Example waveforms of seismo-acoustic signals. These waveforms have a a short time delay and b a long time delay of the arrivals. Dashed lines are the arrival times read manually. The solid line shows the time 1.12 s before the infrasound arrival. The maximum value of the time delay that can be reproduced by our model is 1.12 s. However, the time delay of example b seems to be longer than 1.12 s. Perhaps the initial phase of the infrasound signal was not excited well, causing the time delay to appear to be extended
