【摘要】 利用SG-C053超导重力仪的观测资料,研究了2010年2月27日智利Ms8.8地震引发的球形自由振荡0S0～0S48的所有基频振型,检测结果与PREM模型的理论值相比,二者基本相符。更多还原

【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-0S-0 to-0S-{48}.In addition,we observed the spectra splitting of the-0S-2,-0S-3 and-0S-4.Compared with the PREM model,the observed period of-0S-0——0S-{48} coincides with PREM model.更多还原
