Kilauea is one of the world's most studied volcanoes, but its deep plumbing still holds mysteries. In this episode, we dive into a "bottoms-up" view of Hawaii’s magmatic system with Gaetano Ferrante, exploring how pressure changes in the deep mantle conduit propagate to the surface.

While volcanologists often focus on shallow, top-down triggers like summit collapses or CO2 degassing, Gaetano’s recent research suggests that the deep mantle pathway—stretching nearly 100 km down—plays a much more active role in regulating magma supply than previously thought. We break down the mechanics of mantle plumes, the transition from magmastatic to lithostatic pressure, and why the "elastic" response of volcanic pipes might explain Kilauea’s stable behavior following the massive 2018 eruption.
