In this episode we interview seismologist and volcanologist Marino Protti Quesada, who is the director of the Volcanological and Seismological Observatory of Costa Rica. There, Protti has dedicated almost 40 years to research, focusing mainly on the study of plate tectonics and of subduction processes that generate large earthquakes.

With his fascinating explanations of the Earth's internal dynamics, Marino reminds us that we live on an active planet, whose cycles and temporalities vastly exceed our human history. Shifting between planetary and personal scales, this episode speaks of that which moves us and of the unfathomable mystery that drives the scientific endeavor.
