How many active volcanoes are there in the Canary Islands?
The Canary Islands in Spain were formed hundreds of thousands of years ago by volcanoes, and some are still active as shown this week.
The eruption which started Sunday shortly after 3 in the afternoon hasn’t reached its climax yet and could continue for weeks or even a couple of months. The longest in Spanish history lasted for six years!
indeed, Vicente Soler a volcanologist from the Spanish National Research Council announced this evening that a new vent has opened on the volcano.
Volcanologists were able to give advance warning to the residents near the latest eruption on La Palma, having observed the telltale signs that the arrival of the magma was imminent. Before the eruption, over 25,000 tremors were registered as the volcano prepared to erupt. So far, 5,500 people have been evacuated as the lava rolls down slopes into homes and the sea.
And La Palma is not the only active volcano on the islands.
What is the geological history of the islands?
The lands of Macaronesia, that is the archipelagos of the Canary Islands, Madeira, Azores and Cape Verde, were formed by volcanoes 70 million years ago.
In the last 1,000 years, the only eruptions in Spain have happened in the Canary Islands. This is due to their relative youth amongst volcanos, with Cumbre vieja being a mere 125,000 years old. They are still in the stage of volcano development, which means eruptions can still happen.
La Palma and Tenerife have the most active volcanoes in Spain. Since records were kept about eruptions, there have been 19 eruptions:
