Exceptional recurrence of flank destabilizations in the recent activity of the Colima volcanic complex, Mexico; Recurrence exceptionnelle de destabilisations de flanc dans l`activite recente du complexe volcanique du Colima, Mexique

Abstract

This short paper reports on new {sup 14}C datings of debris flow units from the Nevado de Colima and Fuego de Colima volcanoes in Mexico. These new datings in connection with a detailed stratigraphic study in the deep canyons around the volcanoes has revealed an exceptional recurrence of flank destabilizations of the Fuego de Colima during the last 45000 years. The cumulated volume of debris in the whole Colima massif is estimated to 60-100 km{sup 3}. The correlation between Landsat satellite pictures and the distribution and age of the debris flows shows that both volcanoes are made of several post-destabilization remaining structures, and that both volcanoes were active and simultaneously collapsed 18500 years ago. The numerous fluvial-lacustrine sequences intercalated between the successive flows indicate that the debris flow were partially sedimented under water and could have led to catastrophic tsunamis towards the Pacific coast. Implications of this work are important because a population of more than 200000 inhabitants is living in a zone covered by several debris flows. (J.S.).
