Polarization analysis of single station multicomponent seismic data has been performed with success by several researchers (Montalbetti and Kanasewich, 1970; Vidale, 1986; Flinn, 1965; Esmersoy, 1984; Magotra et al., 1987). The technique has two major objectives: (1) to devise filters to distinguish between events with different modes of vibration (e.g., P- and S-waves versus Rayleigh waves) and (2) to provide a means of estimating the direction of particle motion for use in seismic direction finding.
