Short summary

In this paper we characterise the flux and composition of the gas emissions from Turrialba Volcano. We show that the measured gas signature provides evidence that Turrialba Volcano has entered an open-vent configuration with magmatic gases being emitted. This suggests that the hydrothermal system at the summit is quickly drying up and that the system is moving from a hydrothermal to a magmatic end member with implications for short-term monitoring and possible evolution of the state of unrest.
