Vulkane in Kanarische Inseln (7)
The Canary Islands are a chain of volcanic ocean islands located off North Africa's west coast (Western Sahara and Morocco). The islands are the type example of oceanic hot spot volcanoes above a slow-moving, thick oceanic plate.
The age of volcanism decreases from east to west, as the Atlantic plate slowly moves ENE above the Canarian Hot Spot. From the oldest to the youngest, the islands are Lanzarote, Fuerteventura, Gran Canaria, Tenerife, La Gomera, La Palma and El Hierro.
Lanzarote and Fuerteventura, the oldest islands, are in their erosional stage and recent volcanic activity is explained by a secondary mantle convection at the continental margin.
Gran Canaria and Tenerife are in the post shield phase with rejuvenated volcanism. Rejuvenated volcanism has not yet started at La Gomera, which is in the erosional stage after the shield building phase has ended, and might skip this stage, as no volcanism has occurred for 2-3 million years and volcanic pathways have probably sealed.
La Palma and El Hierro, the youngest of the island chain, are still above the hot spot and in their shield building phase.

The triangular island of El Hierro is the SW-most and least studied of the Canary Islands.
Following intense earthquake swarms since July 2011, a new submarine eruption started in Oct 2011 at a vent ca. 1 km south of La Restinga off the southern tip of the island. The erupt... [mehr
Pleistocene and Holocene cinder cones and lava flows cover large portions of elongated Fuerteventura Island at the SE end of the Canary Islands. [mehr
The largely Miocene-to-Pliocene island of Gran Canaria in the middle of the Canary archipelago has been strongly eroded into steep-walled radial gorges called barrancos. [mehr
La Gomera is one of the most beautiful of the volcanic Canarians. It is a heavily eroded ocean island shield volcano. Although it is the 3rd youngest of the Canarian island, it is already extinct. It stopped erupting about 3 million years ago. [mehr

The 47-km-long wedge-shaped island of La Palma, the NW-most of the Canary Islands, is composed of two large volcanic centers. [mehr
The 60-km-long island of Lanzarote at the NE end of the Canary Islands contains the largest concentration of youthful volcanism in the Canaries. [mehr
The large triangular island of Tenerife is composed of a complex of overlapping Miocene-to-Quaternary stratovolcanoes that have remained active into historical time. [mehr
