Le volcan Piton des Neiges (La Réunion) concentre de nombreux indices d’hydrothermalisme en surface, suggérant l’existence d’un potentiel géothermique exploitable. Les précédentes campagnes d’exploration, débutées dans les années 70, ont mis en évidence des gradients géothermiques prometteurs dans les forages d’exploration géothermiques du cirque de Salazie. Cependant, elles révèlent aussi la difficulté d’identifier les zones perméables au sein de ce volcan. Les failles de caldera pourraient présenter cette perméabilité nécessaire, or aucun consensus n’existe quant à l’existence, le nombre et l’extension des calderas du Piton des Neiges. La carte géologique actuelle ne suffit pas car elle est très peu contrainte dans la zone interne du volc...
