Histograms of observed differences in seismo-acoustic signal arrival times. a Distribution of time differences between the arrival of the VLP seismic signal at UMA and the arrival of the low-frequency infrasound signal at ACM, ΔtsL–iL. b Distribution of time differences between the eruption earthquake at KAF and the high-frequency infrasound signal at ACM, ΔtsH–iH. c Distribution of time differences between low- and high-frequency infrasound signals at ACM, ΔtiL–iH. The total number of events (N) and the mean and mode values are shown in the upper right in each diagram
