beskrivelse:

This is a very schematic diagram of the formation of the island of Tenerife and evolution of the current Teide volcano. In step one the island began as three separate shield volcanoes - Anaga to the NE, Teno to the NW and Roque del Conde to the south. Step Two: After a period of erosion of the older massifs a new period of volcanic activity saw the creation of the large Las Canadas volcano. Step Three: The islands current shape begins to become apparent as Las Canadas grew. Step Four: The Las Canadas edifice collapsed to form the Las Canadas Caldera into which Step Five: The current Teide/Vierjo Central complex has grown within this collapsed Las Canadas Caldera (more detailed/smaller of two versions).
