A dormant Spanish volcano threatens to awakenforcing experts to issue an urgent warning to the entire population. Spain is a volcanic area, whether we like it or not, we are exposed to a series of events that can change everything. We are facing some events that are difficult to predict, but they end up being a possibility that is becoming more and more visible. Especially if we take into account the volcanic activity that we have experienced in recent times.
For a few years now, Spain has seen some of its main volcanoes threatening to become active again. Science has advanced a lot, but it is not easy to make volcanoes easy to predict. In fact, nothing is known about them, only the present and the past can be measured, the future seems totally uncertain. What is being seen in recent days is a significant change that may end up being what marks a before and after. For now, experts have decided to launch an important alert in the face of an inactive volcano that is showing signs of change; these are the areas of Spain that are in danger.
A dormant Spanish volcano threatens to awaken
The harsh threat from this volcano who seems to be waking up at times. Spain, and especially the Canary Islands, are a volcanic area that perhaps until now we had not taken into account. The fact that these islands are mostly the fruit of these volcanoes that have made this area inevitable in the past can change everything.
Without a doubt, we are facing a natural element that, as we have seen in the past, can cause more than one impact. We have the most recent case with the La Palma volcano, which left the area devastated. It woke up from its inactivity and devastated the houses and farm areas around it.
This Spanish volcano that is awakening can cause a similar or greater impact on this element. Science is awaiting what may happen in this area of the country, which is the one that registers the greatest activity. Whether we like it or not, we are facing a situation that could end up being much worse than expected.
Experts have had to launch an alert that responds to a series of movements that they have seen arriving for a few days and whose impact may be much greater than expected.
This is the urgent warning from the experts
As the National Geological Institute warns, there is an area of Spain that is at risk from the activity of a volcano that could end up being much worse than expected. The lack of means or situations to predict the effects of this volcano may be what makes an important difference.
These experts explain to us: «On the ocean floor between Tenerife and Gran Canaria there are large extensions of mobilized “debris” deposits that cover part of the ocean floor. Of the various prehistoric landslides described on the southern coast of the island of Tenerife, the Güimar landslide (2,600 km2) stands out, occurring about 800,000 years ago. The depression that remained on the slope has a width of between 9 and 12 km and large lateral scarps (up to 300 m in elevation) and head, and within it are the slid deposits that did not reach the sea interspersed between new historical eruptions. and subhistorical. Its head coincides with the Dorsal Cordillera, the main rift zone of the island, with a NE direction, and maximum heights of 1700-2200 m.
The “debris avalanche” fan on the ocean floor on the coast of Tenerife comes from this landslide and has a volume of materials >120 km3. For its part, the west coast of the island of Gran Canaria has also suffered several gravitational landslides on the high cliffs of the Miocene basaltic edifice on both sides of the Aldea de San Nicolás ravine. In the southern sector (Güi-Güi, and Tasarte and Tasartico ravines) large volumes of mainly basaltic rocks collapsed to the bottom of the sea forming “debris” fans that do not seem to overlap with that of Güimar. For their part, in the northern sector, the largest cliffs on the island, such as Anden Verde and Risco de Faneque, have also suffered major landslides, leaving a large range of “debris” that does overlap with that of Güimar. The Enmedio fault is an area with permanent seismicity and volcanic activity (although not currently) that is not episodic. According to all the earthquakes that have occurred in the fault sector, they are of tectonic origin. The length of the main fault is estimated at about 35 km and it is located very close to the Enmedio volcano. The recorded earthquakes usually have their hypocenter between 25 and 35 km deep, for the most part, although some have been recorded at average depths of up to 70 km. The volcano de Enmedio is an underwater volcano which is located 25.47 km from the Abona lighthouse (Tenerife coast) and 36.2 km from the Village of San Nicolás (Gran Canaria)».
