In this episode, Janine and I banter about the volcanoes of South America. Then we get into Plinian eruptions, how calderas are formed, what happens during a massive eruption and ignimbrites (one of Erik's favorite volcanologic words). This is Part 3 of a special mini-series on Volcanology Basics for anyone to use during the Great Hiatus.Episode Page (with slides and other info)Support the show
