Multiple-tremor detection result. a Two tremors are located as local maxima in the ACC distribution, occurring between 02:45 and 02:50 on November 16, 2010. The western tremor occurred at 02:48:25, with a hypocentral location of 33.919°N, 133.888°E, and 29.0 km depth. The eastern tremor occurred at 02:45:28, with a hypocentral location of 35.057°N, 137.240°E, and 30.8 km depth. b Normalized envelope waveforms, time-shifted from the western source. The horizontal axis represents time in this time window, and 0 s corresponds to 02:45. c Normalized envelope waveforms, time-shifted from the eastern source
