The La Palma volcano eruption it is being a nightmare for the people living in the evacuated areas. However, fear spreads throughout the rest of the island, and even the rest of the Canary archipelago. Doubts arise among the population as to whether volcanic activity could cause major earthquakes or lead to the eruption of other Canarian volcanoes, such as the Teide.
It is a tense situation and fear, for which social networks do not help much, is logical. However, at least in that sense a call for tranquility. Well no, the La Palma volcano will not be the beginning of a domino of island eruptions.
A single bag of magma
As we already know, that of the La Palma volcano was an eruption more than announced by a large number of earthquakes in the days before.
It is not known how long it will take for the bag to empty, it could be weeks or months
Therefore, it is doubtful whether this could be extended to the rest of the “Isla Bonita” land or any of its neighbors. Even if it could cause an eruption on Mount Teide. Fortunately, things do not work that way, as the geologist, popularizer and scientific illustrator Rubén Aguayo explained to CVBJ.biz. “In this eruption, we have a magma pocket that is pushing up and that wants to come out,” he begins. “Take advantage of fractures, fissures and any gaps to sneak in and if you don’t believe them until you get out. That is what seems to be happening on La Palma, where we have a fissure rash”.
But what does this mean? Basically, “that the magma is going to go out through different places forming cones through which the magma comes out only once (monogenetic volcanoes)”. And this is important, because it allows estimating where these will be produced. cracks. “A fissure may appear in one place, and another 200 meters. But naturally, this is going to happen where the ascension of the magma is estimated to be, which is what seismicity reveals to us, among other things. Neither this seismicity nor any other precursor has been detected in no other part of the archipelago, so this bag of magma seems to be alone ”.
As for how long this event will last, it is impossible to know for sure. “The stock market will empty in the coming weeks or months (according to experts estimate) and nothing more, another eruption in an archipelago, that we do not forget, has volcanic origin”. It should be remembered that the last eruption that took place on La Palma was that of Teneguía volcano, that in 1971 it was expelling lava for 23 days. At the moment it is not known how long it will last in this case. It could be a similar period, but it could also be shorter or longer.
From the volcano of La Palma to Teide
We have seen that the La Palma volcano does not seem to be connected with others on the island. But can there be danger from earthquakes?
“Volcanoes are not usually connected to each other, so there are no chain reactions“
Rubén Aguayo, geologist
Faced with this question, the geologist interviewed by this medium recalls that “earthquakes, although they can be perceived in places far away from the epicenter with the appropriate instruments, they fade right away as soon as they move away from the source ”. “It seems not, but Mount Teide is about 130 km away, so the earthquakes on La Palma will hardly arrive with enough energy to trigger anything on the nearby islands ”. Recall that the largest have had around 4. In addition, Aguayo points out a hoax that has arisen in social networks in which the earthquakes Granada with the volcano of La Palma and remember that this is something totally implausible.
So, going back to that possible fall of dominoes, can there be a chain reaction? The truth is that, according to the geologist, volcanoes are not usually connected to each other so that they can affect each other. “Previous eruptions in the archipelago like that of Teneguía or that of El Hierro they have not caused any kind of indication that could lead to a possible activation of the Teide ”, he recalls. “The general public tends to think that these types of geological events are often interconnected, and that an earthquake in Kuala Lumpur can cause the Chimborazo volcano in Ecuador to erupt. And this is not the case, they are different contexts with different processes and different results that have no relationship between them ”.
Perhaps it is due to a confusion related to how the launch of gases and ashes the atmosphere can affect the climate or even the health of inhabitants of remote territories. That is another story and it will depend a lot on the intensity of each volcano. But, if we focus only on earthquakes and eruptions, it does not seem that there are more dominoes ready to fall. The palm trees have enough with the token that fell yesterday on many of their homes.
