Montaña de Guajara

Tenerife

Stratovulcano · Spain · 3715 m

Teide volcano, the highest point on the island of Tenerife, towers above the scarp of the massive Orotava landslide, which occurred about 600,000 years ago. The light-colored area on the eastern foot of the volcano (left) is covered by tephra deposits from the Plinian Montana Blanca eruption about 2,000 years ago. Teide was constructed within the 10 x 16 km wide Las Cañadas caldera on the SW side of Tenerife. The large triangular island is composed of a complex of overlapping stratovolcanoes that have remained active into historical time.

Sintesi geologica

The large triangular island of Tenerife is composed of a complex of overlapping Miocene-to-Quaternary stratovolcanoes. The NE-trending Cordillera Dorsal volcanic massif joins the Las Cañadas volcano on the SW side of the island with older volcanoes, creating the largest volcanic complex of the Canary Islands. The origin of the 10 x 17 km Las Cañadas caldera, partially filled by the Teide stratovolcano, has been variably considered to be due to collapse following multiple major explosive eruptions or as a result of a massive landslide (in a manner similar to the earlier formation of the massive La Orotava and Guimar valleys), or a combination of the two processes. The most recent stage of activity beginning in the late Pleistocene included the construction of the Pico Viejo and Teide edifices. Tenerife was perhaps observed in eruption by Christopher Columbus, and several flank vents on the Canary Island's most active volcano have been active during historical time.
