Abstract
Mode 0S0 was excited by the Indonesian earthquake of 19 August 1977 and recorded at the South Pole and at UCLA. Phase estimates from 16 independent time lapse spectra were used to determine the frequency of this mode to high precision. The result is f (0S0) = 2.932851 cph with a standard deviation of 11 ppm.
