Where are the almost 100 volcanoes that Spain has?


Spain has two volcanic areas considered active -those where eruptions have occurred in the last 10,000 years-, which are the Canary Islands and the region of La Garrotxa, in Girona, but there are also inactive volcanoes in Cabo de Gata (Almería), Cofrentes (Valencia), the Columbretes Islands (Castellón) and Campo de Calatrava (Ciudad Real). Altogether, they are a almost 100 volcanoes that Spain has.

The Canary Islands are currently the only area of high volcanic risk in Spain and the islands of La Palma, Tenerife and El Hierro the most active, according to the National Geographic Institute (IGN). All the volcanic eruptions recorded in recent centuries in Spain have occurred in this archipelago, seven of them on the island of La Palma.

The other zone considered active, although without having recorded any eruption for thousands of years, is the Garrotxa region, in Gironawhere the Natural Park of the Volcanic Zone of the same name is located, reports the Efe agency.

In the area there 40 volcanic cones, including the Santa Margarida volcano, in the municipality of Santa Pau, whose last eruption took place 11,000 years ago; the Croscat, of the Strombolian type, the youngest and largest in the area and also the largest in the Iberian Peninsula.

Furthermore, in the middle of Olot city is the Montsacopa, which with a crater of 120 meters in diameter is aligned between the Mopntolivet and Garrinada volcanoes.

Volcanism is documented between 15 and 16 million years ago in Cabo de Gata (Almeria), when magmatic activity began in the Alboran Sea. There is no active sign either, but it is the most complex volcanic complex in the Iberian Peninsula, as it has submarine and surface volcanoes, such as lava domes, such as Fraile and Fraile Chico, and volcanic calderas, such as the Caldera del Plomo or Majada Redonda.

Also asleep is the Valencian volcano of Cofrentes, located on the Agrás hillabout 500 meters above sea level and close to the nuclear power plant of the same name.

Like the previous one, the volcano of las Columbretes Islands, off the coast of Castellónin which according to some studies there was activity a few 300,000 years.

Likewise, in Castilla-La Mancha, specifically in Campos de Calatrava, in Ciudad Reala volcanic area of ​​about 5,000 square kilometers is located, where some 300 volcanic manifestations have been documented, among them the Cerro Gordo volcano, located between Granátula and Valenzuela, or the Columba volcano, which with 5,000 years of life is located between Calzada and Granatula.

Besides, in Valverde, also in Ciudad Realis the Posadilla or Fuentillejos volcano, in whose crater a lagoon was created by the contact of the lava in contact with an important layer of underground water.

In Spain, as explained by the IGN, it is necessary to differentiate, on the one hand, the volcanism that is located in the peninsular area and in some of its nearby islands and, on the other, that found in the Canary Islands.

While the origin of the former is related to the collision between the African and Eurasian plates, the Canary Islands is in contact with the formation of a hot spot inside an oceanic plate, located in contact with the African continent.

40 volcanoes in the Canary Islands

In the Canary Islands there are four dozen volcanoes. The most famous of all is the Mount Teidein Tenerife, the highest peak in Spain (3,715 meters) and the third highest volcano in the world. The largest eruption of which there is news in Spanish territory occurred in the Timanfaya volcano, in Lanzarote, and lasted 2,055 days, between 1730 and 1736.

Until the last one that occurred in Cumbre Vieja, the last eruption had been that of the submarine volcano Tagoro, off the coast of El Hierro, in October 2011. 50 years ago, in 1971, the previous terrestrial eruption was recorded, in the Teneguía volcano , also on La Palma.
