Volcanoes with Natália Gauer Pasqualon - #25

In this episode I am joined by Doctor Natalia Gauer Pasqualon, a volcanologist at the University of Hawaii at Manoa. The focus of this episode is volcanology, which is the study of volcanoes and geochemical phenomena.We first discuss how Natalia decided to study geology for her undergraduate degree and how Natalia ended up finishing two PhDs in volcanology. Then we get into volcanology. Natalia defines what a Volcano is, the difference between lava and magma, hotspots, the different types of volcanoes, volcanic eruptions, underwater volcanoes, super volcanoes, the terabytes of data she has to work with and much more. I hope you enjoy!
