GEO Wednesday: Exploring volcanoes’ roots - a journey to Patagonia and ... Blindern’s basement!

Volcanoes have fascinated humans for millennia. However, the processes governing volcanic eruptions remain to a great extent poorly understood. The main reason is that the migration of magma from the deep Earth’s interior to the surface at active volcanoes, through the so-called volcano plumbing system, is out of reach for direct observations. To overcome this challenge, Olivier Galland has led field expeditions in northern Patagonia to study ancient volcanoes, the roots of which are exposed by erosion.
