Abstract:

A method is proposed for whitening the spectra of teleseismic P waves to aid in the determination of event depths. The method uses a network of common recording stations, all of which must have recorded signals from a suite of closely-spaced events, e.g., a set of underground explosions. Individual spectra are whitened by removing a path-recording site response determined by averaging spectra from the suite of events as recorded at a single station. The whitened spectra from a single event are then summed over the recording network to yield a whitened source spectra. The whitening process enhances spectra components in the band 2 to 5 Hz.
