A team of researchers with the U.S. Geological Survey and the University of Alaska has found that they could estimate the size of bubbles that form from underwater volcanoes by listening to infrasound produced by bubble formation. In their paper published in the journal Nature Geoscience, the group describes their study of the infrasound that was produced by an undersea volcano eruption near an Aleutian island and what they learned from it.
