Infrasonic recordings of volcanic eruptions, when accelerated to bring the frequencies within the range of human hearing, reveal similarity to the noises made by jet engines, say the authors of a paper in Geophysical Research Letters. Such recordings could offer a new way of understanding what is going on in volcanic eruption columns, it says here.
