Guests: Mike Poland, scientist-in-charge of the Yellowstone Volcano Observatory; Yan Lavallée, chair of magmatic petrology and volcanology at LMU München and scientific and technical board member of the Krafla Magma Testbed; John Eichelberger, volcanologist at the University of Alaska Fairbanks and founding scientist of KMT
