Cross-correlation analyses of the data in Fig. 1 at a 1–3.5 Hz, b 3.5–7 Hz, c 7–12 Hz, and d 12–18 Hz. In each panel, the top and middle frames show the band-passed infrasonic data (\(d_p\)) and seismic data (\(d_v\)), respectively. The bottom frame shows the cross-correlation coefficient between the seismic data, \(d_v\), and infrasonic data, \(d_p\), with the vertical axis representing the time delay, \(\tau \), of \(d_v\) to \(d_p\). The horizontal dashed line indicates \(\tau =0\)
