Abstract
Following the way in a previous paper, Fourier analysis of gravimeter records of the Chilean earthquake of May 22 in 1960 obtained in Kyoto is extended to larger wave numbers. The period range covered by the present study is from 66.4min. to 8.4min. Spectral peaks corresponding to the earth's spheroidal oscillations of n=2 to 12 are seen in the results shown in Fig. 1. Observed oscillation periods seem to be a little longer than those predicted by Pekeris and others for the Gutenberg model. This may be due to a low velocity zone being nearer to the earth surface under Japan.
