Figure 7
Comparison of infrasonic waveforms obtained at station V.MYCR. Each infrasonic signal is plotted with the same time axis and is tagged with the local times, and the amplitude is normalized relative to the maximum amplitude of each infrasonic signal. The infrasonic pulse and their clear dilatational onsets are indicated by bold bars and arrows, respectively. Solid circles denote saturated waveforms due to the poor dynamic range of the instrument.
