Novel Segmentation Technique Applied To Phase Detection In Teleseismic And Regional Seismic Waveforms

A novel technique is presented for segmenting seismic waveforms. The method produces waveform segments which closely correspond to explosion and earthquake signal onsets as well as additional structure of interest. Noise spikes or glitches are also successfully isolated. The approach uses threshold parameters obtained from human segmentation judgment tests and requires only simple, time domain calculations.
