Teide volcano is the highest peak in the Atlantic Ocean and has a height of 7500 m above the ocean floor. The volcano has a history of large destructive eruption which affect populated areas. The volcano was observed in eruption by Columbus in 1492. Teide National Park was declared a UNESCO World Heritage site in June 2007.

2005 Volcanic activity
Volcanic unrest occurred at the volcano in January 2005. Carbon dioxide emissions rose from 75 to 354 tons per day, and hydrogen sulfide emissions rose from 35 to 152 tons per day. Seismic activity remained elevated under the volcano. Fumaroles increased in pressure, and emitted sounds. There was no significant ground deformation recorded.

2004 Earthquakes
Seismic activity increased at the volcano during April and May 2004. Over 200 earthquakes from magnitude 1 to 3 were recorded, with three being felt by residents. Most earthquake epicenters were centred around the NW rift zone of Tenerife and in the strait between Gran Canaria and Tenerife. The earthquake crisis was probably related to dike emplacement at 3-4 km depth.
