Shear‐wave arrivals in vertical seismic profiling recordings made with Vibroseis can be more accurately determined by wavelet processing and spectrum whitening. This method aids discrimination of shear‐wave arrivals against P‐wave disturbances. The data, thus improved, can be used to determine the main axis of shear‐wave polarization for each sounding depth in order to maximize shear‐wave amplitude by properly adding the two horizontal component signals vectorially.
