Relationship between the infrasonic and seismic RMS amplitudes as measured at OWD station. The seismic RMS amplitude was estimated using 1-s three-component velocity waveforms from immediately before the infrasonic onsets that occurred from 04:05 to 05:30 on July 1. The dashed horizontal line indicates the seismic RMS amplitude before the eruptive activity on 04:05:23 on July 1 (time period indicated by the blue line in Fig. 11a)
