Abstrakt: The Canary Islands geoid anomaly shows only a short-wavelength high associated with island topography. The predicted anomaly best matches the observed geoid when we assume that the lithosphere is a very stiff plate. We find no evidence for shallow reheating or a mantle plume, since there is no evidence of a midplate swell and the corresponding elastic thickness is appropriate for the age of the seafloor on which the island group rests.
