Mount Teide or, in Spanish, El Teide, is an active though dormant volcano which last erupted in 1909 from the El Chinyero vent on the Santiago (northwestern) rift and is located on Tenerife, Canary Islands. The volcano and its surroundings comprise the Teide National Park (Parque Nacional del Teide in Spanish). The park has an area of 18900 ha and was named a World Heritage Site by UNESCO on June 29, 2007.
At 3718 m above sea level, and approximately 7500 m above the floor of the Atlantic Ocean, El Teide is the highest mountain in Spain, highest point in the Atlantic Ocean and the 13th highest mountain in the European Union. The actual summit stands 3 metres (10 ft) higher than the triangulation station, and associated bench mark, which has an altitude of 3,715 m (12,188 ft). The island of Tenerife itself is the third largest volcanic ocean island on Earth by volume. El Teide is also the third highest volcano on a volcanic ocean island.
