New Zealand researchers have found potential warning signs before a volcanic eruption using artifical intelligence. They did this by studying recordings from GeoNet seismometers before 18 eruptions across six active volcanoes around the world, including Ruapehu, Tongariro, and the Whakaari White Island volcanoes. The pioneering research was spurred by the deadly Whakaari eruption. Karyn spoke to co-author of this research, University of Canterbury's Dr David Dempsy.
