Volcanoes in the Western Mediterranean
The archipelago of the Columbretes Islands is located in the Western Mediterranean, just fifty kilometres away from the port of Castellón, in the province of the same name in the Valencian Community. It consists of 24 islets divided into four groups, each of which is named after its main islet. From north to south: Columbrete Grande (L’Illa Grossa in Valencian), Perrera (Ferrera), Horadada (Foradada) and El Bergantín (El Carallot). The emerged area occupies 19 hectares.
