Resumen

The Columbretes Islands constitute a small archipelago, formed by numerous islets, remains of the emerged part of volcanoes. Two of these volcanoes have a basic composition: the Columbrete Gran-de volcano and the Navarrete volcano. Both are tuff-rings of about one kilometer in diameter, the first of which has been formed in at least three eruptive phases. The craters of the Columbrete Grande volcano are aligned with the Navarrete volcano, defining a direction of volcanic activity of basic composition, unique in the archipelago.
