利用SG-C053超导重力仪检测智利8.8级地震激发的地球自由震荡
DETECTION OF EARTH'S FREE OSCILATION EXCITED BY CHILE Ms8.8 EARTHQUAKE BY USING SG-C053 SUPER CONDUCTING GRAVIMETER
摘要
Abstract
Using the gravity data recorded by the SG-C053 super conducting gravimeter during the Ms8.8 Chil0e 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.关键词
