In the laterally heterogeneous and anisotropic earth the particle
motions of seismic waves are three-dimensionally polarized. This
paper presents a method for determining a local wave coordinate system
using the zeros of some component operators in rotated systems. It
is applicable to broad-band composite waveforms and offers higher
precision and resolution for the determination of azimuth and incidence
angle than the usual least-squares techniques. The algorithms have
been implemented in an interactive program for processing three-component
digital recordings. In addition, the program allows the use of particle
motion diagrams and component products for the determination of wave
types, onset times, and pulse durations. Its performance is demonstrated
on regional and teleseismic events recorded at the European broad-band
stations GRF (Gräfenberg, West Germany), KHC (Kasperské
Hory, Czechoslovakia) and KSP (Ksiaz, Poland).
