Infrasound Signals Aid in Forecasting Volcanic Eruptions
National Public Radio’s “Science Friday” featured a January 25 interview with Boise State University professor of geophysics Jeff rey Johnson. Dr. Johnson reported how scientists have long relied on seismic readings of micro-tremblors and earthquakes in predicting when a volcano might blow its top, but techniques involving “infrasound” are proving more reliable.
