A new technique for the analysis of three-component seismic data from
a single station is presented. 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.
