Volcano Lightning

Dear friends, thank you for joining us on our Geo-Insider theme on natural hazards!!!     

      After discussing why studying volcanology is so important in our last interview, we decided to continue with exploring some very niche aspects of volcanology. To do so, we’ve invited Franziska Keller who is a Ph.D. student at the Institute for Geochemistry and Petrology, at ETH Zürich. The goals of her BSc and MSc were to identify the morphological and geochemical impact volcanic lightning has on volcanic ash and rocks, and her current work focuses on the understanding of long-term petrological cycles in silicic calderas of Japan applying different petrological and geochronological techniques.

     From our discussion, you will find out not only about volcanic lightning, but also about calderas, geosciences in general, and Franziska’s own awesome story in this field. Also, Franziska is editor and author of the European Geological Union (EGU GMPV blog).     

       Check out her awesome posts on caldera cycles: https://blogs.egu.eu/divisions/gmpv/2021/08/11/do-caldera-eruptions-occur-in-cycles-2/ Thanks to everyone for watching!
