From base to peak which is the highest volcano in the world outside of the Hawaiian Islands?

Mount Teide is a volcano on Tenerife in the Canary Islands, Spain. Its summit at 3,718 m (12,198 ft)) is the highest point in Spain and the highest point above sea level in the islands of the Atlantic.

If measured from the ocean floor, it is at 7,500 m (24,600 ft) the highest volcano in the world base-to-peak outside of the Hawaiian Islands, and is described by United Nations Educational, Scientific and Cultural Organization (UNESCO) and National Aeronautics and Space Administration (NASA) as Earth's third-tallest volcanic structure.

Teide's elevation makes Tenerife the tenth highest island in the world. Teide is an active volcano: its most recent eruption occurred in 1909 from the El Chinyero vent on the northwestern Santiago rift. The United Nations Committee for Disaster Mitigation designated Teide a Decade Volcano because of its history of destructive eruptions and its proximity to several large towns, of which the closest are Garachico, Icod de los Vinos and Puerto de la Cruz. Teide, Pico Viejo and Montaña Blanca form the Central Volcanic Complex of Tenerife.
