Résumé
This study presents a geomorphologic review of the northern sector of the Anaga Massif in order to establish a relative sequence of geomorphic processes. The present-day relief shows a polygenic nature, combining fluvial erosion with other prior erosive processes. The analysis of slopes and watersheds suggests the existence of an active instability process during the Quaternary. However, the anomalies of the drainage system are related with the differential resistance which shows basic dykes against erosion. Some geomorphologic features suggest the occurrence of an old flank collapse affecting the slopes of Taganana village. This instability will be a stage of the retreatment of the slopes which occurs in a volcanic island along time, in both emerged and submerged flanks.
