Based upon the auto- and cross-correlations of the three orthogonal components within a short time window an assessment is made of whether these data are consistent with the arrival of a P-wave or a linearly polarized S-wave which has a vertical component of motion. In many cases the procedure can discriminate between a major P-phase and S-phases or later arriving P-phases from analysis of the coda after the first detected arrival. the method is computationally efficient, providing for P-wave detections including estimates of azimuth, apparent surface velocity, and (for teleseismic events) source location, in real time on a small personal computer.
