Abstract

The Miocene volcanic Edifice of Jandía is a large central volcano formed through different cycles of volcanic construction and destruc- tion by large gravitational landslides. In this sense, at least three large gravitational landslides affected the Miocene volcanic Edifice of Jan- día: the Morro de Mungía landslide, which destroyed the southern flank of the Upper East Jandía Edifice; La Degollada de Cofete lands- lide, that subsequently affected the entire western sector of this same Edifice and on whose rocky avalanche deposits the Western Upper Jandía Edifice grew; and finally, a last landslide which afterwards affected the northern flank of the entire Jandía Edifice, giving rise to the formation of the current Cofete arch. It is also possible that the Lower Jandía Edifice underwent an early gravitational landslide of its northern flank, which resulted in the formation of a large depression open to the North, on top of which the Middle Jandía Edifice and the Upper East Jandía Edifice grew
