|Simplified geology of Teide. Thick gray dashed lines show the location of rift zones as proposed by Carracedo (1994). Orotava and Guimar formed as large pieces of the island were removed by landslides. The landslides are caused by the gravitational instability of the large island.|
Teide is a stratovolcano capped by the Las Canadas caldera. The caldera is 7-12 miles (12-20 km) in diameter and partial filled by Montana Blanca, Pico Viejo (which has a large explosion crater), and Pico de Teide. Pico de Teide and other vents of Teide have erupted several times since the island was settled in 1402. The most recent eruption was in 1909. It lasted only ten days, producing lava flows that caused some damage.

The Space Shuttle radar experiment called SIR-C/X-SAR, which flew in October 1994, collected this radar image of Piton del Teide using 5.6 cm (C-Band) and horizontally-transmitted, vertically-received (C-HV) measurements. Areas that are topographically rough or scarps that face the radar are bright in this image. The different numbers mark the locations of the other images presented here and, where given, the arrows show the direction that we are looking.
