title: High-Resolution Spectroscopy of the Earth's Free Oscillations, Knowing the Earthquake Source Mechanism.
abstract: A new method for identification of normal modes of oscillation of the earth yielded unambiguous determinations of many overtones never before identified. This method consists of the superposition of spectra observed at many stations over the earth, after a correction for the phase determined from the known earthquake source mechanism.
