Abstract The relationship between rift zones and flank
instability in ocean island volcanoes is often inferred but
rarely documented. Our field data, aerial image analysis,

Ar chronology from Anaga basaltic shield
volcano on Tenerife, Canary Islands, support a rift zone--
flank instability relationship. A single rift zone dominated
the early stage of the Anaga edifice (~64.5 Ma).
Destabilization of the northern sector led to partial sea-
ward collapse at about ~4.5 Ma, resulting in a giant
