In the podcast, Michael Manga explains how the most powerful eruptions, such as the 2022 Hunga Tonga eruption, occur when hot magma comes into contact with water and suddenly generates vast quantities of steam. Water dissolved in magma as it rises to the surface and depressurizes can also drive destructive volcanic eruptions. Manga also talks about water-driven volcanism on Mars and on the icy moons of Jupiter and Saturn. Manga is a Professor in the Earth and Planetary Science department of the University of California, Berkeley. ## Actions - request_transcript: `POST https://stenobird.com/v1/public/podcasts/geology-bites-159592/episodes/michael-manga-on-wet-eruptions/transcription-requests` — Idempotently request low-priority transcript generation for this episode. - read_markdown: `GET https://stenobird.com/podcast/geology-bites-159592/michael-manga-on-wet-eruptions.md` — Read the agent-friendly Markdown representation of this episode resource.
