I’ve spent my career visiting volcanoes—first drawn by their natural beauty, and then compelled to understand the structure, processes, and time that shape them.”— Dr. Tamie J. Jovanelly Overview With over 1,350 active volcanoes worldwide and up to 70 eruptions occurring annually, understanding the geological machinery beneath our feet is vital to interpreting Earth's past and future. In this episode, host Donald Wayne Murphy sits down with Dr. Tamie J. Jovanelly—distinguished geologist, GSA Fellow, two-time Fulbright Research Scholar, and host on The Weather Channel. Dr. Jovanelly breaks down complex planetary forces into accessible insights, discussing her book Volcanoes: What Everyone Needs to Know (Oxford University Press) and her fieldwork across Iceland's tectonic rifts. From the historic destruction of Mount Vesuvius to the colossal threat of the Yellowstone Supervolcano, discover how magma, plate tectonics, and climate intersect—and how volcanism behaves on worlds far beyond Earth. Key Takeaways from the Discussion Inside the Magma Chamber: How and where volcanoes form, the structural dynamics of eruptions, and how scientists deploy modern tools to predict activity.Iceland’s Tectonic Rift: What happens when an island is actively pulled apart by plate boundary motion, and how volcanic and glacial forces constantly rebuild the landscape.Eruptions & Human History: The profound influence of historical volcanic eruptions on global climate patterns, civilization shifts, and ecological rejuvenation.Extraterrestrial Volcanism: Exploring active volcanic processes on other planets and moons across our solar system.About Dr. Tamie J. Jovanelly Dr. Tamie J. Jovanelly is an award-winning geologist, science writer, and international researcher based in Atlanta, Georgia. A Fellow of the Geological Society of America (GSA) and a two-time Fulbright Scholar, she holds a Ph.D. from Kent State University and has spent over two decades researching global water quality, climate change, and volcanism. She is the author of Iceland: Tectonics, Volcanics, and Glacial Features (Wiley) and Volcanoes: What Everyone Needs to Know (Oxford University Press), creator of the "Lessons in Geology" series, and founder of Adventure Geology Tours.
