Canary Islands ocean in the middle of the islands of La Gomera, Tenerife and La Palma; where the laurisilva forests grow. The seven major islands, one minor island, and several small islets were originally volcanic islands, formed by the Canary hotspot. The Canary Islands is the only place in Spain where volcanic eruptions have been recorded during the Modern Era, with some volcanoes still active (El Hierro, 2011). Volcanic islands such as those in the Canary chain often have steep ocean cliffs caused by catastrophic debris avalanches and landslides. The Teide volcano on Tenerife is the highest mountain in Spain, and the
La Palma tsunami, so it would only be a megatsunami locally in the mid Atlantic. An underwater eruption that began in September 2011 south of the island of El Hierro, gave rise to more speculation about the possibility of a megatsunami. As each island in the archipelago is an independent edifice often several tens of kilometres away from the adjacent island it is geologically impossible that volcanic activity on one island will influence the other islands. El Hierro lies about 100 km south of La Palma, over 100 km south-west of Tenerife. La Gomera – extinct since about 4 million year BP,
