Harnessing Remote Infrasound to Study Volcanic Eruptions
Data from the 2015 eruption of Chile’s Calbuco volcano suggest the international network built to monitor nuclear explosions may also be used to detect and characterize volcanic activity.
Are We Prepared for the Next Mega Eruption?
The frequency of eruptions with a Volcanic Explosivity Index of 7 is only one or two per thousand years but we cannot afford to be complacent.
