Dynamics of Piton de la Fournaise

Piton des Neiges is well known for its thermal springs exploited since the XIXth century. Thermal springs are surface evidence for an active hydrothermal system, which ask the question about the geothermal potential of  this dormant volcano.

Our research focuses on determining the nature and the location of the heat source responsible for hydrothermal activity, as well as the maximum temperature reached by the hydrothermal fluids. The goal of this research is to encourage industrial investment for the development of geothermal energy at La Réunion as a more sustainable energy source than fossile fuel.
