AB Geologic evidence on Tenerife, Canary Islands, indicates six successive north-directeddebris avalanche events, including: the Anaga and Teno (ca. 6 Ma) events that affected the oldbasaltic series, and the Tigaiga (>2.3 Ma), Roques de García (possibly 0.6–0.7 Ma), Orotava(ca. 0.6 Ma), and Icod (<0.15 Ma) avalanche events that affected the Cañadas and Dorsal volcanicedifices. The approximate total volume (>1000 km3) inferred for these events can accountfor the volume of previous estimates of offshore volcanic debris. These repeated flank failurescan also account for the present morphology of Las Cañadas caldera wall, which partly boundsa multiepisodic lateral-collapse structure 25 km wide.
