10-8 ms-2. The disturbed vibration isolation is the main reason of the abnormal values，according to the analysis for dropping chamber，interferometer and vibration isolation. |
| Keywords: | absolute gravimeter co-seismic response Japan Ms9 0 earthquake vibration isolation system error |
