Depósitos de tsunami originados por un deslizamiento gravitacional masivo en Tenerife (islas Canarias)

Mega-landslides that have occurred in the flanks of the volcanic edifices of the Canary Islands caused giant waves (tsunamis) that deposited fossiliferous sediments in nearby coastal platforms. Deposits of this type are located along the northwest coast of Tenerife, the so-called Isla Baja. The stratigraphy, lithology, sedimentology and faunal content of these deposits suggests that they were originated by a tsunami produced by a mega-landslide – and an associated eruptive event – affecting the northern flank and the central zone of the island ca. 160 ka ago. The Caldera de Las Cañadas and a depression called Icod valley, today almost completely filled by younger lavas, were formed in this event, the last large flank collapse reported in Tenerife.
