Shot fact coming from the plane to Tenerife, with impressive image of Teide volcano.

Teide (Mount Teide or Pico de Teide) is a volcano and mountain on Tenerife, Canary Islands (28.27 N, 16.6 ]W). At 3717 m above sea level and approximately 7000 m above the adjacent sea bed, it is the highest mountain in Spain, and the third largest volcano on Earth.
It is currently dormant, having last erupted in 1909 from the subsidiary vent of Chinyero on the west slope of Teide. Other significant eruptions occurred in 1704–1706 and 1798. The summit has a number of small active fumaroles emitting hot sulfur dioxide and other gases.
Further eruptions are considered likely in the future, including a risk of highly dangerous pyroclastic flows similar to those on Mount Pelée and Mount Vesuvius. Teide is a modern name given by the Spanish, the name given to the volcano was Echeyde by the native Guanches, prior to the Spanish colonization. Echeyde, per the Guanches legends, meant some sort of powerful figure leaving into the volcano that could turn into hell.

In prehistoric times, about 150,000 years B.P., a much larger explosive eruption occurred, probably of Volcanic Explosivity Index 7, creating Las Cañadas, a large caldera at just over 2000 m altitude, 15 km across east-west and 10 km north-south.
On the south side, the internal crater walls rise as almost sheer cliffs from 2100 m to 2715 m at Guajara. The 3717 m summit of Teide itself, and its subsidiary vent Pico Viejo (3134 m), both in the northern half of the caldera, derive from eruptions subsequent to this prehistoric explosion.
