Summary The force system at the source of the colossal Chile earthquake of May 1960 was derived from spectral amplitudes of free oscillations and Mantle surface waves recorded at Pasadena and Isabella California, Kyoto Japan and Ogdensburg, New Jersey. Although the data are sparse and the azimuthal coverage is partial, there is ample evidence to indicate a unique solution which is a dip‐slip motion on a fault dipping 45° to the east with the oceanside downthrown.
