Summary The NS and EW components of the horizontal pendulums records of the eigenvibrations of the Earth excited by the Chilean earthquake of 1960 May 22 have been analysed by using spectral and co‐spectral methods in order to obtain statistical parameters describing the polarization and the total energy associated with the individual modes. The analysis is carried out on five successive partly overlapping sections of the records, thus obtaining information on the evolution of the phenomenon.
