Abstract Using the gravity data recorded by the SG-C053 super conducting gravimeter during the Ms8.8 Chile earthquake break out in 2010,1,27, we succeed in detecting the Earth’s free oscilation from 0S0 to 0S48. In addition ,we observed the spectra splitting of the 0S2,0S3 and
0S4. Compared with the PREM model, the observed period of 0S0-0S48 coincides with PREM model.
Key words ：
