when was the last time the volcano erupted in tenerife
Teide 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,[a] and is described by UNESCO and NASA as Earth's third-tallest volcanic structure.[5][6][b] 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[7] 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.
Mount Vesuvius The volcano is closely monitored by the Osservatorio Vesuvio in Naples with extensive networks of seismic and gravimetric stations, a combination of a GPS-based geodetic array and satellite-based synthetic aperture radar to measure ground movement and by local surveys and chemical analyses of gases emitted from fumaroles. All of this is intended to track magma rising underneath the volcano. No magma has been detected within 10Â km of the surface, and so the volcano is classified by the Observatory as at a Basic or Green Level.[66]
