Teide
Mount Teide (Spanish: Pico del Teide, IPA: [ˈpiko ðel ˈteiðe], ""Teide Peak"") is a volcano on Tenerife in the Canary Islands. Its 3,718-metre (12,198 ft) summit is the highest point in Spain and the highest point above sea level in the islands of the Atlantic. At 7,500 m (24,600 ft) from its base on the ocean floor, it is the third highest volcano on a volcanic ocean island in the world after Mauna Kea, Mauna Loa and others in Hawaii. Its elevation makes Tenerife the tenth highest island in the world. It remains active: 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.The volcano and its surroundings comprise Teide National Park, which has an area of 18,900 hectares (47,000 acres) and was named a World Heritage Site by UNESCO on June 28, 2007. It is one of the most visited national parks in the world, with a total of 2.8 million visitors, according to the Instituto Canario de Estadística (ISTAC). In 2013 it was the ninth most visited national park in the world. The Teide is the most visited natural wonder of Spain.
