Geometry of the observation for the Tonga volcanic eruption and the waveforms of the absolute pressure gauges (APGs). a Arrival times of the peaks of the meteotsunamis (label F in b) at each station of S-net. Yellow lines show the contour lines of the arrival times. Inset represents the location of the Hunga–Tonga volcano. Square indicates the island station N.S6N19. The white line connects the N.S6N19 with the Tonga volcano along the great circle. b APG waveform after removing the long-period components for (top) a station N.S6N19 and (bottom) all of the used stations. The red dashed lines represent the time window of 5000 s for searching the arrival times of the first peaks
