Magmas near the critical degassing pressure drive volcanic unrest towards a critical state

Magmas may migrate through hydrothermal fluids, but magma-hydrothermal interactions are poorly understood. Here, Chiodini et al. use physical and volatile models showing that at a critical degassing pressure the release of magmatic gases can heat hydrothermal fluids triggering deformation leading to...

Sumario:Magmas may migrate through hydrothermal fluids, but magma-hydrothermal interactions are poorly understood. Here, Chiodini et al. use physical and volatile models showing that at a critical degassing pressure the release of magmatic gases can heat hydrothermal fluids triggering deformation leading to eruption.
