Fig. 5

Examples of raw seismic waveforms recorded under various conditions predicted using models 0, 1, and 2. The upper three figures show the observed waveforms from the top in east–west, north–south, and vertical directions, and the vertical axis shows the normalized amplitude. The lower three figures show the results of model 0, model 1, and model 2 from the top. The vertical axis is probability. The dotted lines represent the probability values of P-wave and S-wave, respectively. When the probability exceeds 0.6, it is indicated by a solid line and is considered to be detected as the respective phase. a One earthquake in the detection window, b two seismic events of almost the same amplitude in the detection window, c two events of very different amplitude in the detection window, d poor signal-to-noise ratio, e, f multiple earthquakes of very different amplitude in the detection window
