Geothermal exploration of the Martinique Island (Lesser Antilles) focused, at first (1960-1980 years), on the Lamentin lowlands and on the Southern flank of the Mount Pelée volcano. In 2003, a new step was done with the identification of two areas of interest: the SW side of Mount Pelée dome and the surroundings of the Petite Anse - Diamant hot springs (Sanjuan et al., 2003). The 2012-2013 additional and combined - geological, hydrogeological, geochemical, geophysical - surface exploration results in a new insight of the Martinique geothermal systems, including Mount Pelée volcano, Petite Anse - Diamant area, Pitons du Carbet domes and Lamentin lowlands. High temperature geothermal systems are supposed to be active at both the former sites whereas only signs of medium to low temperature were detected at the Lamentin and Pitons du Carbet areas.
